    Why does my Kurz 454FTB Measuring Instruments display 'RP resistance above high limit'?
    • S
      Stephanie GrayAug 19, 2025
      A reading of 'RP resistance above high limit' on your Kurz Measuring Instruments indicates a potential open circuit on the sensor wiring or a defective sensor or sensor control board.
  • E

    Why does my Kurz 454FTB display 'RP resistance below low limit'?
    • C
      collinsjeffreyAug 21, 2025
      A reading of 'RP resistance below low limit' on your Kurz Measuring Instruments indicates a short in the sensor wiring or a defective sensor or sensor control board.

    What causes 'RTC resistance above high limit' in Kurz 454FTB?
    • M
      melanie87Aug 23, 2025
      If your Kurz Measuring Instruments display 'RTC resistance above high limit', this could be caused by an open circuit on the sensor wiring or a defective sensor or sensor control board. When the meter reaches the limit, the meter turns off the sensor control drive until it cools.

    What does it mean when my Kurz 454FTB Measuring Instruments say 'Sensor RPs lead open circuit'?
    • N
      Nicholas StevensAug 28, 2025
      If your Kurz Measuring Instruments are showing 'Sensor RPs lead open circuit', it means there is an open circuit on the RPs wire, or there is a defective sensor or sensor control board.

    Why does my Kurz 454FTB show 'Wire loop resistance above high limit'?
    • S
      stephanieavilaAug 30, 2025
      A 'Wire loop resistance above high limit' message on your Kurz Measuring Instruments indicates that the wire is too long for the gauge being used, there is a loose wire joint connection, or a defective sensor or sensor control board.
  • C

    What does it mean if my Kurz 454FTB display 'Meter kick-out high'?
    • M
      Martin LoveSep 1, 2025
      The 'Meter kick-out high' alarm on your Kurz Measuring Instruments is normal if the flow rate or temperature is above the user programmable kick-out set point.
  • D

    What does it mean if my Kurz 454FTB Measuring Instruments display 'Meter kick-out low'?
    • S
      swansonpatrickSep 4, 2025
      The 'Meter kick-out low' alarm on your Kurz Measuring Instruments is normal if the flow rate or temperature is below the kick-out set point, which is user programmable.
  • B
    Bradley CollinsSep 6, 2025
    What causes 'Sensor type does not match configuration' error in Kurz 454FTB Measuring Instruments?
    • K
      Kelly LarsonSep 6, 2025
      A 'Sensor type does not match configuration' error in Kurz Measuring Instruments indicates that the wrong sensor is connected to the electronics, or there is a defective sensor or sensor control board.
  • A
