CAL
Calibration
In this mode you can
1. Calibrate the instrument using a mV source -
rcAL or ref source
cal.
2. Offset the calibration to account for errors in actual sensor
measurement and a ref sensor -
UCAL or user calibration
3. Return to factory set calibration -
FACT or factory set calibration.

INPUT CALIBRATION
For ‘CAL’ = ‘PV’, or ‘PV.2’, the following parameters apply.
PV
PV Calibration Value
IdLE
Idle
mv.L
Select 0mV as the calibration point
mv.H
Select 50mV as the calibration point
V 0
Select 0Volt as the calibration point
1. Select calibration value
V 10
Select 10V as the calibration point
2. Apply specified input
CJC
Select 0
o
C CJC calibration point
3. Press
to step to ‘GO’ rtd
Select 400Ω as the calibration point
HI 0
High impedance: 0Volt cal’n point
HI 1.0
High impedance: 1.0 Volt cal’n point
See Note below.

complete.
donE
PV input calibration completed
FAIL
Calibration failed
Note. When a DC input module is installed for the first time, or there is a requirement to change one,
then the microprocessor in the controller needs to read the factory calibration data stored in the module.
Select ‘FACt’ as the calibration value. Step to ‘GO’ and start calibration.
