6.3.3 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.
