FEATURES
・Low resistance measurement is required for EV motorsand generator if the DTC code “P0A78 (Drive Motor "A"
Inverter Performance) is detected.In this testing, the
resistance to be measured is very low around 100mΩ.
・2-terminal measurement like normal Digital Multimeters
is not suitable for this level of resistance due to the
errors of impedance contribution of the wiring and
contact resistances. It can eliminate such errors by 4-
terminal measurement which assures the accurate testing
