5. Electrical connections
5.3.2 Resistance thermometer (RTD) and resistance sensor
It is possible to connect an RTD resistance thermometer to
DIN EN 60 71 or any resistance sensor in a 2-, 3- or -wire
connection method. Configure the input of the transmitter to match
with the actual method of connection used.
Otherwise you will not fully exploit the possibilities of connection
lead compensation and, as a result, possibly cause additional
measuring errors (see item 6 'Configuration').
5.3.3 Thermocouples (TC)
Make sure that the thermocouple is connected with the correct
polarity. Only use thermal or compensation cable in accordance with
the connected type of thermocouple should the lead between the
thermocouple and the transmitter have to be lengthened.
Configure the input of the transmitter in accordance with the type of
thermocouple and cold junction that is actually used.
Otherwise false measurements will be given.
(See section 6. Configuration).
When connecting a thermocouple with internal cold junction, the
terminals  +  are to be shorted (shorting jumper / shorting bar).
