To test an IGBT with Multimeter, the meter should be used in diode-checking mode. It should have battery voltage of less than 20V (a typical. The INSULATED GATE BIPOLAR TRANSISTOR (IGBT) is a STEP-1 – IGBT TESTING WITH MULTIMETER: IGBT DATA SHEET. Most manufacturers IGBT devices are % tested before shipping and Equipment Requirement – DMM with diode check mode and battery voltage less than.
