In the setup setting display mode

[C01]

, press the [<]

•

[ ]

•

[ ] key

to set the lower display to select a desired PV range type.

>> When no keys are pressed for 2 sec. or longer, the flashing of the

numeric value is stopped to set the currently displayed value.

●

SP setup

While the PV/SP is displayed in the operation display mode, press the
[<]

•

[ ]

•

[ ] key to change the SP in the lower display.

>> When no keys are pressed for 2 sec. or longer, the flashing of the

numeric value is stopped to set the currently displayed value.
SP can be set in the parameter setting display mode.

Handling Precautions

· The accuracy of the B thermocouple is ±5%FS for a range of

260°C or less, and ±1%FS for 260 to 800°C.

· The accuracy of the PLII thermocouple(CO1 No.19) in the

range of 0 to 32˚F does not meet the indication accuracy

specified in the Specifications.

· For ranges with a decimal point, tenths are displayed on the

line underneath point.

· Make sure to set the correct number in setup display C01,

according to the type and range of the sensor used. If the

setting is wrong, problems such as large temperature errors in

the output may occur.

Cleaning:

When wiping out the C15M, use the soft and dried cloth.

Parts replacement: Do not replace the parts.
Fuse replacement: When replacing the fuse for the power supply wires, make

sure that the replacement fuse complies with all applicable
safety standards.

Recommended cables:

For thermocouples:

Connect thermocouple wires to the
terminals directly. When a thermocouple is
connected to terminal block, or wiring
distance is long, connect the wire via a
shielded compensating lead wire.

For input/output other than thermocouples:

Use a JCS 4364 instrument cable or
equivalent. If electromagnetic induction
noise is comparatively low, a shielded
multiconductor microphone cord (MVVS)
may be used.
