Temperature Input Unit Functions
Section 11-6
Stabilization Times
required in Each Step The following diagram shows the stabilization times (waiting times) required
when adjusting all 4 inputs.
Note (1) The terminal block temperature stabilization time does not affect the up-
per/lower limit adjustment after changing the wiring for input 1, so the ad-
justment can be performed immediately if 30 minutes have passed since
the Temperature Input Unit's power was turned ON.
(2) To perform the adjustment procedure properly, always allow sufficient
time for the temperature to stabilize. Also allow sufficient time for devices
such as the STV, DMM, and ZERO-CON to stabilize. Refer to each de-
vice's operating manual for details.
