* 2 s after power-on and full display, the meter will enter normal measurement mode. In
case of internal EEPROM error or low voltage, "ErrE" will be displayed.
* Automatic power-off:
During the measurement, when the knob switch and keys are idle in the set power-off
time (5-30 minutes), the "automatic power-off" function of the meter will be activated
to save energy. After the automatic power-off function is activated, clicking any key or
turning the knob switch may achieve "automatic wakeup" of the meter.
From the last 1 minute of automatic power-off time, the APO symbol will flash; from the
last 40 s, 20 s or 10 s, if the "BEEP" in the set item is "ON", the beeper will sound three
times ("beep, beep, beep"); in sleep mode, the beeper will sound once ("beep"). During
the flashing of the APO symbol, pressing any key can cancel the automatic power-
off function (at that time, APO symbol will appear as normal), and will not activate the
original function of the key.
