CJC Configuration | CJC Enabled on Channel 1 | CJC Disabled on Channel 2 |
|---|---|---|
Channel Offset = 0 CJC Mode = None 4 | Not a valid setting Enable CJ Compensation is not available | No compensation applied |
Channel Offset = 0 CJC Mode ≠ None | Use thermistor readings for compensation 3 | No compensation applied |
Channel Offset ≠ 0 CJC Mode = None | Not a valid setting Enable CJ Compensation is not available | Use the channel offset value for compensation |
Channel Offset ≠ 0 CJC Mode ≠ None | Not a valid setting Selecting Enable CJ Compensation forces

1 The CJC Enable feature only applies to the thermistors.
If the CJC Mode is None, the Enable CJ
Compensation checkbox is not available and is forced
to be cleared. Selecting Enable CJ
Compensation disables CJ Compenstation
Offset and sets it to 0.00 ℃
in the profile.2 The CJ Compensation Offset
parameter is available when the Enable Cold Junction
Compensation checkbox is cleared.3 If a thermistor is not detected at any specified
channels, the produced cold junction data indicates an error
(0xC000) and no compensation will be applied. Under range is
reported as 0x4000, and over range as 0x8000.4 CJC Mode = None implies that Cold Junction
(CJ) Compensation Mode is set to Average
Channels and no channels are selected for
averaging. | ||
