    What to do if Ametek Drexelbrook ThePoint Measuring Instruments readings are too low?
    • C
      corey99Aug 2, 2025
      If the readings on your Ametek Drexelbrook Measuring Instruments are lower than expected, you should first check if the tank is full or if there's a significant coating present on the sensor. Additionally, cleaning the sensor and re-measuring the sensor resistances might resolve the issue.

    What to do if Ametek Drexelbrook ThePoint unit appears dead?
    • D
      Danielle GuerreroAug 7, 2025
      If your Ametek Drexelbrook Measuring Instruments unit appears dead, try removing and then reapplying power. If that doesn't work, press the reset button. Observe the two LEDs flashing for about 60 seconds, after which the green LED should light up. Then, touch the sensing element with your finger; if the circuit board is working, reinstall the instrument and press reset.

    Why Ametek Drexelbrook ThePoint reading is zero?
    • R
      Randall Baird MDAug 12, 2025
      A zero Ohms reading on your Ametek Drexelbrook Measuring Instruments typically indicates a metal-to-metal short circuit. Check for any contact between the sensor and the tank wall, mounting nozzle, or any other tank structure.

    What to do if ThePoint is stuck on Ametek Drexelbrook ThePoint Measuring Instruments?
    • G
      georgebentleyAug 17, 2025
      If ThePoint on your Ametek Drexelbrook Measuring Instruments is stuck in one state, begin by removing power and then disconnecting the coax cable that connects the sensing element to the electronic unit. After this, reapply power. If ThePoint changes state with the sensing element disconnected, the sensing element is likely faulty.

    Why does ThePoint change state when moving jumper on Ametek Drexelbrook Measuring Instruments?
    • S
      Steven KirbyAug 23, 2025
      If ThePoint changes state while moving the jumper, but not when touching the sensing element on your Ametek Drexelbrook Measuring Instruments, the integral cable is likely faulty.

    What to do if ThePoint fails all tests on Ametek Drexelbrook ThePoint?
    • C
      Charles WilliamsAug 27, 2025
      If ThePoint fails all the tests on your Ametek Drexelbrook Measuring Instruments, the instrument is likely faulty. Use a replacement electronic unit to determine the exact fault.
