Calibrating The Meter With Strain Gauge/Load Cell (Cal) - Helios PD2-6100 Instruction Manual

Helios PD2-6100 Strain Gauge, Load Cell, and mV Meter
Calibrating the Meter with Strain
Gauge/Load Cell (Cal)
To scale the meter without a signal source, refer to
Scaling the Meter (SCALE) on page 30.
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.
Note: Inputs for the above example are:
Input 1: 0.00 mV; Display 1: 0.000 mV
Input 2: 150.00 mV; Display 2: 150.000 mV
Warm up the meter for at least 15 minutes before
performing calibration to ensure specified
accuracy.
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 Multi-Point Linearization
(Linear) on page 45 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.
For instructions on how to program numeric values
see Setting Numeric Values on page 27.
