Programming the Meter (
prog
)
The
Program
menu contains the
Scale
and the
Calibrate
menus.
For strain gauge and load cell applications it is
recommended to calibrate
the meter using the sensor as
the input and with ratiometric operation enabled to compensate for small variation in the excitation
voltage.
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 millivolts. The calibration equipment is
certified to NIST standards.
Use the
Scale
menu to scale the input (e.g. 0-100 mV). A calibrated signal source is not needed to
scale the meter.
The PD6100 is a single input meter with dual-scale capability.
If the dual-scale feature is selected in the
Setup
menu, the
Scale 1
and
Scale 2
menus are enabled for
PV1 & PV2 respectively.
The process inputs may be calibrated or scaled to any display value within the range of the meter.
Program Menu for Single Scale Process
Program Menu for Dual-Scale Applications
Additional parameters, not needed for most applications, are programmed in the
Advanced
Features
menu; see Advanced Features Menu, page 43.
Calibrating the Meter with Strain Gauge/Load Cell (
Cal
)
To scale the meter without a signal source, refer to
Scaling the Meter (
SCALE
), page 29.
The meter can be calibrated to display the process variable in engineering units by applying the
appropriate input signal and following the calibration procedure.
The use of a calibrated signal source is strongly recommended to calibrate the meter.
Warm up the meter for at
least 15 minutes before
performing calibration to
ensure specified accuracy.
