The method of field calibration is not correct. Calibrate again. _x000D_ 2. The flow rate on the meter is below the lowest. Increase the flow rate. _x000D_ 3. The flow meter is blocked by the dry liquid. Take out the impeller and clean it carefully and make sure the impeller turns freely. _x000D_ 4. The impeller is wrapped by the sealing material. Remove the meter and make sure the impeller turns freely. _x000D_ 5. Too close to the impeller. Install properly _x000D_ 6. Too close to the motor or electronic noise environment Install properly _x000D_ The reading numbers faded or blanked out. 1.Battery is exhausted or not connected Check the batteries or even replace them _x000D_ Flow rate is normal but the meter can not count. Press the button of DISPLAY, the meter start. 1. Field calibration is not correct. Calibrate again. _x000D_ 2. The impeller is blocked or damaged. Remove the meter and make sure the impeller turns freely. _x000D_ 3.The impeller is wrapped by the sealing material. Remove the meter and make sure the impeller turns freely. _x000D_ Flow rate is low and the meter can not count. Press the button of DISPLAY, the meter start. 1. The flow meter is blocked by the dry liquid. Take out the impeller, clean it carefully and make sure the impeller turns freely. _x000D_ 2. The flow rate on the meter is below the lowest. Increase the flow rate. _x000D_ The meter can not calibrate. 1. Circuit board is break down. Replace the circuit board. _x000D_ 2. Button is fail to press.
