. Other Functions
1.
Automatic power off
After the meter is stopped for 15 minutes, it will cut off power automatically (power off), and then enter the dormant
(power off) state. The built-in buzzer will send out warning tone in one minute before it powers off. If you want to restart
power(power on), please press the power switch. If you want to cancel antomatic power-off, please press “REL” key over 2
seconds until the RS232 symbol appears. Meanwhile the “APO” symbol will be also turned off.

The initial state of the meter is the DC voltage automatic measurement mode, which shows the symbols of
“DC”“AUTO”“APO”. Press “RANGE” is to select manual range mode; Press “MAX/MIN” once to show the Max
measurement value. Press “MAX/MIN” again to show the Min measurement value. Press “MAX/MIN” over 2 seconds is
to cancel the measurement of the MAX/MIN value.
