Using the Power Down Timer
The power down timer turns off the tester after a selected
period of inactivity.
Halfway through the timer period, the tester beeps, the
screen dims, and the tester enters a low-power mode. Thirty
seconds before the timer reaches zero, the tester beeps
again to alert you that it is about to turn off. Pressing any
key restarts the timer.
If the timer is disabled, the screen dims after 30 minutes of
inactivity to help conserve battery power.
Note
The power down timer is inactive when the ac
adapter is connected or when the USB or RS-232
serial port is active.
