Section 6-4
Connecting the Devices
required for GRT1-TS2T
Adjustment
The following paragraphs explain how to connect the devices that must be
connected to the GRT1-TS2T for user adjustment. Wire the following devices
properly when adjusting the GRT1-TS2T.
■
Reference Voltage/Current Generator (STV) and Precision Digital
Multimeter (DMM)
Used to make adjustments at the upper limit and lower limit.
Prepare devices that can generate accurate 0 mV, 20 mV, and 50 mV volt-
ages. Use a precision digital multimeter that can measure the output voltage
and indicate when the voltage/current generator is not producing an accurate
voltage output.
■
Cold Junction Compensator (such as a ZERO-CON) and Compensating
Conductors
Used to adjust the bias compensation value.
The cold junction compensator (the ZERO-CON is used in following exam-
ples) is a device that maintains an accurate 0
°
C (32
°
F) temperature for ther-
mocouple sensors. Use a cold junction compensator compatible with the
sensor being adjusted.
Note
When using an R, S, E, B, or W type thermocouple, a K type can be substi-
tuted. Set the ZERO-CON to 0
°
C (32
°
F).

Adjustment Device Connection Diagram
Connect the reference voltage/current generator (STV), precision digital multi-
meter (DMM), and cold junction compensator to the input terminals. In the fol-
lowing examples, the devices are connected to input 1, but connect to the
corresponding terminals when adjusting input 2.
Note
The personal computer (Configurator) is connected through DeviceNet in the
diagram above. If a CS1W-DRM21 or CJ1W-DRM21 Master Unit is being
used, the Configurator can also be connected through the Master Unit using a
peripheral bus connection. Refer to
5-1 Switching between Online and Offline
in the
DeviceNet Configurator Operation Manual
(Cat. No. W382) for details.

Compensating
conductors
Reference voltage/current generator (STV)
Remove when performing bias compensation.
Precision digital multimeter (DMM)
Use to confirm that the STV is generating an accurate voltage.
Cold junction compensator (such as a ZERO-CON)
Leave open (disabled) until performing bias compensation.
