Average period
It allows you to set an average period of the
average value of O
2 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
O
2 correction and O 2 average value. (Pressing
the ENT validates the resetting only for compo-
nents whose setting was changed.)
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.
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 that the average value
will not be correct for 1 hour after resetting.
