We know that in order to ensure whether the fine state of the electrical operations in process, one must incorporate low resistance testing. This is also how we determine that the equipment is functioning with minimum resistance involved, a state that is of great importance for the identification of the test equipment that will be mostly compatible with a given working environment. Here are the most common resistance testers that rock the world of engineering, along with some of their key characteristics:
Millioohmmeter
In comparison to the micro ohmeter, this piece of equipment measures the resistance with a greater sensitivity and the calibration it features makes it suitable for measuring the resistance of the general electrical circuits. The test current ranges from 0.2 to 2 amperes. The tests are conducted with one purpose in mind – ensuring that all of the circuit components are in perfect balance and there is regularity present in the flow of the current.
10 Ampere Micro-Ohmmeter
Massive instruments and this type of low resistance ohmmeter go together like a knife and a spoon. These devices can cover all there is to cover industrial applications wise. Let’s not even get started on how the battery life can be extended while the loads can be reduced. You can select manual, continuous or automatic mode, depending on the industrial environment, however, the awesomeness that comes with the accuracy of these devices is here to stay. The highest level of resistance that can be measured with this Micro Ohm Meter is 2000 Ohms. These incredibly useful devices can be mostly taken advantage of in environments where work usually and predominately centers around circuit breakers, welding joints, lightning conductors and wires.
200A Low Resistance Microohmmeter
This device is in fact a portable high-current instrument, controlled through a micro-processor. It features protection for measurement in all electrical substations and optimized filters. We urge you to use this model if your goal is to most accurately measure extremely low contact resistances, especially when it comes to busbars, switches and circuit breakers. The test current can reach as high as 200A. This microohmmeter makes use of the 4 terminal – method Kelvin principle fro the purpose of eliminating errors most likely caused by test leads.
Knowing what you are working with and having the freedom to test, experiment and share knowledge like this is what makes engineering a fun field to delve into. The thrill of finding endlessly inventive solutions to the constantly arising problems is the reason why such devices are here for us to benefit from and use.
