Use the following procedure to confirm operation of the system.
(1) Configure the settings of this device and the system controller while referring to "8. Initial Settings".
(2) Confirm whether the measurement values of channel 1 and channel 2 are displayed on the system controller properly.
* Depending on the conditions, compare the measurement values with those of, for example, a commercially available portable
thermohygrometer.
If the measurement accuracy of the sensor used results in extreme differences in the measurement values, use the
measurement correction value (offset value) input function of the system controller to correct the measurement values.
(3) When upper/lower limit alarm interlock is to be used, input a value that exceeds the set alarm level and confirm whether the alarm
is displayed on the controller. Furthermore, confirm whether the alarm output operation takes place from the contact output at the
same time.
If there is a problem, check the wiring and settings.
For details on configuring settings, refer to "8. Initial Settings" and "9. Dip switch functions".
