Features
(1) Tests can be performed by selecting resistors of 10 mΩ to 100 mΩ.
(2) By using a short circuit electrode, it is possible to conduct a short circuit test without using a resistor.
(3) When selecting the resistance value, the electromagnetic contactor is thrown in time sharing to suppress inrush current.
(4) Standards UL 1642, JIS C 8712: 2006, 4.3.2, etc. can be tested.
