<HOLD> - Key
Function - 1 -
With the <HOLD> key a measured value may be "frozen". After pressing the key
<HOLD> without further action by the user, the measured value is collected during 15-
17 seconds and then displayed. When the conditions are stable this data collection may
be reduced by earlier pressing the key <ENTER>. The display shows "on hold". This
“frozen” value will be displayed until - by pressing the key <SEND/ESC> - the
BlueMETER BASIC will return to the measuring mode.
Function - 2 -
When using the mode "REL.ZERO" and "ABS.ZERO" the actual measuring value can
be accepted by pressing the <HOLD> key.
