Mastech MS8233E - Electrical Specification

● Auto Power- OFF. : If the meter is idle for 15 minutes (idle time), the meter
automatically turns the power off. After auto power-off, pushing any of the push
button or changing the rotary switch can turn on the meter again.
NOTE: （1） After auto power off in the AC mode, if changing the rotary
switch to the DC mode, the Re-power on if disabled.
(2) The meter enters sleep mode after quto power off. If press
“HOLD” push button to re-power on in the sleep mode, the auto
power off function is disabled.
