Electrical and Temperature Module (ET module)
The ET module is spe-
cially designed for tem-
perature instrument
calibration needs. It is
not however restricted
to only temperature in-
strument use because
it can also generate
voltage, frequency and pulses. Additionally the ET module is able
to sink current.
Measuring capabilities:
• Low Voltage measurement and T/C measurement using ei-
ther the internal reference junction or the Low Voltage connec-
tors.
• 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, frequency and pulse generation.
• Current sink.
Reference Junction Module
The T/C measurement/
simulation internal ref-
erence junction is an
optional addition to the
ET module. It is spe-
cially designed for
MC5-IS and therefore
best suited for reference junction compensation when calibrating
thermocouples or instruments connected 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 MC5-IS
before connecting the wires/plug to the Reference Junction Mod-
ule. Make sure to connect the wires/plug as the polarity is indicated
on the Reference Junction Module. Remember to tighten the fas-
tening 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.
