Step 2. Insert the top cable cover and bottom cable cover in the socket.
Secure the cable from the bottom cable cover with a cable tie.
Top cable cover (included)
Temperature sensor connectors

NOTE
Socket fixing screw tightening torque: 0.2 Nm to 0.25 Nm
The cable cover protects the terminal and cable fixing screw areas from static electricity, etc.
5 Reference junction compensation (CJC) when measuring thermocouple (TC)
Reference junction compensation is required when measuring the thermocouple (TC), and can be
switched between internal and external compensation with this module.
Internal reference junction compensation measures the reference junction temperature at the module
front panel.
When external compensation is set, it is necessary to externally perform 0°C reference junction
compensation.
NOTE
Perform measurement so that the temperature around the input connectors is stable.
If there is a rapid change in the surrounding temperature, wait until the module temperature stabilizes
(about one hour) and then start measurement.
Ensure that the input connectors are not directly exposed to wind.
Do not block the air holes of the front panel.
