FAQ

  • Q The instrument displays garbled characters or flickers. What should I do?

    ① Power cycle the device;
    ② Check if the voltage is stable or out of range;
    ③ Eliminate strong electromagnetic interference; ensure proper shielding and grounding.

  • Q The radar level transmitter displays full scale or remains at zero. What should I do?

    ① The antenna is fouled or obstructed; clean the antenna;
    ② Incorrect parameter settings (range, dead zone); reconfigure settings;
    ③ Improper installation location (near the feed inlet or tank wall); adjust the position.

  • Q How should I handle abnormal displays or no output from a pressure transmitter?

    ① Check the power supply and wiring;
    ② Confirm that the range and unit settings are correct;
    ③ Calibrate the zero point;
    ④ Check if the sensor is overloaded or damaged.
