with the meter together for further reference.
Precautions：
To avoid possible electrical shock or personal injury, please pay
extra attention on those symbols indicated on the manual and
corresponding illustration.
Warning：Improper or careless may result in
personal injury or even death.
Caution：Improper or careless may result in
damage to the meter or other

Warning
⚫Set the function switch and function key at the
proper position and function before measuring.
⚫Remove test leads from the circuit being tested
before switching functions.
⚫Do not apply more than the rated range of function
specified.
⚫Check and make sure the meter or test leads are
intact before use. Do not use the meter or test
leads if they appear damaged.
⚫When using the test leads, always keep hands
behind the guard ring.

- 3 -
⚫When measuring resistance, first switch off the
power to the circuit under test, and verify that the
voltage is zero.
⚫Keep the meter dry. Do not use it with wet hands
or if there is moisture in or on the meter.
Warning

Caution
⚫Do not use the meter near equipment emitting noise
or in environments with sudden temperature
changes. Unstable or inaccurate reading may occur.
⚫When finished measurement, turn the function
switch back to OFF position to turn off the meter
completely. There is minor power exhaustion if the
meter is power off by auto-power-off function.
⚫If it is necessary to clean the meter, use a soft cloth.
Never use solvents.
⚫Do not expose the meter to direct sunlight, extreme
temperatures or moisture.
⚫Do not attempt to open the case except the battery
door for replacing battery or fuses.
⚫Any impact or drop of battery will result leakage
afterwards and possibly damage the meter. Thus,
don’t use those batteries if occurred.
⚫Take the battery out of the meter if it will not be used
for several weeks or storage.
⚫When symbol displays, replace the battery
immediately.

1. Set rotary switch to position.
2. Plug black test lead into the COM terminal and red test
lead into the V terminal.
3. Connect test leads to the circuit to be tested. Allow time
for the value to stabilize and then read the AC voltage
measurement on the LCD.
4. When input exceeds 1010V, “OL”& high voltage alert
symbol display and buzzer is on to alarm a high voltage
presents.
5. The corresponding frequency of the AC voltage value
syncs displaying on sub-display. It may not display
properly if the input AC voltage is too small to be
detected.
6. When finished, turn rotary switch to OFF position to turn
off the meter.
