Page 25: Maintenance
Periodically, sensors should be exposed to refrigerant sample and the results logged. For proper operation it is essential that the test and calibration schedule be adhered to. Honeywell Analytics recommends the following maintenance schedule: • Calibration should be performed with certified calibration gas every six months. -
