4.4 HOLD function
When the HOLD function is active, the word “HOLD” appears at the bottom of the LC display on the line where
the date and time are normally displayed.
The display is frozen and shows the values that were either last measured or last calculated at the time the
ON/OFF key was pressed. All functions such as data logging, data capture, probe adjustment, etc. are also
frozen. Likewise, communication with the ROTRONIC HW4 software is frozen. The HP23 menu can still be
used to change the display mode, but the values are not updated. The HOLD function is automatically ended
whenever the instrument is turned off. The values that were displayed while the HOLD function was active are
not memorized and are lost.
The HOLD function is not available when the Aw Mode is enabled. Enabling the Aw Mode automatically ends
the HOLD function.
WARNING: when the HOLD function is active, functions such as data logging and probe adjustment from the
keypad should not be used because both the measured and calculated values are no longer updated.
