ELECTRICIAN’S MULTIMETER
OPERATING INSTRUCTIONS
If the battery voltage is low when the device is turned on, “
” symbol will appear on the
screen. User needs to replace batteries in time before use.
Please also pay special attention to the warning sign “
“ beside the test lead terminals, which
indicates that the tested voltage or current must not exceed the values listed on the device.
SLEEP MODE AND AUTO POWER OFF
If there is no operation for 15 minutes, the meter will automatically shut down to save power.
Before the auto shut-down, the buzzer will make five consecutive beeps and one long beep
and then enter the sleep state. Pressing any button to exit sleep mode, and the buzzer will beep

button and turn on the meter, the symbol disappears on the LCD with three beeps. Restart
the meter to restore the Auto-off function.
BUZZER WARNING
Input AC/DC
voltage >1000V: buzzer warning and red indicator is on, high voltage symbol
appears, indicating that the range is at its limit.
•
Current >10A: buzzer warning and the red indicator is on, indicating that the measured
current is relatively large, and the measurement time should be controlled.
•
Low battery detection: when the battery is lower than about 4.5V±0.1V, the low battery
symbol “
“ appears.
DC VOLTAGE MEASUREMENT
1. Switch the function selector to
V
position (range: 600mV/6V/60V/600V/1000V).
2. Connect the common test lead to COM terminal, then insert the red test lead into the to
