Connecting the Devices
Required for Adjustment
The following paragraphs explain how to connect the devices that must be
connected to the CRT1-TS04T for user adjustment. Wire the following devices
properly when adjusting the CRT1-TS04T.
■
Reference Voltage/Current Generator and Precision Digital Multimeter
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 0
°
C Bath) and
Compensating Conductors
Used to adjust the bias compensation value.
The cold junction compensator (the ZERO-CON 0
°
C bath is used in following
examples) is a device that maintains an accurate 0
°
C (32
°
F) temperature for
thermocouple 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).
■
CX-Integrator
Actual adjustments are made from the CX-Integrator windows.
Adjustment Device Connection Diagram
Connect the reference voltage/current generator (STV), precision digital multi-
meter (DMM), and ZERO-CON to the input terminals. Connect to the corre-
sponding input terminals when adjusting inputs 0 to 3.
Note
The personal computer (CX-Integrator) is connected through CompoNet in
the above diagram. If a CS1W-CRM21 or CJ1W-CRM21 Master Unit is being
used, the Temperature Input Unit can be adjusted by connecting the CX-Inte-
grator through the Master Unit using a peripheral bus connection.

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.
