4.3C Setting Up the Analogue Retransmission

All analogue retransmission outputs are calibrated to the cell thermocouple input range. The input must be set up for a type K
thermocouple, with °C display units, to give the widest span (and hence the maximum accuracy), as follows:

Make a note of the retransmission range(s) and then reset it for 4 to 20mA
operation – see Section 6.2 in ZMT/0011.
Set the number of retransmission outputs being used (2 maximum on basic
analysers).
