Measuring point list and monitoring
General information on measuring point list:
• Measured points are entered in the measuring point list at the preset time interval.
• If one (or more) entries appear during the refilling time, one measured point is entered
immediately after the refilling. The time reference otherwise remains unchanged,
however.
• If the stop time occurs within the refilling time period, after filling one measured point is
entered and only then the determination is stopped.
• The measuring point list always includes the values of time and volume. If monitoring
of measured values and/or temperature is active, the corresponding values are
entered too.
• The "mess." column shows a message if a limit value was exceeded in the last time
interval, see example below. "* " is used to mark if dosing was interrupted, e.g. owing
to refilling, action "wait" or "hold" on limit value violation or manual <HOLD>.
• The volume of the last measured point entry can differ from the final volume as time
may have elapsed between the last entry and the actual stop. The final volume is
available as variable C41 and can be used to calculate results.
