Notes:
1 Use HIOKI HiTESTER MODEL 3030 or equivalent tester for this measurement, and do not use megger or
other instrument.
2 When the tester's pointer moves, the result is "ON", or "OFF" when not. The value enclosed by ( ) is
approximately value measured using 1kΩ range of the tester. Note that the value varies among conditions of
the tester (internal power supply), measurement ranges and models.
3 Disconnect all connections, and measure as an independent unit.
4 This check provides only rough indication, and perfect measurement cannot be made with the tester.
