Why is the material level reported by Milltronics Measuring Instruments always off?
If the material level reported by your Milltronics Measuring Instruments is consistently off by the same amount, it's likely due to an incorrect Empty (zero) reference. Check Empty (P006), Reading Offset (P063), Offset Calibration (P650), and Offset Correction (P652).
What to do if my Milltronics Measuring Instruments display 'LOE'?
If your Milltronics Measuring Instruments display is showing 'LOE', it indicates a weak or non-existent echo. To resolve this, try relocating and/or re-aiming the transducer at the material level or object.
Why is my Milltronics Control Unit display blank?
If the display is blank and the transmit neon isn't flashing, and the transducer isn't pulsing, it's likely due to a power issue. Check the power supply, wiring, and voltage selection switch to ensure everything is correctly configured and functioning.
What does 'Short' and 'tb:(#)' mean on my Milltronics Control Unit?
If the Milltronics Control Unit displays 'Short' and 'tb:(#)', it indicates a short circuited transducer cable or a defective transducer. Repair or replace as necessary.
What does 'Error' and 'tb:(#)' mean on my Milltronics Control Unit?
If the Milltronics Control Unit displays 'Error' and 'tb:(#)', it means the wrong transducer is selected (P004). Enter the correct value.
What does 'Open' and 'tb:(#)' mean on my Milltronics Control Unit?
If the Milltronics Control Unit displays 'Open' and 'tb:(#)', it indicates an open circuited transducer cable, or a defective transducer. Repair or replace as necessary.
What causes 'No response to programmer' in Milltronics Control Unit?
If there is no response to the programmer, it could be due to an obstructed infrared interface or a defective programmer. Clean the enclosure "docking bay" and programmer magnet slot.
What to do if Milltronics Control Unit reading fluctuates?
If the reading fluctuates while the material level is still (or vice versa), the measurement stabilization is incorrect. Alter the Measurement Response (P003) accordingly.
What to do if Milltronics Control Unit displays 'LOE'?
If the Milltronics Control Unit displays 'LOE', it indicates a weak or non-existent echo. Try to relocate and / or reaim the transducer at the material level or object.
Why does Milltronics Control Unit measurement accuracy improve as level nears transducer?
If measurement accuracy improves as the level nears the transducer, it indicates that the incorrect sound velocity is being used for distance calculation. Use an ultrasonic / temperature transducer or a TS-3 temperature sensor.
