What to do if Milltronics Control Unit reading is fixed?
If the reading is fixed, regardless of the actual material level, the transducer beam may be obstructed, the standpipe is too narrow, or the transducer mounting is resonant. Relocate and / or reaim transducer at material level or object.
What to do if my Milltronics Control Unit always reports the material level 'off'?
If the material level reported is always 'off' by the same amount, the empty (zero) reference is incorrect. You should check Empty (P006), Reading Offset (P063), Offset Calibration (P650), & Offset Correction (P652).
What to do if Milltronics Control Unit displays 'EEEE'?
If the Milltronics Control Unit displays 'EEEE', it means the reading is too high. To resolve this, select larger units (P005) or lower the Convert Reading value (P061).
What to do if Milltronics Control Unit reading is erratic?
If the reading is erratic with little or no relation to the material level, the true echo may be too weak or the wrong echo is being processed. Try to relocate and / or reaim transducer at material level or object.
