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 for PV1 and up to 8 linearization points may be selected for PV2. See page 46 for details.
Scaling the Meter (
SCALE
)
The strain gauge input (e.g. 0-100 mV) 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.
Dual-Scale Application
The analog input can be displayed in two different scales, by enabling the dual-scale feature in the
Setup Input
menu,
see page 25.
To enable the dual-scale feature you must select it in the Input selection menu.
Scaling the Input for PV1 (
SCAL 1
)
Scaling the Input for PV2 (
SCAL 2
)
Error Message (
Error
)
An error message indicates that the calibration or scaling process was not successful.
After the error message is displayed, the meter reverts to input 2 during calibration or scaling and to input 1 during
internal calibration, allowing the appropriate input signal to be applied or programmed.
The error message might be caused by any of the following conditions:
1. Input signal is not connected to the proper terminals or it is connected backwards.
2. Wrong signal selection in
Setup
menu.
3. Minimum input span requirements not maintained.
4. Input 1 signal inadvertently applied to calibrate input 2.
Minimum Input Span
The minimum input span is the minimum difference between input
1 and input 2 signals required to complete the calibration or
scaling of the meter.
For instructions on how to program
numeric values see Setting Numeric
Values, page 23.
