Why is insulation resistance measured by a shake meter instead of a multimeter?
Shaking table with power generation device, according to the needs of different test voltage can be selected, there are 100V, 200V, 500V, 1000V, 2500V, etc., as far as possible to make the measurement closer to the actual state of use, or slightly greater than the actual state of use.
For example: the insulation of the motor becomes worse, but at low pressure can not show, use ordinary multimeter to measure all normal, once the voltage rise, the problem will appear.
Multimeter test voltage of less than 10V, far from simulating the real situation.
