To power OFF your LCR meter, press the power- on button
again.
Automatic Power-Off (APO)
Your LCR meter automatically turns off after 5 minutes
(default) if no keys are pressed. Pressing any key will turn
the LCR meter back on after it is powered off automatically.
The annunciator is shown on the bottom left of the
display when the APO function is enabled.
Enabling the backlight
If viewing the display becomes difficult in low- light
conditions, press for more than 1 second to activate the
LCD backlight.
To conserve battery life, a user- adjustable timeout controls
how long the backlight stays on. The default timeout is 30
seconds.
NOTE
You can change the power-on behavior of your LCR meter for subsequent
power cycles. See “Changing the initial power-on behavior” on page 54 for
more information on changing the LCR meter’s power-on setting.
NOTE
• To change the timeout period or completely disable the APO function,
refer to “Changing the auto power-off and backlight timeouts” on
page 71.
• If an
external power adapter is used, the APO function will be disabled.
