6.8 S4000CH Command Register Details
6.8.1 Analog (00h)
A read returns a value, which is proportional to the 0-20 mA output current. The current is
based on a 16-bit value. The scaling is 0 - 65535 decimal which corresponds to 0 - 21.7 mA.
6.8.2 Mode (01h)
A read returns the present mode of the S4000CH.
A write command changes the mode to the requested mode. A data value of 08 will start
calibration mode if the unit is in the run mode. It also will go from cal check to cal mode.
A write command with the data value of 04 will put the unit in Cal Check Mode if there are no
errors or alarms.
Exception: Returns an Exception Code 01 (illegal function) if an illegal write is requested.
