Maintenance
Refrigerant leak detector R454B calibration
Calibration of this component must be done every year. It is important to ensure proper accuracy and operation of
the detector.
There are two different methods to fulll the calibration requirements:
Replacing the sensor head with a new factory pre-calibrated sensor It is necessary to make an order of this sensor
head as spare part.
After sensor head exchange, the detector must be tested with the on-board test button function, which simulates
alarm signals and relay activation, to ensure all electrical components are functional.
This method is preferred due to the following factors:
- As sensors have a limited lifetime, this method basically ensures that the customer has a gas detector as good as
new after replacing the sensor head.
- The method is typically more efcient and cost effective compared to calibration carried out on site.
Performing a calibration to the sensor using calibration gas (gas mixture with known target gas concentration)
Test equipment and basic competence in Calibration is required to carry out this method.
Calibration equipment for Gas Detection Units (GDU) consists of:
• Valve/Flow regulator.
• Gas cylinder with the correct calibration gas for each refrigerant and concentration (ppm).
• Calibration adapter.
In order to execute the calibration function, the gas detector unit needs to be equipped with a display or connection
to either the service tool or the PC tool.
