    How to check for ground loops in GLI International C53 Measuring Instruments?
    • V
      Vanessa GutierrezAug 3, 2025
      To determine if ground loops exist in GLI International Measuring Instruments, perform this test: 1. Display the conductivity MEASURE screen and put the sensor in a non-conductive container (plastic or glass) filled with a known value conductivity reference solution. Note the analyzer reading. 2. Connect one end of a wire to a known earth ground, such as the analyzer grounding strip or a metal water pipe. Place the other end of this wire into the reference solution next to the sensor. 3. Compare the new analyzer reading with the reading from step 1. A change indicates a ground loop.

    What are the symptoms of ground loop in GLI International C53 Measuring Instruments?
    • M
      Mary TaylorAug 9, 2025
      If your GLI International Measuring Instruments are showing ground loop symptoms, you might observe that the analyzer reading is consistently offset from the actual value, frozen on one value, or is reading off-scale (either upscale or downscale).

    How to verify analyzer operation in GLI International C53?
    • E
      edward46Aug 25, 2025
      To verify analyzer operation for GLI International Measuring Instruments: * Reconnect line power to the analyzer. Check if the analyzer conductivity reading is full-scale for the applicable range and that the analyzer temperature reading is 0°C. * After disconnecting line power and the sensor(s), connect a 1% tolerance, 1097 ohm resistor between Terminals 18 (blue) and 19 (white) on TB1.
