Calibration Instructions
Units will be supplied calibrated for diesel. They can be recalibrated for alternative fuels:
Full Point:
- Install sensor in the tank or flask and power on.
- Fill tank to required full level with required fuel.
- Remove calibration bung from sensor and use a suitable tool to depress PCB mounted calibration button. Hold for 5 seconds to set full point. Release button.
- Check full point and refit bung.
Empty Point (if required):
- Fill tank to required level or, for Min. Empty Level, remove from tank and shake to remove excess liquid.
- Disconnect power.
- Remove calibration bung from sensor and use a suitable tool to depress PCB mounted calibration button then reconnect power whilst depressing calibration button. Continue to depress for a further 5 seconds to set empty point. Release button.
- Check empty point and refit bung.
*These sensors cannot be installed inverted.
