CALIBRATION MODE Operation
Due to the nature of the Gas detector, stabilization time of at least 30 minutes is required after power
supply; management criteria may vary depending on the field condition.
10.4.1.
Zero Calibration
Touching "FUNC" switch with Magnet-bar for 2 seconds in Measuring
Condition will enter the Password mode.
Touch the "FUNC" switch after setting password using "↑" or "↓" switch.
Select “CALIBRA. MODE” by touching "↑" or "↓" switch.
Touching “FUNC” switch when “CALIBRA. MODE” is displayed will enter
Calibration Mode.
Measuring Condition will return on touching “RESET” switch.
Touching “FUNC” switch when “CALIBRA. MODE” is displayed will select
Calibration Mode.
Select [ZERO] by touching "↑" or "↓" switch. Now, touch “FUNC” switch to
enter Zero Calibration mode.
Select [YES] by touching "↑" or "↓" switch. Now, touch “FUNC” switch to
carry out Zero Calibration.
Inject clean air or 100% nitrogen gas into the sensor using a calibration
device at 1000mL/min for a minute; touch “FUNC" Switch when Measuring
Value was stabilized to carry out Zero calibration automatically.
After a successful Zero calibration, "ZERO SUCCESS" will be displayed on LCD
Display for 2 seconds, and the mode will switch to "CALIBRATION DATA"
Mode.
When Zero Calibration does not succeed, "ZERO FAIL" is displayed for two
seconds, and it will switch to "CALIBRATION DATA" Mode.
ZERO FAIL happens when sensor input exceeds 70% of ADC input range.
It’s the Mode displaying Measuring Value after Calibration and the function
to check if the calibration was performed normally.
If Failed, FAIL Text and current Measuring Value will be displayed at
1-second intervals.
"CALIBRATION MODE" returns on touching “RESET" Switch.
