Instrument Calibration
515 BR03 - 15 August 2021 51
Inputs
If LOOP control or TUNE mode the live P-FLOW and DEVIATION values are now shown
to give immediate feedback without leaving calibration set mode.
PRESET BATCH Enter the batch preset quantity. This setpoint is only available for
PRESET batch mode.
Enter the value in the engineering units of the assigned variable.
O-RUN COMP Enter a fixed value batch overrun compensation that will allow the
instrument to 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.
This value is only used for batch overrun compensation when auto
overrun compensation is disabled.
Enter the value in the engineering units of the assigned variable.

INPUT
M-FLOW FINP1
P-FLOW FINP2
Frequency Input Channels 1 and 2 are assigned as flow inputs. Channel
1 is for measuring the main line flow and channel 2 is for the process line
flow.
SIGNAL FINP1
FINP2
Frequency input 1/2 signal type.
Press or to select COIL, NPS or PULSE.
DBNCE FINP1
FINP2
Switches and relays have metal contacts to make and break circuits. The
contact bounce introduces random signals into the circuit. The instrument
has a debounce circuit to eliminate this problem.
Note: When the debounce circuit is enabled, the maximum input
frequency for large amplitude signals is limited to approximately
500 Hz. For low amplitude signals, the maximum frequency can be
approximately 200 Hz.
Press or to select ENABLE or DISABLE.
