    Remove Objects Too Close

    Any metal object within a 2" clearance from the probe rod, tank wall and top, riser, baffles, pipes and brackets can cause the Spill alarm to stay active.

    Clearance zone around the probe inside the tank
    1. Check the clearance around the probe — inside the riser if it's installed, and inside the tank.
    2. Either move or modify any object at least 2" from the probe. If this is not feasible, the probe will need to be relocated to a clearer part of the tank.
    3. Ensure that the TD transmitter is tightened on the probe.
    4. Enter Offset Calibration mode again (Step 1) if anything was moved, modified, or relocated.
