Test equipment that is not calibrated can give false results — which is dangerous in gas appliance testing. Here is a practical maintenance checklist:
1. Regular Calibration
Calibrate pressure, temperature and flow sensors at least once a year, or according to your quality system (ISO 9001).
2. Daily Checks
Check gas tightness, electrical connections and safety devices before each production shift.
3. Preventive Maintenance
Replace filters, clean sensors and verify control loops on a scheduled basis to avoid unplanned downtime.
4. Keep Records
Maintain calibration certificates and maintenance logs — they are required for audit traceability.
