Calibration
Calibration Instructions
Units will be supplied calibrated for diesel.
- Install sensor in the tank and power on.
- Fill tank to required full level.
- Depress "CAL" button. Hold for 5 seconds to set full point. Release button. Check output for full point.
- Fill tank to required level or, for Min. Empty Level, remove from tank and shake to remove excess liquid.
- Disconnect power.
- Depress "CAL" button then reconnect power whilst depressing calibration button. Continue to depress for a further 5 seconds to set empty point. Release button. Check output for empty point.
