8.8 S4000TH Command Register Details
8.8.1 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.
8.8.2 Mode
(01H)
A read returns the present mode of the S4000TH.
A write command changes the mode to the requested mode. A data value of 08 starts
calibration mode if the unit is in the run mode. It also goes from cal check to cal mode.
Exception: Returns an exception code 01 (illegal function) if an illegal write is requested.
A calibrate command returns an exception code 01 (Acknowledge 05). The operation will take
a long time to complete.
