Programming the Batch Controller (
prog
)
It is
very important
to read the following information, before proceeding to program the meter:
•
The meter is factory calibrated prior to shipment to read in milliamps and volts depending on the input
selection. The calibration equipment is certified to NIST standards.
•
There is
no need to recalibrate
the controller when first received from the factory.
•
Use the
Scale
menu to scale process inputs (e.g. 4-20 mA). A calibrated signal source is not needed
to scale the meter.
•
Use the
Calibrate
menu to apply a signal from a calibrator or a flowmeter.
The
Program
menu contains the following menus:
1. Scale without a signal source
2. Calibrate with a calibrated signal source
3. Total time base & conversion factor
4. Grand total time base & conversion factor
5. Total reset mode for total & grand total
Note: The Scale and Calibrate functions are exclusive of each other. The meter uses the last function
programmed. Only one of these methods can be employed at a time. The Scale and Calibrate functions
can use up to 32 points (default is 2). The number of points should be set in the
Advanced Features
menu under the
menu selection prior to scaling and calibration of the
meter, see page 53 for details.
The process input may be calibrated or scaled to any display value within the range of the meter.
Additional parameters, not needed for most applications, are programmed in the
Advanced
Features
menu; see Advanced Features Menu, page 50.
Multi-Point Calibration & Scaling
The meter is set up at the factory for 2-point linear calibration. The number of points for multi-point
calibration/scaling is set up in the
Advanced
Features
menu. Up to 32 linearization points may be
selected. See page 53 for details.
