Care must be taken to not apply voltages beyond the insulation rating to over-current devices or the spring charging motor while testing controls wiring. Additionally, one must ensure that the circuit or device being tested is isolated.
Micro-Ohmmeter or Contact Resistance Test
There may be many surfaces that carry current, and they should be properly maintained. Contact resistance testing is a good way to evaluate the condition of electrical contact points. Micro-ohmmeters are ideal for conducting contact resistance tests because of the requirement to accurately measure and display very low values of resistance.
