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).

• Model 8969 Strain Unit
The following device can be connected to the module.
• Strain Gauge Transducer (Not available from Hioki)
• Connect L9769 or 9769 Conversion Cable to the strain gauge
Measuring vibration or displacement with a strain gauge transducer
Connect a strain gauge transducer to a connector on Model U8969 Strain Unit via Model L9769 Conversion Cable; Mod-
el 8969 Strain Unit via Model 9769 Conversion Cable.
The instrument describes Model U8969 as “8969”.
Connect the strain gauge transducer to a
measurement object.
Connecting the L9769
1
Insert Model L9769 into a connector of
Model U8969 with the slot of the plug
aligned with the outward indentation of
the connector.
2
Insert the plug into the connector until
they are locked together.
3
Connect Model L9769 to the strain
gauge transducer.
4
Connect the strain gauge transducer to
a measurement object.
Example: Connecting the strain gauge transducer to Model U8969 Strain Unit via Model L9769 Con-
version Cable
Required items:
