-Hi Level Voltage at Input Device in conjunction
with CT1 of Voltage Output ModelInput voltage [V in] (High Level) is determinedby the following factors:• Power Source Voltage of CT1 [V]Option (Sold separately from 1 unit)
Meter Rubber Wheel of High Precision
Circumference adjusted
Comes with Certificate of Inspection
With extra charges, additional
documents can be issued, such as
Traceability System Diagram, andCertificate of Calibration Tool.

• Output Impedance of CT1 [R1]
• Input Impedance of Input Device [R2]

R2
V in = V x
R1 + R2

Meter Urethane Wheel
MRM110
Diameter of measuring part: 106.1 mm(1/3 m in circumference)
Outer circumference finishedwith urethane resin coating
Abrasion resistance* V,R1：Refer to SpecificationsAccessories

2 pieces of measuring wheel for meter are equipped as standard accessories.
Instead of those, 2 pieces of measuring wheel for yard are available.
Model : CT1-A Measuring wheel for meter x 2, 3P connector x 1
Please order type of measuring wheel.
Model : CT1-R Measuring wheel for meter x 2, 4P connector x 1 "-YP" should be added to the model number. (Ex.) CT1-3:10A-YP
Model : CT1

Measuring wheel for meter x 2

Measuring wheel for meter
MRM096
Diameter 106.1mm (Circumference 1/3 meter)
Surface material is Thermoplastic Rubber.

Measuring wheels are subject to slip due to wear after
prolonged usage.
They may cause measurement errors if not replaced on time.
Please periodically check the wheels for signs of deterioration.

Measuring wheel for yard
MRM097
Diameter 97.0mm (Circumference 1/3 yard)
Surface material is Thermoplastic Rubber.

Connection
Cable does not come with either CT1-A or CT1-R model.
Procure the cable that is appropriate for your installation environment, and the cable should be based on the specifications below:
For CT1-A models, 3-Pin cable equivalent to AWG16. For CT1-R models, 4-Pin cable equivalent to AWG20-22.
* 3P・4P connector (Please wire to terminal pins after disassembling.)• Model : CT1(Micro Switch output)
