Instrument Calibration
50 515 BR03 - 15 August 2021
AUTO COMP The batch automatic overrun compensation allows the instrument to
automatically compensate for any consistent overrun at the end of the
batch. Overrun is typically due to the slowness of a valve to close or a
pump to stop on receiving a signal from the batch controller and results
in the delivered quantity being greater than the entered preset.
In calculating the amount to be compensated for the instrument uses the
average overrun from the last three batches. An overrun of more than
20% is considered invalid and will not be included in the calculations.
Press or to select ENABLE or DISABLE.
No-SET BATCH To provide faster access to commonly used preset values a number of
batch presets can be preprogrammed into the instrument. This parameter
allows the number of batch presets to be entered.
Press or to select a number between 1 and 20.

Enter the commonly used preset values for quick access via the front
panel.
Enter the value in the engineering units of the batch preset.
DIRECT ACCES If the direct access is enabled then the operator is able to enter edit mode
for the batch preset and flow parameters directly from the main menu by
holding the
key while viewing the preset. If disabled, the changes
can only be made from within the calibration set mode (or via serial
communications, see below). Select the direct access mode as required.
Press or to select ENABLE or DISABLE.
Modbus Accessible Parameters
The following PARAMS menu item(s) are also accessible via Modbus communications. For
a complete Modbus parameter listing, refer to
Instrument Configuration Parameters on
page 83.
P-CTRL SP Preset process control signal setpoint. This setpoint is only available for
LOCAL control mode.
Enter the value in the engineering units of the assigned variable.
If LOCAL control mode the live P-FLOW value is now shown to give immediate feedback
without leaving calibration set mode.
P-FLOW SP Preset Loop/Process flowrate setpoint. This setpoint is only available for
LOOP control and TUNE modes. The value of the setpoint must not be
greater than the process flow range (P-FLOW RANGE).
