Sabre P PD603 Low-Cost Process Meter
Instruction Manual
10
Programming the Meter (
prog
)
The meter may either be scaled (
ScAL
) without
applying an input or calibrated (
Cal
) by applying an
input. The meter comes factory calibrated to NIST
standards, so for initial setup, it is recommended to
use the (
ScAL
) function.
The Program menu contains the Scale (
ScAL
) and the
Calibrate (
Cal
) menus.
Process inputs may be scaled or calibrated to any
display within the range of the meter.
Scaling the Meter (
ScAL
)
The process inputs (4-20 mA and
±
10 VDC) can be
scaled to display the process in engineering units.
A signal source is not needed to scale the meter;
simply program the inputs and corresponding display
values.
For instructions on how to program
numeric values see
Setting Numeric
Values
, page 9.
Error Message (
; rr
)
An error message indicates that the calibration or
scaling process was not successful.
After the error message is displayed, the meter
reverts to input 1, allowing the appropriate input
signals to be applied.
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.

Calibrating the Meter (
Cal
)
The meter can be calibrated to display the process in
engineering units by applying the appropriate input
signals and following the calibration procedure.
The use of a calibrated signal source is required to
calibrate the meter.
