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.
rcAL Calibration
point
nonE No calibration
PV Calibrate main Process Value input.
PV.2 Calibrate DC input, or PV 2.
1A.Hi Calibrate DC output high - Module 1
1A.Lo Calibrate DC output low - Module 1
2A.Hi Calibrate DC output high - Module 2
2A.Lo Calibrate DC output low - Module 2
3A.Hi Calibrate DC output high - Module 3
3A.Lo Calibrate DC output low - Module 3
I NPUT C ALIBRATION
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 400 Ω 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. FACt Restore factory calibration
GO Start calibration no Waiting to calibrate PV point
Select ‘ YES’ with or YES Start calibration
Wait for calibration to buSy Busy calibrating
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.
