If you require accurate measurement of the resistance of the resistor, through the bridge (digital) for testing. Insert the resistor bridge air circuit breaker measurement side, select the appropriate range, you can read from the display resistor values. For example, a resistor or a resistance wire made of a fixed resistor for processing to obtain a more precise resistance value, the measurement electric meter using the bridge resistor.
Use of different occasions, the application of varistor objects, effects on the varistor voltage / current stress is not the same, and thus the varistor requirements are not the same attention to distinguish this difference, it is very Circuit breaker the proper use of the. Depending on the purpose of the different varistor can be divided into two categories: protection varistors varistors for circuit function.
