Page 11: Starting The Test
For test objects with low capacitance, such as cables under 100 meters, a supplied standard capacitor must be connected in parallel during the test. SHIELDING CONN. In tan delta test, select "single" or "double" according to the actual test leads connection . In VLF or DC test, select "NO"...
Page 12 Description Item VOLTAGE The test voltage being applied. CURRENT Current output during test The relevant standards usually recommend a test frequency of FREQUENCY 0.1 Hz for cable tests with VLF voltage. The maximum test frequency depends on the determined cable capacity and the test voltage being applied.In order to ensure the safety of the device, the device automatically adjusts the test frequency according to the capacity of the cable and the test...
