GT1-TS04T and GT1-TS04P Temperature Input Units
Section 5-3
Calibrating the GT1-TS04T
Use the following procedure to calibrate the GT1-TS04T. The DeviceNet and
the MULTIPLE I/O TERMINAL must be connected first.
Note The Temperature Input Unit is correctly calibrated before being shipped from
the factory, and calibration is not necessary for normal operation. Calibrate
the Unit only if absolutely necessary. OMRON is not responsible for the
results of any user-set calibrations. If the manual calibrations fail, clear the
calibration to restore the Unit to the default settings.

1.
Connect the external devices to the Temperature Input Unit that is to be
calibrated.
Use a calibrated thermocouple in a cold junction compensator and a com-
pensating conductor. If using an R, S, or B thermocouple, a K thermocou-
ple can be used instead. Set the cold junction compensator to 0
°
C, but
disable the setting (i.e., keep the contact open) until the bias compensation
described in step 10 is completed. Do not touch the Temperature Input Ter-
minal or the compensating conductors.
2.
Turn ON the power supply to all the Units of the MULTIPLE I/O TERMINAL,
including the Temperature Input Unit to be calibrated and the Communica-
tions Unit. Wait approximately 30 minutes until the internal temperature of
the Temperature Input Unit has stabilized.
3.
Connect the Configurator to the DeviceNet network and go online.
