Possible Cause
Troubleshooting Tips
No display with powered onA: Double check on the power supply
B: Instrument failure
A: Check the presence of voltage between the instrument power terminals.
B: Contact aftersales personnel.Unstable displayA: The wiring of the conductivity cell is wrong.
B: Bubbles in the pipeline.C: Unstable water quality.A Check and reconnect per the wiring diagram.
B: Rectify the pipeline or choose another measurement pointC: Change a more stable water source.Large discrepancy in readings
A: The constant is not set correctly.
B: The conductivity probe needs to be changed.C: Measurement point is not perfect.D: Wrong installation of the conductivity cellA: Reset the conductivity constant in the meter.
B: Replace the conductivity cell with a new one or recalibrate the current cell.C: Install the conductivity cell in accordance with above instructions.D: Same as C.Large deviation in measurement data
A: Meter of conductivity cell failure.B: Incorrect instrument setting.A: for conductivity cell failure, check whether the resistance between the red line and the white line of the conductivity cell is about 1 MΩ, and that between yellow line and white line is 10KΩ, and the conductivity of the battery between white line and black line insulation >100 MΩ@100V. If above conductions all correct, it means the conductivity cell is normal with no problem.B: Instrument failure, check whether the instrument’s parameter are all set correctly.Displays of the two points mA do not match.
A: Receiver migration error.
B: Not reaching 20mA.C: Improper sending setting.D: The sending of mA might be not matching.A: Reset the amount of receiving migration.
B: Loop resistance is too large, increasing the cable cross-sectional area.C: Reset the meter mA to indicate corresponding value.D: Connect the meter directly in series in the mA loop to verify the current value.
