5 Calibration

①
Calibration mode
Displays the selected calibration mode.
②
Range
In measurement and in sample replacement, the measuring range is displayed.
In the calibration gas introduction, the set calibration range is displayed.
③
Alarm/Caution
Displays the operation result of calibration coefficient.
Reference
When ALARM or CAUT. is displayed, refer to " 8 Troubleshooting " (page 75).
Note
When zero calibration alarm occurs during AIC, the span gas flows though span calibration will not be
performed for the components.
In manual calibration, the span calibration will be performed also for the alarmed components of zero
calibration.
④
Function keys
Pressing each key enables the corresponding function as follows:
ALARM
The calibration coefficient is out of the normal range.
The calibration coefficient is not revised but the previous calibration coefficient
is used for the concentration operation.
CAUT.
The calibration coefficient is within the normal range, but is close to the range
outside.
The calibration coefficient is revised to perform the concentration operation.
EXIT
Returns to the MEAS. screen 1 (Measurement value display) (page 14 Fig. 7).
RELEASE
When the calibration alarm (ALARM) or calibration caution (CAUT.) occurs, the
[RELEASE] key is displayed on the screen.
To release the alarm or caution, press this key after checking the cause of
problem. Even with ALARM or CAUT. released, the occurrence of ALARM or
CAUT. is recorded in the alarm history.
CAL.
The manual calibration is performed.
For details, refer to " 5.4 Manual Calibration " (page 28).
AIC
Starts automatic calibration.
