Customer Service3 天之前· A. Insulation Resistance (IR) is the extent to which the dielectric material in a capacitor resists leakage current. It is the resistance of the dielectric material itself*1. IR is measured by leakage current. Knowing the leakage current and applied voltage, the insulation resistance can be calculated based on the ohm''s law.
Customer ServiceTo check a capacitor in the resistance mode, perform the following steps: Remove the capacitor to be tested from the electric board. Discharge the capacitor completely by connecting it across a resistor, and remove the capacitor thereafter for testing. Twist the selection knob and select a value in the OHM range, say 1kΩ.

Discharge the capacitor completely by connecting it across a resistor, and remove the capacitor thereafter for testing. Twist the selection knob and select a value in the OHM range, say 1kΩ.
The current from the measuring device first flows into the capacitor until it is fully charged. The resistance measurement can then be carried out. The reading on the display then shows a continuously increasing measured value until the measuring range is left and only a 1 is displayed.
So, grab your multimeter and follow the steps below. Disconnect your ceramic capacitor from the device and ensure it is fully discharged. Check its capacitance value that is displayed on the capacitor. Choose the capacitance mode on your digital multimeter. Connect the testing probes with the capacitor’s terminals.
For a complete test of the capacitor, the measuring lines must be applied twice and the reaction of both processes must be compared: On the display of the digital multimeter, a measured value should now be shown for a fraction of a second that you have to remember. The measurement display will then immediately jump to OL (Open Line).
Bear in mind that capacitors that are measured in nano farad and microfarad are simple to check. However, you will need a special type of multimeter to measure small ceramic capacitors (measured in picofarad). In this section, we will show you the straightforward and easiest way to test those capacitors.
In this example we'll consider a ceramic capacitor of 2.2uf (2.2x10-6 farads) with a typical minimum insulation resistance of 2GW. If a capacitor is tested at 200V and measures a dielectric leakage current of 10nA the insulation resistance must be 20GW.
