The insulation resistance watch is also called Zhao European table, shake watch, and Meg watch.The insulation resistance table is mainly composed of three parts.The first is the DC high -pressure generator to generate high voltage.The second is to measure the circuit.The third is display.It is used to measure the dedicated instrument of maximum resistance, insulation resistance, absorption ratio, and polarization index. Its standard unit is Zhaou, which itself has a high -voltage power supply.
Insulation resistance meter use
Introduction to the purpose of the insulation resistance table 1. Insulating resistance tables are often used in some insulation resistance measurement measurement of electrical equipment, such as transformers, transformers, electric motors, power cables, lightning pins, etc.The more accurate measurement of the resistance of those electronic facilities enables those electronic facilities to run normally.

At present, most of the test insulation resistance tables still use shake watches, with 500V, 1000V, and 2500V commonly used.Select according to the voltage level of the tested equipment.Low -pressure equipment is 500V.
How to use the insulation resistance table
(1) Before the measurement, the power supply of the measured equipment must be cut off, and the ground is discharged short -circuit. The equipment is not allowed to measure the power to ensure the safety of personal and equipment.(2) For equipment that may be sensitive, it is necessary to eliminate this possibility before measurement can be performed.(3) The surface of the measured object should be cleaned to reduce contact resistance to ensure the correctness of the measurement results.(4) Check whether the instrument is in normal working state before measuring, and mainly check its "0" and "∞" points.The Zhao table is shaking the handle to make the motor reach the rated speed. When the Zhao table should be in the "0" position when it is short -circuit, it should be at the "∞" position when opening the road.(5) The instrument should be placed in a stable and solid place, and stay away from large external current conductors and external magnetic fields.After doing the above preparation work, you can measure it. During the measurement, you should also pay attention to the correct wiring, otherwise it will cause unnecessary errors or even errors
