Auto Hold Measurement mode
Auto Hold Measurement mode maintains the display of
the value measured when the meter automatically
judges that the measured value has stabilized. Press the
MEAS key with the initial screeen displayed to make
HOLD blink on the display. When the measured value
becomes stable,
HOLD will stop blinking and remain
displayed, and the measured value will remain
displayed. To clear the hold status or
stabilized value
(when
HOLD is blinking), press the MEAS key.
