The methodof field calibration is not correct. Calibrateagain.2. The flow rate on the meter is below thelowest. Increasethe flow rate.3. The flow meter is blocked by the dry liquid.Takeout the impeller and clean it carefully and make sure the impeller turnsfreely.4. The impeller is wrapped by the sealingmaterial. Removethe meter and make sure the impeller turns freely.5. Too close to the impeller. Installproperly6. Too close to the motor or electronic noiseenvironment InstallproperlyThe reading numbers faded or blanked out.1.Batteryis exhausted or not connectedCheckthe batteries or even replace themFlow rate is normal but the meter can not count. Pressthe button of DISPLAY, the meter start.1.Field calibration is not correct.Calibrateagain.2. The impeller is blocked ordamaged. Removethe meter and make sure the impeller turns freely.3.The impeller is wrapped by the sealingmaterial. Removethe meter and make sure the impeller turns freely.Flow rate is low and the meter can not count. Pressthe button of DISPLAY, the meter start.1.The flow meter is blocked by the dry liquid. Takeout the impeller, clean it carefully and make sure the impeller turns freely.2. The flow rate on the meter is below thelowest. Increasethe flow rate.The meter can not calibrate.1.Circuit board is break down. Replacethe circuit board.2. Button is fail to press. Replacethe circuit board.Package List:1 x Turbine Flow meter
