General
Electrical and Temperature Module (ET module)
The ET module is specially designed for
temperature instrument calibration needs.
It is not however restricted to only tempera-
ture instrument use because it can also
generate
voltage
,
current
,
frequency
and
pulses
.
Measuring capabilities:
•
Low Voltage measurement and T/C
measurement using either the inter-
nal reference junction or the Low Volt-
age connectors.
•
Resistance and RTD measurement.
Generation/simulation capabilities:
•
T/C simulation using either the internal reference junction or
the Low Voltage connectors.
•
Resistance and RTD simulation.
•
Voltage, current, frequency and pulse generation
Reference Junction Module
The T/C measurement/simulation internal
reference junction is an additional part of
the ET module. It is specially designed for
MC5P and therefore best suited for refer-
ence junction compensation when calibrat-
ing thermocouples or instruments con-
nected to a thermocouple.
The Reference Junction Module is suited
for all standard T/C plugs and stripped
wires. Open the fixing screw on the left side
of MC5P before connecting the wires/plug
to the Reference Junction Module. Make
sure to connect the wires/plug as the po-
larity is indicated on the Reference Junc-
tion Module. Remember to tighten the fastening screw when the
wires/plug are connected. Hand tightening is adequate. Do not pull
out the wires/plug without first opening the fixing screw. Otherwise
you might damage the contact surface of the connectors.
T/C measurement and simulation may also be done without the
internal reference junction by using the Low Voltage terminals in
the ET module. Then the reference junction arrangements have to
be done outside MC5P and the correct reference junction settings
