What Is A Digital Multimeter

A tool that is used to measure volts, amps and ohms is called a digital multimeter. These tools are not the same as analog meters, which have needles and gauges. Digital multimeters have digital light-emitting diode displays. These types of multimeters are generally more accurate compared to the old analog types.

Using A Digital Multimeter

This measuring tool has some other functions; of course, the higher priced meters are going to have more features, but they all provide measurements for the three basic currents. There are types of digital multimeters that have specialized functions. Some have built-in temperature sensors that are useful for people that handle temperature-sensitive hardware, like computer processors.

A multimeter is very beneficial when trying to fix an electrical problem. These tools are used quite frequently in businesses such as the automobile industry, machine repair, construction, computer industry, and other fields that call for any type of electrical work. When selecting a digital multimeter, a very important specification to consider is the unit's operating resistance, commonly known as impedance. Since a multimeter becomes a part of the circuit system that is being tested, it will affect the electrical current in the circuit.

An additional specification to take into account when choosing a multimeter will be its range. It does not matter what current is getting tested, the correct range for that particular measurement is essential for the measure to be accurate. For example, if the operator was testing a nine volt battery, then having a range setting from zero to twenty-five volts is going to produce a better measurement than a digital multimeter unit that has a range setting from zero to five hundred volts. Many multimeters are made having an automatic range feature, that will automatically set the appropriate range for the individual circuit that is being tested. Basically, all the operator needs to do is to set the multimeter to the correct current being tested, then the digital multimeter will do the rest.

When working with a meter for the very first time, it is important for the operator to read the instruction guide that came with the unit. Numerous meters will have different steps that have to be taken before it can take any measurements. This could involve certain specific buttons prior to connecting the leads, or anything else. Nearly all of these types of multimeters need a battery for functioning. The instruction guide will probably indicate which kind of battery is going to be needed. When the battery type is not given, then select alkaline batteries.

A digital multimeter's maximum reading capability is really important too. This is the total maximum level of current which the multimeter can measure. Typically, the current limit will be printed on the front of the unit. A standard limit is usually ten amps. Which means that when the multimeter is connected to a current of twelve amps, the interior fuse will automatically pop to avoid damaging the unit. The installation of a larger fuse is not going to raise the limit of the unit and could cause the unit to quit working.

Whether measuring a circuit's capacity, testing a battery, or seeking to identify an electrical short, digital multimeters are versatile devices that should be included in most toolboxes.

Digital and Mini Projectors

Running a business from home has both its advantages and disadvantages. It saves you the commute, especially in bad weather. On the other hand there is no getting anyway from the office. To put together your office you need all the office basics like furniture, electronics and stationary. The electric connections could be a problem. Once you have determined the number of appliances you are going to need, have an electrician come over and check the house electrical system and make the changes it needs.

Set aside a room for team conferences. This room could double up as a lunch room as well. Setup the room with a long table that is not too expensive and not elaborate. After all this is where people are going to have their lunch and accidents happen. Also put up a projector and screen in the room. You could use a whiteboard instead of a screen. The whiteboard will allow for people to illustrate their points and will also double as a screen for the projector.

Choosing a projector will require you conduct a little research. This article will tell you the benefits of digital projectors that will hopefully help you make your decision. Digital projectors are a new relatively new technology that was invented in 1987, but technological and cost constants stopped it from being developed for commercial use. Digital projectors use Digital Light Processing (DLP) technology which is giving LCD, plasma screens and HDTV's a run for their money. DLP is being used to create the ultimate home entertainment system that will allow you watch movies in cinema like surroundings.

Digital projectors are now used on a regular basis to give presentations in businesses and corporations because of their low noise levels, light weight and less power consumption. The digital projectors are also very portable because of their reduced weight as compared to previous projectors. Sales executives are using these projectors for on road presentations because of their portability. DLP's produce shake free images that are clear, bright and distinct. Installing this in your conference room will not only help you with great presentations and with a little more investment you could get a killer home entertainment system that will be the envy of all who see and hear about it.

A new trend in the market is the use of mini projectors. You should consider buying a mini projector for presentations to your potential clients. A small projector that can fit in your pocket is sure to impress and get the meeting off to a good start. The mini projector is small enough to fit in your pocket and is best suited for presentations where the body is primarily text and images, like a PowerPoint presentation. It comes with a battery life of 1.5 hours and an external battery to increase the life by another 1.5 hours is available. It comes with a built in USB port, VGA, HDMI, video and other input / output connections for easy use.

Hard Drives – Digital Space

The first hard drives (HDD) were developed by IBM in 1956. Since then the need for space to store digital information like music, videos, pictures and games has increased many times. While the space of the first drives was measured in tens of megabytes the newest models for home usage can reach up to 3 Terabytes which in converted in megabytes is 3,000,000 megabytes. Of course disk space is not the only characteristic of drives, reading and writing speed is important too, as well as RPM for the noise levels. Of course newer drives are very quiet and will not bother you at all. The standard size of a desktop PC hard drive is 3.5 "and for a laptop (mobile computer) it is 2.5" of course their size may vary from 1 "to 8". The largest 3.5 "drive is 3 Terabytes and the largest 2.5" hard drive is 320 Gigabytes. Of course disk space is not the only characteristic of hard drives, reading and writing speed is important too, as well as RPM for the noise levels. Of course newer drives are very quiet and will not bother you at all. While the space of the first hard drives was measured in tens of megabytes the newest models for home usage can reach up to 3 Terabytes which in converted in megabytes is 3,000,000 megabytes.

Drives consist of platters, heads, actuator axis, actuator arm, spindle and metal casing. The platter is basically a special disk on which data is magnetically recorded. The platters are made of a non-magnetic material which is usually aluminum and are covered with a thick 10-20nm layer of magnetic material. The magnetic material is usually cobalt-based alloy. The platters spin at high rates (5400 to 10000 RPM) and the read and writing heads installed on the actuator arm which is connected with the actuator axis, thus allowing the movement of the heads on the platters which by making contact with the platter write or erase the digital data.

Hard Drives can be connected to drive networks such as RAID, NAS, SAN which combine several hard drives in one. These networks appeared because of the need for greater space by big enterprises and web-sites, but of course you can also use it in your home if you need the space and possess the knowledge to do it.

Drivers are not used only in computers. Every digital video player, music player, camera or phone and others have a hard drive on which you can save your information – they're an important part for almost every piece of mechanical device we use occasionally.

Battery Charger Shootout: BatteryMINDer Plus vs Optima Digital 400



One of my first upgrades on my 2004 Toyota Matrix (Corolla Wagon according to the title) was installation of an Optima REDTOP. I had to customize the battery bracket since the battery was actually smaller than stock. The car did not always see a lot of highway miles which allows the alternator to recharge the battery, so I used the BatteryMINDer Plus every 6 months or so to keep the battery maintained. I recently got an Optima Digital 400 and just 15 minutes with that really woke up the Optima battery. Everything works better with a fully charged and conditioned battery, engine performance, stereo, lights, etc.

Long story short, if you have an Optima battery, get the Optima charger. Whatever tweaks they did to the “charge – condition – maintain” technology provides for a real difference in my experience.

The Stanley satellite rechargeable LED work light (SAT3S) is awesome by the way!

Integration Technologies For Digital Imaging

Medical specialization areas can take advantage of the flexibility that comes from using digital medical imaging, with images stored in the Dicom format. For urgent care, podiatry or chiropractic clinics, taking the medical images you need using urgent care DR, podiatry DR or chiropractic DR imagers is an excellent starting place for integrating other medical technologies in order to make your medical office or hospital more productive while improving patient care.

DICOM Format

Various digital imaging acquisition modalities, such as PET, CT, MRI, mammography, ultrasound, digital x-ray systems such as an urgent care DR device and others, utilize the medical imaging format known as DICOM, which stands for digital imaging and communications in medicine, in order to improve integration among different types of commonly used medical equipment and data.

For example, a PACS system will allow you to view, distribute or archive your DICOM digital medical images regardless of which modality they came from, as long as the images are stored in DICOM format. An RIS system will allow you to save text documents in DICOM format as well, thereby integrating images and text in a format that allows them to be stored as well viewed together, making for a more complete digital patient record for better patient care.

PACS Systems

A PACS appliance is an extremely versatile integration component for hospitals and medical facilities of all sizes. Once you have taken your digital images on your podiatry DR or chiropractic DR system, the imager can save the digital medical image in DICOM format. Your PACS will read DICOM format, and through the PACS you have the ability to integrate your communications through your medical network.

Physicians in your immediate medical facility can all view the same medical images simultaneously through the PACS, as well as send and receive the digital images online. Now expand that same technology to include a wide area network and virtual private network, and you can see that you can integrate your digital digital documents saved in DICOM with any authorized personnel anywhere in the world online, expanding consultation potential.

Digital Image Archive

Storage of your patient records is of vital importance in providing excellent patient care. By saving digital images and text in DICOM format, you can now also integrate into your digital imaging system the ability to archive the digital patient records automatically. Your archive may be located onsite, and you may also send DICOM records to an offsite server as well in order to maintain HIPPA compliance concern disaster recovery.

Through the use of DICOM format, all of the related medical technologies used daily for digital medical images can be integrated, helping to improve cost effectiveness as well as your medical office or hospital workflow.
