    Why does the measurement fluctuate on my Ohmic instruments UPM-DT-10PA?
    • J
      James WolfeAug 15, 2025
      The fluctuation of measurement in Ohmic instruments Measuring Instruments is caused by an unstable environment. The meter is very sensitive and is affected by minor air drafts and/or vibrations. To resolve this, place the meter on a solid surface and shield it from any air drafts.

    Why does the measurement drift over time on Ohmic instruments UPM-DT-10PA Measuring Instruments?
    • B
      Blake WhiteAug 21, 2025
      The measurement drift in Ohmic instruments Measuring Instruments could be due to several reasons: * The tank water has absorbed too much air. Replace the tank water with fresh, room temperature degassed water. * The conical target has developed bubbles on its surface. Wipe any bubbles from the surface of the conical target, including the bottom. * The transducer head has developed bubbles on its surface. Wipe any bubbles from the surface of the transducer head.
