Perform manual chemical purge
  • Always before relative humidity calibration and adjustment
  • If you think the sensor has been exposed to an interfering chemical.
You can activate manual chemical purge by turning the startup purge on temporarily and resetting the probe. After the operation, to turn off the startup purge, use the PUR command.
Before starting calibration, make sure that the sensor temperature has reached normal temperature.
