4.7.4 Calibration Parameters
CAL Basic Indicator Calibration Selected parameter
rCAL
Selected re-calibration
nonE
Idle state - no calibration performed
parameter PV.1 Main process value input selected
PV.2 Second analogue input selected (this will always be in module
position 3)
1A.Hi Module 1 DC retransmission high output (if installed)
1A.Lo Module 1 DC retransmission low output (if installed)
2A.Hi Module 2 DC retransmission high output (if installed)
2A.Lo
Module 2 DC retransmission low output (if installed)
3A.Hi
Module 3 DC retransmission high output (if installed)
3A.Lo
Module 3 DC retransmission low output (if installed)
If rCAL = PV1 or PV2 the following parameters
appear:
Calibration point Calibration value
PV PV or PV.2 calibration point IdLE Idle
mv.L mV low calibration point selected 0.000 mV
mv.H mV high calibration point selected 50.000 mV
V 0 0 Volt calibration point selected 0.000V
V 10 10 Volt calibration point selected 10.000V

FaiL Calibration failed
If rCAL = 1AHi to 3aLo (DC output module calibration) the following parameters appear:
cAL.L DC output calibration low point 0 0 = Factory cal. Trim value to give output = + 1V or +2mA
cAL.H
DC output calibration high point
0 100 = Factory cal. Trim value to give output = + 9V or +18mA
