Basic Operation
Power on/off
Turn the knob to the desired measurement position to turn the multimeter on. Turn the knob to the "OFF"
position again to turn off the power.
• Move the test probe away from the test point before turning the knob (shutdown).
• When the meter is used, turn off the power in time.
Automatic shut-down
If there is no button operation within the set 15 minutes, the meter will automatically shut down.
• Only the display of the main chip and LCD screen is turned off when the instrument is
automatically shut down, but there is still a certain leakage current.
• If it is not used for a long time, switch the knob to “OFF” position
Battery replacement
When the meter is in use and the low-voltage symbol appears in the upper right corner of the LCD screen,
the user should replace the battery as soon as possible.
When the meter is not used for a long time, take out the battery to prevent the battery from leaking and
damaging the meter.
Pay attention to the safety of the battery.
