An Affordable Digital Multimeter For The Electronics Enthusiast

blogger

The multimeter is one of the most useful pieces of electrical test equipments. As it can measure amps, ohms and volts. Its true, it really combines three functions. When you need to measure current, it becomes an ammeter. When you need to measure ohms, it becomes an ohmmeter, while you need to measure voltage, it becomes a voltmeter.

You can imagine that digital multimeter can be used in industrial applications, electrical applications, diagnose your vehicles or home usage. Multimeters come in two parts: digital and analog. The analog one has a needle, while the digital one has a LED or LCD display. We know digital products always in advance, and has trend that is to replace the analog ones. The digital one not only can be readout directly, but also can be adjusted automatically.

The types of digital multimeter come in two kinds, one is handheld, another one is desktop. In fact, multimeter are used very frequently, handheld digital multimeter will be more practical than desktop one. In other hand, handheld multimeter is much cheaper than desktop multimeter.

There is a price range of digital multimeter from several dollars to several thousand dollars. The price you pay all depends on what features you need, and how much you are willing to spend. However, if you are a beginner engineer or enthusiast, it is suggested that you neednt buy an expensive one, or it will lead a waste. You dont be worried, as any digital one has a function with measuring current, ohmmeter and voltmeter. You can buy a good brand with affordable price, such as Hantek digital multimeter.

If you are looking for a digital multimeter to begin your career or for your hobby, dont be hesitated, youroscilloscope.com will offer you more choices. You might want to know more specific details about digital multimeters in my other reviews.

Electronics Gadgets, 13+ Disclaimers And Disclaimer Templates To Keep You Out Of Trouble

blogger

Selling electronic gadgets can be a tricky business, because the products tend to be both physically fragile and can be prone to malfunction. One way to protect yourself is by using disclaimers.

Article Ref: S01GDR

Customers could begin returning defective gadgets in large numbers – disclaimers can protect you from being liable for a replacement or refund.

You must also look at packaging and your transit company’s shipping warranties, as deficient products and services in this regard can lead to damaged goods reaching the customer.

Some issues that may require disclaimers include:
* Laws in different countries
* Electronic standards used in different countries,
* Different operational methods
* The difficulty of installation
* Potential health hazards

** A Typical Disclaimer **

Usually labelled as Terms & Conditions, Important Terms, Disclaimers, Warranty and Exchange Information, or something similar. It’s usual to use several disclaimers to cover as many of your requirements as possible:

* Condition of the item being sold. Condition of the packaging.
* Shipment restrictions – which countries will you ship to? Is there a shipping warranty?
* Recommendations for restrictions on the products use – not to be used around pets or by small children, for example.
* Accepted payment methods.
* Availability of refunds, exchanges and warranties.
* Legal restrictions on the products use.

** Disclaimer Examples **

The following are somewhat random examples of disclaimers, all taken from eBay. Obviously, you’ll have to tailor each disclaimer to each product and your own shipping/payment/warranty/restriction needs.

** GSM Cell phones:

Online electronics gadgets sellers often need to add disclaimer notices to their cell phones because not all GSM cell phone network uses the same frequency.

With the traditional 2G and 2.5G networks there were four main frequencies: 850MHz, 900MHz, 1800MHz and 1900MHz.

Phones that used 900MHz, and 1800MHz bands traditionally worked in most countries (with the exception of the US, North America and US territories) while 850MHz and 1900MHz phones traditionally worked in the US, North America and US territories.

The 3G system has further compounded matters by working on a different frequency and not being compatible with some phones being produced now.

A good disclaimer for GSM cell phones would read as follows:

————————————————————————————————————
NOTE: This product is compatible with GSM at the frequencies of 900MHz, 1800MHz. This cellphone will not work in North America.
————————————————————————————————————

** Radar Scanners:

While radar scanners are popular, it is illegal to buy, or use them.

This is largely because their main purpose is to identify speed cameras or police officers to avoid speeding tickets. This essentially explains both its illegality and its popularity.

To cover yourself include the following disclaimer:

————————————————————————————————————
NOTE: Certain countries prevent the use and ownership of these devices. You are solely responsible for finding out whether this product is legal to import and/or use in your country. We will send you the products you order and cannot accept any liability for customs issues or any implications of your ownership or usage of this device.
————————————————————————————————————

** Ni-Cad Batteries:

Ni-Cad batteries have a memory, as a result they work better and have a longer lifespan if they are charged a certain way when they are first used.

As a result this would be a good disclaimer:

————————————————————————————————————
NOTE: Ni-Cad batteries give their best performance if fully un-charged and charged three times after purchase.
————————————————————————————————————

** Cell Phone/Wi-Fi/radio signal blockers:

Like radar detectors these items are not exactly legal in all situations. However, this doesn’t stop them being popular to certain people.

This is a suitable disclaimer to use with blockers:

————————————————————————————————————
These devices may not be permissible to import into certain countries due to licensing of broadcast signals or other restrictions. Please check your country’s telecommunications regulations before placing your order.
————————————————————————————————————

** Thermometers:

You’re not a health professional. The chances are the people buying these electronic gadgets from you won’t be either.

This won’t stop them blaming you if a loved one became seriously ill if they were ‘misdiagnosed’ because of a reading from a thermometer they brought from you.

To cover yourself include the following disclaimer:

————————————————————————————————————
Note: This device is meant for personal uses only, please refer to a physician or health professional.
————————————————————————————————————

** Breathalyzers:

We all know why people buy breathalyzers. It’s for them to check whether or not they are able to drive home, or whether they will need to catch a cab.

As a result, if they fly too close to the wind and get caught they’re going to try to use YOUR device in their defense.

This is a suitable disclaimer to use in this case:

————————————————————————————————————
Note: This is a reference tool only and can not be used as a legal defense.
————————————————————————————————————

** GPS Devices:

The type of disclaimers you need on GPS devices depend on the type of devices you are carrying and the level of support you are willing to give to customers.

If you are dealing with GPS receivers for example and are sourcing from a factory which offers GPS ready devices that don’t come with the necessary maps then you will need to let customers know that they will need to supply their own maps.

It is worth noting that very few vendors from China actually supply the genuine GPS map software and it may be worth getting a test order of a GPS receiver sent to yourself to make sure you’re not selling GPS devices with software that is cracked or a sample.

To cover yourself include the following disclaimer:

————————————————————————————————————
The unit includes evaluation GPS software only. We recommend purchasing a GPS software package from your home country that best covers your region of the world.
————————————————————————————————————

** GPS Trackers

A number of problems can arise from the sale of GPS trackers. If the tracker is small they can be used for nefarious purposes (maliciously keeping track of family members and loved ones for example). A customer may also expect to see GPS software when none is included.

As a result, you may want to include one of the two disclaimers:

————————————————————————————————————
This model does not come with any GPS navigation map software
————————————————————————————————————

————————————————————————————————————
Seller takes no responsibility for harm resulting from misuse of this item
————————————————————————————————————

**Heart Rate Monitors:

You’re not a health professional. The chances are the people buying these electronic gadgets from you won’t be either.

This won’t stop them blaming you if a loved one became seriously ill if they were ‘misdiagnosed’ because of a reading from a thermometer they brought from you.

To cover yourself include the following disclaimer:

————————————————————————————————————
Note: This device is meant for personal uses only, please refer to a physician or health professional.
————————————————————————————————————

** Car DVD Players:

If you have ever dealt with car stereos (or anything else to do with cars or electronics) you’ll know how complicated they can be.

You’ll also know that the average consumer loves to blame you for their goof-ups.

As a result it may be a good idea to include this disclaimer with any car DVD players you sell

————————————————————————————————————
For optimum performance we recommend that you have this car DVD unit installed by a professional.
————————————————————————————————————

** Spy Listening Devices:

While spy listening devices may seem cool it is illegal to use them in some locations and courts of law will not allow recordings from them to be used as evidence unless both parties taped have signed release forms.

To cover yourself include the following disclaimer:

————————————————————————————————————
NOTE: Certain countries prevent the use and ownership of these devices. You are solely responsible for finding out whether this product is legal to import and/or use in your country. We will send you the products you order and cannot accept any liability for customs issues or any implications of your ownership or usage of this device.
————————————————————————————————————

** Fish Finders:

Fish are notoriously difficult to find. Even with a fish finder. As a result you will need to protect yourself in case somebody they complain that they haven’t been able to spot any fish.

To cover yourself include the following disclaimer:

————————————————————————————————————
Seller takes no responsibility for environmental factors which may inhibit the performance of this device.
————————————————————————————————————

** Chargers:

Regardless of whether you are selling a back-up battery or a solar charger there are always issues surrounding the connection type the voltage and the specific capacity of devices it is compatible with.

As a result you will need to list all the relevant details that apply to the charger you are listing and include the following disclaimer:

————————————————————————————————————
This charger is only compatible with devices with the specifications listed. Please pay careful attention to the listing.
————————————————————————————————————

** Spy Cameras with Audio:

While surveillance cameras are perfectly legal and respected cameras with audio devices are not.

To be used in a court of law both parties taped have signed release forms.

To cover yourself include the following disclaimer:

————————————————————————————————————
NOTE: Certain countries prevent the use of recorded audio footage to be used as evidence in legal cases. You are solely responsible for learning and adhering to the standards of your country when using this product.
————————————————————————————————————

** Car Electronics:

Depending on the age of electronics used in the car a number of issues may arise.

Most of these issues surround the compatibility between the device you are listing and the car that the potential buyer wants to put them in to.

You may want to include the following disclaimer:

————————————————————————————————————
This device is only compatible with devices with the specifications listed. Please pay careful attention to the listing.
————————————————————————————————————

As I mentioned, these disclaimers are examples of what they should look like – you may want to write a disclaimer that suits your particular needs as a seller, taking into account the qualities of the product in question and both your location and the location of your customer.

Digital Book World Conference and Consumer Electronics Show Past and Present

blogger

A number of conferences dealing with electronic technology occur on a regular basis. Two of these are the Digital Book World Conference and the Consumer Electronics Show.

The Digital Book World Conference, a conference on publishing and digital change, is for all book-publishing professionals. This includes senior management, editors, agents, marketers, digital strategists, and others. It is unique in that it helps publishers address business challenges created by digital change.

The first annual Digital Book World Conference took place in New York City January 26-27, 2010 at the Sheraton Hotel and Towers. Planners of the conference conceived the idea in June, put together the Conference Council in July, and drafted the initial program in August. They geared panels and talks towards the changing digital book business. It had three main themes: Evolving the Business Model, EBooks: Opportunity or Threat, and Marketing in the Digital Age. Topics discussed included management of digital rights, pricing of eBooks, and timing of eBook releases. The goal was to provide an outstanding program with expert speakers for attendees to takeaway practical ideas, and to include sponsors and exhibitors capable of offering appropriate tools for implementing the strategies individuals learned about at the conference.

Attendees were professionals from five continents representing more than 240 publishing companies including Amazon.com Digital, Barnes&Noble.com, Crown Publishing Group, Google, HarperCollins, Macmillan, National Geographic Society, Oxford University Press, Princeton University Press, Random House, as well as many others. Individuals from all areas of book acquisition, production, and distribution were present at the conference. Among them were CEOS, Senior Agents, Directors of Marketing & Sales, Editorial Directors, Directors of Strategic Partnerships, and Directors of Digital Assets.

The second annual conference, Digital Book World 2011, coming up January 24-26, will again be held at the Sheraton Hotel and Towers in New York City. The theme this year is Managing Risks; Seizing Opportunities. On Monday, January 24, conference attendees can participate in three-hour workshops in the areas of eBook Design and Production, Content Strategy and Transmedia Development, and Direct-to-Consumer Marketing and Sales.

Planning for this years conference is well ahead of last years schedule. As they plan for the upcoming conference organizers need to predict what the relevant digital change questions will be and what will be relevant to the target audience of book-publishing professionals in January 2011.

The Conference Council, a group of about 30 made up of CEOs, representatives from large and small publishing houses, retailers, digital strategists, retailers, and independent leaders, will plan the programs and choose speakers who will address the relevant issues and problems that trade publishers are facing as they move into digital publishing. Not only is the technology of e-readers progressing rapidly, but e-Ink technology is improving alongside it opening new horizons for digital reading. According to the review “What’s Next in e-Ink Technology”, the new generation color E Ink products are certainly crisper and offer better resolution and color reproduction that anything else seen to date and we expect to see electronic ink begin to compete with LCD displays (Digital Book Readers).

Another conference, the International Consumer Electronics Show (CES) is held each year in Las Vegas, Nevada. The Consumer Electronics Association (CEA) puts on this technology-related trade show, which is not open to the public. Attendees must have a professional affiliation with consumer electronics. The CEA reinvests all profits from the show. They go towards such things as industry promotion and services, technical training and education, development of engineering standards, and legislative advocacy.

Originally, in 1967, CES was held in New York. Then in 1978, it started being held twice a year. In 1998 the show once again changed and went back to the once a year format. The CES gained popularity in 2004 after Comdex was cancelled.

The 2010 Consumer Electronics Show, held January 7-10, had an attendance of more than 120,000. The most impressive e-book readers at the show were Skiff Reader and Plastic Logic Que proReader touchscreen devices with integrated 3G. Also at that show, several companies announced 3D-compatible HDTVs and four companies announced standalone 3D Blu-ray players. Intel demonstrated a new Wireless Display technology (WiDi), and Motorola introduced the new Backflip Smartphone.

The next CES, January 6-9, 2011, will have more than 300 conference sessions covering every aspect of the consumer electronics industry. The full conference lineup will be available October 1, 2010.

Tips for Storing Computers and Electronics in Self Storage

blogger

While household items like furniture are very straightforward to put into self storage, what do you do about electronics and computers? These delicate items must be carefully packed and stored to prevent damage. While water is obviously hazardous, extreme heat and cold can also damage electronics.

Here are some tips to keep your electronics safe in storage.

Why Should You Avoid Storing Electronics?

Before we discuss the best ways to store electronics, it’s important to understand why you should avoid putting electronics into self storage at all, if possible. When the weather gets hot, the temperature inside storage units skyrockets, just like a car, unless the unit is climate controlled. This can easily destroy sensitive electronics, including computers and flat-screen televisions.

Choosing the Right Storage Unit

Most self storage facilities have several types of units to choose among. With electronics, you will always want an indoor climate controlled storage unit. The temperature in these units remains between 50 and 80 degrees with central heat and air, which prevents corrosion or cracks that damage electrical components.

Moisture control is just as important as temperature control when you choose a self storage company. Choose a company that uses a dehumidifier to keep out dampness if you live in a humid climate.

Tips for Safe Electronics Storage

Always begin by backing up all important information and storing it elsewhere. Take the tapes out of any VCRs or devices, and the CDs and DVDs out of drives and players. Equipment should be covered with cotton sheets or canvas — never plastic — to allow air to circulate. Plastic should never be used, as it traps in moisture. If you can, store your devices in their original boxes.

While your storage unit is empty, add pallets or boards to raise your electronics off the floor. Use cardboard or bubble wrap to protect screens, scanners or monitors and mark all glass parts as fragile to avoid placing any heavy or sharp objects against them.

If you have any questions about how to safely store your electronics, check with the self storage facility manager. You may also want to ask about storage insurance, particularly if you are going to store valuables. Above all else, remember that you should never store anything that you can’t replace. Think carefully about storing electronics, as they are at a greater risk of being damaged in storage from the elements and no one wants to pay to store something that is no longer functioning.
