meter will slowly return to zero, but the high-voltage power supply may have no
electricity.)
3. DC high voltage measurement
After correct connection, press "power switch” of LV display meter, switch
the function switch to DC gear, select “high” gear, DC high voltage can be
measured, LCD display value is the measured DC high voltage value. If
measuring voltage is lower than 20kV, you can switch function switch to “low”
gear in order to obtain higher accuracy. After test, cut off high voltage, LV
display meter returns to zero, then you can enter the site. Note: When
measuring DC, because there are filter capacitor, you must firstly discharge
after completed measurement, then you can near the HV divider.
4. Use High-voltage divider singly
High-voltage divider can be used alone with the common multimeter
instead of LV display meter. The divider ratio of High-voltage divider is 1000:1;
the display value of multimeter multiplied by 1000 is equivalent to the measured
high voltage value. Changing the unit of the display value in multimeter to kV is
ok.
VIII. Change battery
Open the LV display meter, if you find vague LCD display or no response,
indicating that the instrument internal battery voltage is low, it needs to be
replaced. Specific steps are as follows:
1. Press “power switch” to turn off power supply of LV display meter.
2. Unscrewing four screws on the LV display panel, and remove the panel.
3. Unscrewing the screw on the battery box and open the battery cover,
then replace the 9V battery. (Note the positive and negative polarity of battery)
