CAUTION
When adjusting the temperature with such as an air conditioner, take measures to prevent the
product from being exposed directly to the air.
Right after the product is started, the measuring temperature may exceed the specified
tolerance. Warm up the product for at least 30 minutes before use.
[Example of thermocouple connection]
The following figure shows an example of thermocouple connection. Connect the positive and negative
terminals of each thermocouple to the positive and negative sides of each thermocouple input channel.
Thermocouple connection
[Example of shielded thermocouple connection]
The following figure shows an example of shielded thermocouple connection. Use shielded
thermocouple cable if the distance between the temperature measuring place and the product is
long or if you want to provide better protection from noise. Connect the positive and negative
terminals of each thermocouple to the positive and negative sides of each thermocouple input
channel. Then, connect the analog ground of this product to the shielded braid and earth gound the
shielded braid.
