Read Word 10 00-07 Underrange bits - these bits are set if the input signal is below the input channel's minimum range.
08-15 (10-17) Overrange bits - thesebits areset if 1), theinput signal is abovetheinput channel's maximum
range, or 2), an open detector is detected.
Read Word 11 00-01 Not used - set to 0
02 Reserved
03 Powerupbit - this bit is set (1) until configuration data is received by the module.
04-06 Critical Error bits - If these bits are anything other than all zeroes, return the module to the factory
for repair
07 Unused - set to 0
08 (10) Calibration Range bit - set to 1 if a reference signal is out of range during calibration
09 (11) Calibration Done bit - set to 1 after an initiated calibration cycle is complete.
10 (12) Calibration Bad bit - set to 1 if the channel has not had a valid calibration.
