Setting the power saving mode
To enable auto power- off, set this timer to any value from 1
to 99 minutes.
This feature is incorporated for power saving. The
instrument will automatically turn off after the specified
period of time, if none of the following happens within that
period:
• A key on the keypad is pressed
• A measurement function is changed
• The dynamic recording mode is activated
• The 1 ms peak hold mode is activated
• The auto power- off feature has been disabled in the setup
mode
• The output has been enabled (the annunciator is
displayed)
To reactivate the instrument after auto power- off, turn the
rotary switch to the OFF position and then turn it on again.
If the instrument is to be used for a long period of time, you
may want to disable the auto power- off feature. When the
auto power- off feature is disabled, the annunciator
will not be shown on the display. The instrument will
remain on until you manually turn the rotary switch to the
OFF position, or until the batteries run flat.
