Caution: Failure to fully open terminal jaws before removing wire may permanently damage instrument.
Wiring Procedure
1. Remove 0.5 - 0.625 in. (13-16 mm) of insulation from wire end.
2. Press the orange terminal lever downward with a small screwdriver to open terminal jaws.
3. Insert exposed (non-insulated) wire end in terminal hole until it bottoms out.
4. Release orange terminal lever to secure wire in place. Gently pull on each wire to ensure a good connection.
Wiring Removal Procedure
1. Press the orange terminal lever downward with a small screwdriver to open terminal jaws.
2. When fully open, remove wire from terminal.

Wiring Tips:
• Do not route sensor cable in conduit containing AC power
wiring. Electrical noise may interfere with sensor signal.
• Routing sensor cable in grounded metal conduit will help
prevent electrical noise and mechanical damage.
• Seal cable entry points to prevent moisture damage.
• Only one wire should be inserted into a terminal. Splice
double wires outside the terminal.
• Sensor cable may not be extended over 100 ft.
Sensor Selection
Select the sensor with a range closest to your process minimum and
maximum values.
• CDCE-90-001 (0.01 cell): 0.055 to 100 µS (10 kΩ to 18 MΩ)
Use the CDCE-90-001 for all resistivity requirements
• CDCE-90-01 (0.1 cell): 1 to 1000 µS
• CDCE-90-1 (1.0 cell): 10 to 10,000 µS
• CDCE-90-10 (10.0 cell): 100 to 200,000 µS
• CDCE-90-20 (20.0 cell): 200 to 400,000 µS
