(1) Connecting Cables to the CH1 and CH2 Terminals
(Temperature Sensor Signal Input)
1.
Use a flat blade screwdriver to loosen the screws on the termi-
nal block.
2.
Insert a cable for input temperature sensor signal into the ter-
minal block, then tighten the screws (at a tightening torque of
0.25 N•m).
3.
Connect the terminal block to the CH1 or CH2 terminal.
The CH1 and CH2 terminals are not insulated from each other. Avoid
short-circuiting.

• The CH1 and CH2 terminals are not insulated from each other.
When measuring two measurement points having a potential
difference, use an electrically insulated sensor or another Pt
module, since measurements may be adversely affected.
• In case of external noise, wind the cable around the ferrite
clamp supplied as an accessory as shown below.
• Note that measurement may be adversely affected by external
noise or the electromagnetic environment when using a cable
longer than 3 meters.
