Product Functions:
1) With positive/reverse wiring, internal/external standard capacitor, internal/external high voltage multiple working modes, integrated structure, can perform various conventional dielectric loss tests without any external auxiliary equipment.
(2) With four-channel positive wiring mode, convenient for transformer bushing dielectric loss tests.
(3) With external standard capacitor interface, automatically tracks external test power frequency 40Hz~70Hz, supports power frequency and series resonance power for large-capacity high-voltage dielectric loss tests.
(4) With loop poor contact discharge indication function, to facilitate judging whether wiring is reliable.
(5) With CVT self-excitation method measurement function, C1/C2 can be measured simultaneously with one wiring, automatically compensates for bus grounding and standard capacitor voltage division effects, no need to change wires or connect any external accessories, and high-voltage connecting wires can be dragged on the ground.
(6) With CVT ratio function, can measure CVT ratio, polarity, and phase error.

Operation Precautions:
1. When using, the instrument grounding terminal must be reliably grounded.
2. Only when the instrument power is turned off and the internal high voltage allow switch is set to “Off” position, contacting the rear of the instrument and its measurement cables with the test object is considered safe.
3. During measurement, it is strictly prohibited to operate the “Test Voltage” selection switch.
4. In positive wiring method, the UH terminal is high voltage; in reverse wiring method, the IX terminal is high voltage. When using, must keep sufficient distance between high-voltage cables and ground according to actual conditions, except for special cables when test voltage is below 10KV.
5. Do not replace fuse tubes that do not match the panel indication values.
6. When using, use the cables provided by the manufacturer as much as possible to ensure measurement accuracy.
