Measuring point list and monitoring
• Measured points are entered in the measuring point list at the preset time interval. The
input times represent the clock time. This must be distinguished from the dispensing
time: The dispensing time does not include any waiting times which can arise in
refilling, hold or wait as a result of limit value violations.
• If one (or more) entries occur in the time during refilling, one measured point is entered
immediately after the refilling. The time reference otherwise remains unchanged,
however.
• The measuring point list always includes the values "time" and "volume". If monitoring
of measured values and/or temperature is active, the corresponding values are also
entered.
• The "mess." column shows a message if a limit value was violated in the last time
interval, see page 53. "*" is also used in this column to mark when the dispensing was
interrupted: refilling, action "wait" or "hold" on limit value violation or manual .
• 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 end volume (C41)
can be used for calculations.
The values from the measuring point list can be shown graphically.
Example: Profile of the pH value during a dispensing with the "wait" action.
Curve pH vs. time ("meas crv") Curve volume vs. time ("curve")
