Battery Saver (Sleep Mode)

The Meter enters "Sleep mode" and blanks the display if
there is no function change or button press for 20 minutes.
This is done to conserve battery power. The Meter comes
out of Sleep mode when a key is pressed or when the
rotary switched is turned.
To disable Sleep mode, hold down the blue button while
you turn on the Meter. Sleep mode is always disabled in
the MIN MAX AVG recording mode, AutoHold mode, or
when the insulation test is active.
