Channel 0 Status
(1)
(1) This parameter is in Byte and has the following structure:
Bit 0 = Fault; Bit 1 = Calibration; Bit 2 = Low Alarm; Bit 3 = High Alarm; Bit 4 = Low Low Alarm; Bit 5 = High High
Alarm; Bit 6 = Underrange; Bit 7 = Overrange

Cold Junction Status
Channel 0
(2)
(2) Cold junction status is defined below. When a fault is detected, the Cold Junction Temperature is set to zero (thus,
a word value of 0xC000 indicates that the cold junction is enabled, but no thermistor data is available).
00 = No fault; 01 = Underrange; 02 = Overrange; 03 = No thermistor detected
