Some Of The Most Popular Test Meters Used By Electricians

Posted by millerross007 on September 2nd, 2019

Electricians all across the world make use of test instruments in their day-to-day professional tasks. These test and measurement instruments are expected to meet all necessary requirements of the relevant regulations. Testing activities need to be carried out using an approved test instrument, if you want the best and most accurate results. There are a number of online services available online, that can help you achieve accuracy with less than 2% deviation from the real value. Thanks to several technological reformations, the modern day tools that are taken into account are highly efficient as well as robust, but to keep using them for a longer period of time would require you to treat them carefully. You might be surprised with this, but the cost of a certified test equipment can cost as much as a high-end camera. If you are paying thousands of dollars for a device, it certainly deserves care and consideration.

That being said, here is a list of the most commonly used test meters popular among electricians.

Earth Fault Loop Impedance Tester

This device is capable of delivering fault currents that is as high as 25A for up to 40ms using the supplied voltage. It basically makes use of Ohm’s law and calculates changes during the test process and shows test results.

RCD Tester

When circuits are shielded by using an RCD (Residual Current Device), a test is done to make sure that that the device functions optimally under fault conditions and it does not exceed the time limit provided by IEE (Institution of Electrical Engineers).

Insulation Resistance Tester

This is a unique test equipment that is able to detect insulation leakage occurring between live conductors and earth.it can do this between live conductors. In the right working condition, this instrument has the capability to produce a test voltage of 250, 500 or 1000 V and deliver an output current of 1 mA or above.

Continuity Tester

It can accurately measure resistance of conductors. A continuity tester is capable of producing an open circuit voltage in the range of 4V and 24V AC/DC, and deliver a short-circuit current above or equal to 200 mA. Continuity testing and insulation resistance testing complement each other to give users the best results.

If you in the market looking for high quality electrical test equipment services for your organization, check with a specialist manufacturers who can fulfill your criteria. A facility that is traceable to the NIST (National Institute of Standards and Technology) series of International Quality Standard is something that you should consider.
