● Insulation resistance measurement
- When insulation resistance like a capacitive load is measured, electric
charges stored in a capacitive circuit are automatically discharged after
measurement. Discharge can be checked with the live warning LED, red
backlight, blinking symbol on the LCD and buzzer.
- Bar graph display
- Buzzer beeps when the measured value drops below or exceed the
pre-set threshold value.
- For safety reasons, a long press is required to select 1000V range.
It is possible to disable 1000V range.
* Special features for measurement on PV systems
- Measured voltages are displayed in stand-by mode.
- Elapsed time, after starting a measurement, is displayed with the
measured values.
- Auto-discharge with voltage display and also with the measured value
● Earth resistance measurement
- Measured earth voltage is displayed in stand-by mode. The LED lights up
if the measured voltage is relatively high.
- In precision measurement, warning indication will be displayed and the
LED lights up if the auxiliary earth resistance it too high.
- Easy to perform simplified measurement with two test probes on simplified
measurement function.
- Buzzer beeps when the measured value drops below or exceed the
pre-set threshold value.
