ACV750V frequency response:
（50～200）Hz.
4. Operating Instruction
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.
2. Push the power switch button "POWER".
3. Selected the voltage under test according to
measurement needs (1000V/2500V)
4. Selected the range switch according to
measurement needs
5. L
：
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.
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.
7. If the MSD displays "1", it means over range, please set a higher range to read data.
5. Insulated Resistance Measurement
6. Safety Precautions
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.
2. When measuring, please check if the selected testing voltage accords with the voltage supplied by LCD or panel.
3. The symbol
“ ”
indicates lack of battery power, please replace batteries accordingly.
4. When measuring, unstable reading may caused due to environmental interference or unstable insulated material. Please
connect “G” terminal to the shied side of the tested object to get a stable reading.
5. Keep the instrument away from humid place and avoid direct sunlight in case the life of LCD Monitor is affected.
6. To guarantee the safety of measurement, the silicone rubber cable line is used. Don't replace the measuring line at random.
7. When the external adapter is used, it will disconnect the battery power automatically. Please don't charge the batteries at this
time. Note: Please select
（ ）
power supply mode.
