    What to do if GESTRA Measuring Instruments equipment fails to work?
    • J
      James WalkerAug 10, 2025
      If your GESTRA Measuring Instruments equipment isn't working, start by checking the power supply and all electrical connections to rule out a power failure. If the issue persists, the electronic circuit board might be faulty, so you should check or replace it. Also, ensure the earth connection to the vessel isn't interrupted; clean the seating surfaces and screw in the conductivity transmitter with a new sealing ring, avoiding insulation of the electrode thread.

    Why is GESTRA Measuring Instruments equipment not working accurately?
    • R
      Ricardo StephensonAug 17, 2025
      Inaccurate readings from GESTRA Measuring Instruments can stem from several causes. Start by checking for dirt on the transmitter measuring electrode(s) and clean them if necessary. For LRGT 16-2 models, ensure the spacer disc PEEK 8 is correctly positioned. Also, if the conductivity reading is higher than expected, reduce the temperature coefficient during commissioning or the cell constant during operation. Conversely, if the reading is lower, increase these values. If adjusting the cell constant doesn't resolve the issue, remove the conductivity transmitter and clean the measuring surface or electrodes.

      Laura JonesSep 1, 2025
      To avoid electric shock when working on GESTRA Controller electrical systems: * Always switch off the voltage to the equipment before working on the terminal strips (installation, electrical connection, disassembly). * Disconnect all poles of the supply cable from the mains and secure them so they cannot be switched back on. * Before starting work, check that the system is not carrying live voltage.

    What to do if LEDs indicate a malfunction in GESTRA Measuring Instruments?
    • A
      Anthony StewartNov 23, 2025
      If the LEDs on your GESTRA Measuring Instruments are indicating a malfunction, consider these potential issues: * Check the electrode wires for interruptions or exposed measuring surfaces/electrodes, ensuring connections are secure at the electronic circuit board (terminal lugs 1-4). Also, check the water level and installation. * Inspect the electrode wires for short circuits, again checking connections at the electronic circuit board (terminal lugs 1-4). * If the value is below the set value of 0%, check the water level and installation. * If the value is above the set value of 100%, set a larger measuring range. * If the temperature in the terminal box exceeds 85°C, ensure the ambient temperature does not exceed 70°C. * For open or short circuits in wires to the resistanc...
