Average period
It allows you to set an average period of the average value of
O2 correction.
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 resets the average value of O2
correction and O2 average value. (Pressing the ENT
validates the resetting only for components whose setting
was changed.)
Example of average action
Suppose the average period is 1 hour.
• Sampling occurs every 30 seconds
• Every 30 seconds, the average for last 1 hour (time setting) is output.
• At the instant of resetting, zero is assumed for all past values. It means the average value will not be
correct for 1 hour after resetting.
Maintenance mode
To open the maintenance mode, enter a password. After entering the password, press the ENT key.
The password can be used for the Password Setting in the Maintenance mode. A password is set to
“0000” before factory-shipment. This value is available for the Maintenance mode.
