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.
