Settings and Calibration

 

 

 

Setting Description

The instantaneous measurement value that is displayed cannot be held. (Output only can be held.)

Optional modbus communications “Measurement concentration” register values are held.

If set value is selected for hold, instantaneous O2 correction value is calculated and held based on the set value.

Range identification contact output cannot be switched even if the range is switched during the hold.

Response time

The response time of the electrical system can be changed. Setting is available by components.

Note: It does not provide exact seconds for the setting time, rather, it provides a guide of the setting time.

The setting value can be modified as requested by the customer.

Average Period

This screen allows you to set an averaging period for the average values of O2 correction and O2 average.

It enables you to set an average time of 1 to 59 minutes (1-minute step) or 1 to 4 hours (1-hour step).

Changing the setting also resets the averaging of O2 correction and O2 average value. (Pressing the ENT key resets averaging only for the components whose setting were changed.)
