Notes and Instructions:1. This instrument is equipped with a range (test range) adjustment function. In use, it can reduce the test voltage as much as possible to reduce energy consumption, extend instrument life, and reduce safety hazards. It can also reduce test time and improve efficiency. It can be used for group screening and inspection discrimination. Users can fully and reasonably utilize this function.
Preset Voltage Adjustment Range: 0V ~ 1800V
Range Voltage Adjustment Range: 100V ~ 1999V
If the range setting or test value exceeds 1999V, the display shows an overflow signal "1".
2. The preset voltage value for discharge tube testing is the starting value of the 100V/S rate rising voltage and also the lower limit of the test range. The preset voltage for varistor testing is only used as the lower limit for judgment; the actual lower limit of the test range always starts from 0V.
3. The preset voltage should be set lower than the range upper limit voltage. Otherwise, the test voltage will be under the range (upper limit) control state. During varistor testing, a buzzer sound will indicate over-range after each test; during discharge tube testing, the green light will be repeatedly lit, accompanied by an over-range sound prompt. At this point, reducing the preset voltage will bring the high voltage back to the preset state.
4. The test voltage of this instrument can be as high as 2kV. Keep the panel, test leads, and work surface clean and dry to avoid test errors caused by leakage current, arcing, or corona.
5. A two-phase three-wire power socket must be used, and the ground wire should be properly grounded.
6. Operators should take necessary high-voltage protection measures to avoid electric shock.
