According to the Danfoss DGS Functional Tests and Calibration Procedure User Guide, the sensor is calibrated at the factory and a calibration certificate is provided. However, after installation, the zero calibration and recalibration (gain calibration) should be executed only if the sensor has been operating longer than the calibration interval or has been in stock longer than the storage time specified in the table provided in the user guide.
The calibration intervals and storage times for different spare sensors are as follows:
- Spare sensor DGS-IR CO2: Calibration interval of 60 months and storage time of approximately 6 months.
- Spare sensor DGS-SC: Calibration interval of 12 months and storage time of approximately 12 months.
- Spare sensor DGS-PE Propane: Calibration interval of 6 months and storage time of approximately 6 months.
It is important to note that the frequency and nature of testing or calibration may be determined by local regulations or standards. To comply with the requirements of EN378 and the European F-GAS regulation, sensors must be tested at least annually. However, it is recommended to check local regulations on calibration or testing requirements.
Failure to test or calibrate the unit in accordance with the instructions and industry guidelines may result in serious injury or damage. Therefore, it is crucial to follow the guidelines provided in the user guide and perform testing and calibration as necessary to ensure correct functionality of the sensor.
