Why does the measurement fluctuate on my Ohmic UPM-DT-50SP?
The meter is very sensitive and affected by minor air drafts or vibrations. To resolve this, place the meter on a solid surface and shield it from any air drafts.
What to do if my Ohmic Measuring Instruments meter will not zero or tare?
If your meter won't zero, it might be because the degassed water has absorbed too much air. Refill it with fresh degassed water. If the issue persists, contact Ohmic Instruments for Calibration and/or Repair.
Why does the measurement drift over time on my Ohmic UPM-DT-50SP?
The measurement may drift because the tank water has absorbed too much air. Replace the tank water with fresh, room temperature degassed water. Alternatively, bubbles may have formed on the conical target or transducer head. Wipe any bubbles from the surface of the conical target (including the bottom) and the transducer head.
What to do if my Ohmic UPM-DT-50SP display error Err 8.3?
Error 8.3 indicates an overload. Remove any excess force on the meter.
What to do if my Ohmic UPM-DT-50SP Measuring Instruments meter does not respond to the test weight or transducer power?
The Conical Target Assembly and/or the Target Support Tube might be rubbing or binding. Verify that the Conical Target Assembly and its Support Tube are correctly positioned.
How to fix Err 8.1 on Ohmic Measuring Instruments?
Error 8.1 indicates a load during power on. Remove the conical target assembly and cycle power.
What does Err 8.5 mean on Ohmic Measuring Instruments and how to fix it?
Error 8.5 indicates that the tare is out of range. Remove any excess force on the meter.
What does error Err 8.2 mean on my Ohmic UPM-DT-50SP Measuring Instruments?
Error 8.2 means the weight is below the power-on zero range. Place the meter on a level surface and cycle power.
What to do if my Ohmic Measuring Instruments display error Err 8.4?
Error 8.4 indicates an under load condition. Place the meter on a level surface and cycle power.
