We use variety of electrical equipments in daily routine. These electronic gadgets are used because they have made most of the chores much easier and also save a lot of time. These electronic equipments are required equally in household and industrial both the sectors. On the other hand, one can't deny from the fact that these devices and equipments can go wrong anytime. So, it is better to check them regularly to ensure safety of the operator. With the help of varieties of electrical testing equipments, the operator can have the surety that the electrical devices are working correctly. Advanced electric testing equipments provide detail information about the device they tests.
Not all the devices are same so they require different kinds of testing instruments for checking functionality. Some of the common instruments include battery tester, burn-in test equipment, automated test equipment, backplane tester, ammeter, voltmeter, continuity tester, multimeter, oscilloscope, and many others. Let's have a look over these devices in brief:
Battery Tester
The instrument is mostly accompanied by testing equipment for fuel cells. Battery tester is particularly used for testing the performance of the product as it efficiently analyses battery cell's temperature, amperage, voltage, charge, DC resistance etc. Having an idea of these things helps the operator to know about battery's current condition and also to know whether the component still functions or not.
Burn-in Test Equipment
The equipment is used in assistance of power cycling, voltage, and temperature to examine power chips and boards. Burn-in test equipment also assures quality of the device.
Automated Test Equipment
This instrument uses computer to test and measure some specific types of industrial units. Being costly equipment, it also requires professionals for set up and to operate it during different programming stages. The main advantage of automated test equipment is that it doesn't require too much manual interaction and efforts for its efficient operation. The main function of automated test equipment is to test components like interconnections and printed circuit boards.
Backplane Tester
Being an important name in the list of electrical testing instruments, backplane testers are used for testing capacitors and resistors. The prime use of this instrument is in networking.
Ammeter
An Ammeter is used to measure amperage of the electronic device. This amperage ranges from milliamp level up to 10 amps. Generally amperage above 10 amps is measured with a particular type of ammeter that clamps around a wire.
Voltmeter
This instrument is used to measure voltage between two points. In past analog voltmeters were used but today digital voltmeters are in vogue. These digital voltmeters provide more functionality and are inexpensive. In general, a voltmeter can measure voltage ranging from millivolts to hundreds of volts. The instrument can also show polarity of current.
Continuity Tester
It is used to test for conductivity between two points. The existence of continuity results into beep or buzzing noise of the tester.
MultiMeter
A multimeter is a combination of voltmeter and ammeter. Digital multimeters used to measure resistance and continuity both.
Oscilloscope
The instrument is used to measure change in voltage over time and shows the result in the graphical form on the device's screen. These are best chosen for checking the frequency of digital signals and AC voltage.
Apart from above mentioned testing instruments, there are many others that are used to test the electronic devices. Like automatic voltage stabilizer, these instruments are easily available in the physical as well as online market both. There are many suppliers that have made their strong online presence so that customers from any nook and corner of the world can purchase these instruments. So, use these instruments and ensure your safety from electric devices.
