Measurement Ranges
Ranges in the following table are expressed in degrees C. The user can select either
0.1 or 1.0° (C or F) for the output data format.
If the 0.1° format is selected, the decimal point is implied (i.e., a reading of 1234
should be interpreted as 123.4° ). The internal CJC data is reported in the same units
as the TC output.
All TC output data is in signed integer format except as noted for Type B (see below).
NOTE: If the TC is open, then the warning bit is cleared and the out-of-range bit is
set. If it is over range, then the channel’s output data word is always 7FFFH; if it is
under range, the channel’s output data word is always 8001H. These are the
possible highest and lowest values.
