Resetting User Adjustments
If it is necessary to reset the upper limit adjustment value, lower limit adjust-
ment value, and bias compensation value to the factory defaults, click the
Default Setting
Button. The settings will be returned to the factory settings.
The upper/lower limit adjustment values and bias compensation value are all
initialized at the same time.
Note
1. The bias compensation value may not be accepted if there is a large tem-
perature difference between the Terminal Block and ZERO-CON (0
°
C
bath). If this problem occurs, correct the adjustment system by using a ZE-
RO-CON compatible with the sensor being adjusted or other means.
2. Always test the indication accuracy after making user adjustments to verify
that the adjustments are correct. Test the indication accuracy at three
points: the lower limit value, an intermediate value, and the upper limit val-
ue.
• Connect the external devices as shown in the following diagram.
• After verifying that the ZERO-CON is set to 0
°
C, set the STV’s output
voltage to produce a voltage equivalent to the test voltage.
Note
Always use the compensating conductors (the same kind that will be
used with the sensor being adjusted) to connect the ZERO-CON to
the GRT1-TS2T’s input terminals.
Note
In order to perform the adjustment procedure properly, always allow sufficient
time for temperature stabilization, as shown in the following diagram. Also
allow sufficient time for devices such as the STV, DMM, and ZERO-CON to
stabilize. Refer to each device’s operating manual for details.
Stabilization Times Required in Each Step
The following diagram shows the stabilization times (waiting times) required
when adjusting both inputs.
