Power Supply

(1) Use AC220 (1±10%) V, 50 (1±2%) Hz power supply. External power supply voltage deviation may cause measurement errors, abnormal operation of the instrument, or damage to the instrument.

Wiring

(1) For the safety of the instrument and operators, the instrument must be reliably grounded.

(2) During test preparation, connect the ground wire first, and remove the ground wire last after work is completed.

(3) Ensure that the test object is isolated from high-voltage lines, and all personnel must stay away from high voltage.

(4) Before testing, disconnect the parallel branch at the test end.

(5) Before wiring, ensure that the power switch is in the OFF position and the high-voltage enable switch is in the OFF position.

(6) Before starting the test, connect the high-voltage cable to the tester first, then connect the other end to the test object. After the test, disconnect the high-voltage cable from the test object first, then remove it from the tester. This is to prevent injury to personnel and damage to the instrument from induced voltage on the test object.

(7) Do not plug or unplug any wiring while the power is on.

(8) For safe and proper use of the instrument, do not arbitrarily replace test leads.

(9) If any suspicious problem occurs, stop operation immediately and have it checked by our company's technical personnel.
