Hold Reading

The ‘Hold Reading’ option allows the user to freeze the currently displayed reading. This allows it to 
be manually recorded or moved away from the sample point. Once activated, press the soft-key 
‘Hold’ and the readings are fixed until the ‘Hold’ key is pressed again or by storing the reading.

The current mode of operation can be identified by the status of the soft-key which is inversed whilst 
in the hold phase. When hold is active the ‘Pump’ and ‘Peak’ keys are disabled.
