4.4 Metrological configuration mode
A special operational mode is available which may be useful when making configuration changes to an
instrument already in service. Most changes would not require this, but if multiple changes are being
made and there could be dependencies between those changes (in particular if the instrument would
measure incorrectly if it received a volume pulse from the meter while the changes are still in progress â
only partially completed). The mode is called Metrological Configuration Mode. In this mode, input volume
pulses are queued but not processed, and Pressure and Temperature measurements are deferred.
Processing continues normally after you exit the mode, with the queued input volume pulses handled per
the new configuration.
You enter and exit the mode either through the HMI (L2.9 and L3.11 MET CONFIG), or through
MasterLink Software Application by setting/clearing item 1239.
Note: The mode will also be exited automatically on an exit from HMI mode (either explicitly or by
inactivity time-out) and likewise on a serial comm (MasterLink Software Application ) disconnect from
the instrument (either explicit or by inactivity time-out). (It will exit the mode on either HMI or Serial
exit, regardless of which was used to activate the mode.)
