1
Strip insulation from the thermocouple
wires as shown at the left.
Stripping length: approx. 10 mm
2
Push the blade of a flat screwdriver
into the button on the terminal block of
the module.
3
Insert each thermocouple wire into the
appropriate terminal hole while press-
ing the button.
Confirm proper polarity.
4
Release the button.
The thermocouple is connected.
5
Attach to the measurement object.
To remove the thermocouple
Hold the button while pulling the ther-
mocouple wire out.
Required item:
Thermocouple, Ferrite clamp-on choke (8967’s option),
flat-blade screwdriver (2.6-mm blade)
Recommended wire:
Compatible wire:Single-strand thermocouple wire, 0.4
to 1.2-mm diameter
Stripping length:10 mm
If surrounding equipment is affected by noise, coil the ther-
mocouple several times and then attach the included ferrite
clamp-on choke (as seen in the diagram to the right).
