● Auto Hold Measurement mode
D-52/53/54/55
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.
