Trouble Removal of sensor and instrument
| Problem | Possible causes | Trouble shooting |
| No display when powered on | A．Bad connection of power supply B．Instrument fault | A．check to see if there is 24Vvoltage between power terminals 24VA and 24VB. B．Check by professional technicians. |
| Unstable display | A．Improper wire connection of sensor B．Air bubbles in the pipeline C．Unstable water quality D．Badness connection port | A．Refer to the instruction manuals B．Select the proper measurement point or change the pipeline C．Stabilizing the water quality D．Check the connector to be connected |
| Big deviation | A．Sensor fault B．The cable is damaged C．Lncorrect installation D．Setting problem | A．Take out the sensor from the pipeline and calibrate B．Replace the sensor which can not be calibrated C．Find the correct measurement point and use the flow device D． Reset the parameter of the instrument |
| The transformer is inconsistent with the display | A．Loop resistance is too large B．Incorrect connection mode C.Unusual power supply D.Wrong transfervolume | A．Replace the cable to reduce the loop resistance B．Check the connection right or notpowered by the standard C．Reset the transferred volume |
