3.3 Hold and delay-hold function
The data hold mode makes the meter stop updating the LCD panel. This mode
can be nested in most of the special modes. In auto scanning mode, the HOLD
key is not available. Enabling hold function in automatic mode makes the meter
switch to manual mode. Hold function can be cancelled by changing the
measurement mode, pressing RANGE, or push HOLD again.
The delay-hold function is enabled when HOLD key is pressed larger than 2
seconds. When delay-hold function is entered successfully, the meter will stop to
update the LCD data after six seconds delayed. During the six seconds waiting,
the HOLD symbol on LCD panel will be blinking.
