4 Operating Instruction
4.1 Open the back cover of
the battery case and put
the 5# batteries (8) (see
the pictures). Be sure the
batteries are placed in
correct polarity.
4.2 Push the power switch
button "POWER".
4.3 Selected the voltage under test according to measurement needs
(1000V/2500V)
4.4 Selected the range switch according to measurement needs
4.5 High voltage output terminal, which connects to tested circuit by special
cable.
G: Protection terminal, which connects to the protection terminal of
three electrodes and eliminate the leakage effect of the tested surface.
E: Ground terminal, which connects to the GND of the tested objects.
For example, connects to the metal shell of tested polarity, transformer
core, the cable shield, the earth and the artificial discharge wand.
4.6 Press the test switch, and the test starts. The reading is available when
the display value becomes stable. After the reading is finish, release the
test switch.
4.7 If the MSD displays "1", it means over range, please set a higher range
to read data.

Insulated Resistance Measurement
6 Safety Precautions
6.1 Pay attention to safety! L is high voltage
output terminal! E terminal must be connected to ground; the tested
object must be removed from power network and could only be
connected or disconnected after artificial discharge to prove safety.
During measurement, try to avoid high voltage sparking discharge.
Frequent sparking will cause damage to the instrument.
6.2 When measuring, please check if the selected testing voltage accords
with the voltage supplied by LCD or panel.
