Verification
1. After calibration is complete and the detector returns to normal
operation, verify the calibration using a gas cylinder other than
the one used for calibration.
2. The gas concentration should not exceed the sensor's detection
range. Confirm the LCD shows the expected concentration.
3. To ensure the readings are accurate, apply the verification gas
for the same amount of time as was applied to the sensor when it
was calibrated.
Example: H

S span time 2 minutes therefore, apply verification
gas for 2 minutes.
