Calibration
Temperature Indicators and Recorders
This procedure suits Temperature Indicators/Recorders no matter
if the sensor is an RTD or a thermocouple. The instruments input
signal is simulated using MC5P and the output reading is entered
into MC5P.
Required modules
•
The
ET
module for simulating the temperature sensor. The
Base Unit takes care of entered output signal.
Preparations
1. Connect suitable terminals in MC5P to
the input connectors of the indicator/
recorder.
2. If the sensor to be simulated is a ther-
mocouple, select one of the following
reference junction methods:
•
The internal Reference Junction
module is in use.
•
The reference junction is fixed to
0°C.
•
The reference junction tempera-
ture is entered.
•
The reference junction tempera-
ture is measured externally using
an RTD connected to the RTD ter-
minals.
See Part C for additional information
concerning the reference junction meth-
ods.
3. If the sensor to be simulated is an RTD,
the used wiring system depends on the
instrument to be calibrated. Remember
to only use the two leftmost RTD termi-
nals in MC5P.
4. Test the connections in Basic Mode if
needed. To quickly configure the Basic
Mode’s windows, go to Calibration
Mode, select the instrument to be cali-
brated and the Function Key
C
/
Cali-
brate
but immediately return to Basic
Mode.
