Multimeter is a device with a combination of two devices: a voltmeter and an ammeter and it can be used for metering. This implement is not expensive and is available in two forms analog and digital. Digital multimeter instruments display readings in numbers while Analog multimeter instruments indicate the value with a needle over a scale. It also helps to measure resistance and continuity. It is helpful in measuring and checking the batteries, diodes and transistors as well.
Some expensive multimeters can help in measuring temperature as well. They can be used for simple problem solving or taking dimensions in fields. They can be used for residential or commercial purpose in manufacturing units for measuring electrical output with good accuracy.
The digital multimeter is fast gaining popularity over the conventional analog multimeter due to the low cost of manufacturing involved in it. It consists of multifaceted machinery and is used in many different fields by electricians, electrical engineers and service technicians in industries ranging from car repair to computer repair and more. The professionals require more complex and expensive multimeters to suit their needs. Though multimeter instruments are available in the retail market it is better to buy them online as they are likely to have a wider range of multimeters for display.
Electrical test equipment are devices that allow for testing of electrical appliances to reduce the risk of accidents. This test equipment can be of various types and can be categorized on the basis of the industry that uses it. The most common electrical test equipment includes:
Battery Testers: They scrutinize the battery cell’s hotness, charge, resistance, and voltage resistance.
Backplane Testers: They help in high speed communication and can be used for efficient networking.
Burn-in Testing Equipment: It helps in analyzing power chips and boards with the use of temperatures, power cycling and voltages.
Automated Test Equipment: It is the most advanced of all the electrical test equipment systems. It is used to examine a range of machinery like interconnections, verifications and printed circuit boards.
PAT testers serve the purpose of testing electrical appliances so as to prevent the risk of accidents related to electrical appliances. PAT tester instruments are very functional in homes. There are three types of testers that are available in the market. These include:
The Basic Testers: The most common is the pass or fail PAT test which is the most simple and easy to understand test.
The Advanced Testers: This test projects additional test data.
Computerized PAT Testers: The information is downloaded from the computer in these kinds of testers.
