50V range: 106~1011 Ω
100V range 106~1011 Ω
250V range: 106~1011 Ω
500V range: 107~1012 Ω
1000V range: 107~1012 Ω (accuracy within the range of 1012~1013 Ω is not assessed)
5. Test accuracy:
Header indication 1.00~2.0 accuracy ± 5% ± 1 grid
Header indication 2.0~5.0 accuracy ± 10% ± 1 grid
Header indication 5.0~10.0 accuracy ± 15%
6. Charging time:
Instrument: Charging time<0.1S
Capacitor: Capacity<1uF, charging time<0.1S
Capacity>1uF, charging time<0.5S
7. Preset range: (0.1~9.9) x voltage selection multiplier x multiplier selection (M Ω).
8. Sorting function: This instrument has a sorting function. The required value is selected by the preset dial switch. When the test value is less than the preset value, the "defective" indicator light will turn on, indicating that it is unqualified. When the test value is greater than the preset value, the "defective" indicator light will turn off, indicating that it is qualified.
9. Header indication selection:
When the setting/measuring button is pressed, the value indicated on the header is the preset value of the dial.
When the setting/measuring button is released, the value indicated on the header is the measured value.
10. Test fixture measurement/discharge selection:
When measuring/discharging is selected as measurement, measure the components on the test fixture. When selected for measurement - the alarm is also in the measurement state, and the alarm function is turned on. If it is not qualified, an alarm can be sounded.
When the measurement/discharge selection is discharge, discharge the components on the test fixture.
