3.6 External Oxygen Meter Settings
This section describes necessary and restrictive settings when using the ZR802G as an oxygen
analyzer.
(For details on setting items, see the ZR802G user’s manual, IM 11M12G01-02EN).
For the use of other external oxygen analyzers, also refer to this section for settings.
l
Equipment settings - mA output settings
Set the current output “20 mA point” used as an output to IR800G/IR810G to 100% O
2
.
n
Setting for automatic calibration at the same time as the schedule set
by IR800G or IR810G.
l
Maintenance - Calibration Settings
● Calibration mode
Set to “semi-automatic.”
● Stability time
Set to 0 minutes and 0 seconds. If there is insufficient time for the oxygen concentration to
stabilize after calibration, tune the replacement time of the IR800G/IR810G. (See 5.1.2 Auto
Calibration Setting for more information on replacement time)
There are no restrictions on the calibration procedure, zero gas concentration, span gas
concentration, or calibration time [mm:ss]. Set appropriate values.
l
Setting - Contact setting - Contact output setting
To notify IR800G/IR810G of the end of calibration or errors during calibration, the following
settings are required for one of the contact outputs 1 to 3.
● For contact output operation
Set to “closed.”
● For contact output
Assign the contact output to “Calibrating” to notify the end of calibration.
IR800G/IR810G. The assigned contact output should be connected to the contact to which “O
2
meter input” is assigned in the IR800G/IR810G contact input setting.
Assign “Calibration factor alarm” and “Calibration stability alarm” to one contact for notification of
errors during calibration. Connect the assigned contact output to the contact to which “O
2
meter
error” is assigned at the IR800G/IR810G contact input. (For error notification during calibration,
calibration will operate even if no assignment is made to a contact.)
l
Setting - Contact setting - Contact input setting
The following settings are required to receive semi-automatic calibration initiation from IR800G/
IR810G.
● Operation selection for contact input X (X is 1 or 2)
Set to “Operate on Close”.
● Selection of contact input X (X is 1 or 2)
Set to “Calibration start command.
