Input Calibration Method (
InCAL
)
There are two methods of calibrating (or scaling) the display to show the correct engineering units.
•
Use the
Scale
menu to enter the scaling without a signal source.
•
Use the
Calibrate
menu to apply a signal from a signal source.
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 Scale and Calibrate
accordingly under the Number of Points
(
nopts
)
menu selection prior to scaling and calibration of the
meter, see page 53 for details.
Scaling the Meter (
SCALE
)
The process inputs (4-20 mA and
10 VDC) can be scaled to display the process variable in engineering
units. A signal source is not needed to scale the meter; simply program the inputs and corresponding
display values.
