Please wire so that the main unit is not tugged by the signal input cable .
If the main unit is pulled, there is a danger where the device will tip over .

Input cable
This device conforms to the EMC directive when the core is attached to the input cable.
Please attach the supplied core to the input cable as shown in the figure below.
* Even without a core, measurement accuracy is not affected.
When installing more than one (3 to 4 pcs .) at
the same time
Screw terminal
Recommended tightening torque of screw terminal is max. 6kgf/cm.
If the thermocouple tends to come off due to the use of a thin-type thermocouple, replace it with the supplied
M3.5 flat screw.

Compensating lead wire
Ex: The current is converted to the voltage using
the shunt register .
For 4 to 20mA current input, install 250 ohms
(0 . 1 %) resister for converting 1 to 5V .
