3000 Counts Smart DMM

1.6.2 Sleep output

The meter enters sleep mode after auto power-off or push SEL key to last for 2s.

The SLEEP pin asserts low (-3V) in the sleep mode, and asserts high (+3V, not 0V)

after re-power on.

1.6.3 Re-power on

After auto power-off is active, pushing any of the push function or changing the

measurement function can turn on the meter again. If the meter is re-powered on

by changing measurement function, the saved state is cleared. If the meter is

re-powered on by push functions, the chip restores the saved state and enters

HOLD mode. The LCD displays the saved value except for the auto scan mode.
