Common Faults and Troubleshooting Measures | 47
25
Failure of liquid sensor
calibration (E17)
1.Visually check whether the buffer ring detected by the liquid sensor is
discolored and contaminated. If it is contaminated, at first, use the deep
cleaning function to clean the buffer ring. If it still fails, it needs to be
removed for manual cleaning;
2.Check whether the cable of the liquid sensor is loose and has a poor
contact;
3.Operate the liquid sensor with the system diagnostic function of the
instrument, and check whether the voltage of the liquid sensor is
correct when the buffer ring is in the state of empty tube (filled with air)
or full tube (filled with deionized water);
4.Cut off the power supply of the instrument, power on it again, and
calibrate the liquid sensor. If the fault still occurs, contact the after-sales
personnel to confirm the fault and repair it.
26
Calibration curve expires (W19)
1.Confirm that curve calibration has been done under the current
measuring range and the calibration is successful;
2.Enter Parameter Setting-Calibration Parameters-Current Parameters,
view the current curve information, and check whether the current
curve and factory curve information are existing;
3.When the current calibration curve exceeds the time limit by one month,
the curve needs to be re-calibrated.
27
Failure of LED calibration (The
high value exceeds the limit
value (E29)
1.Check whether the calibration setting concentration is consistent with
the current calibration concentration; if they are inconsistent, conduct
the modification and calibration;
2.Shut down the instrument, remove the LED and PD, and observe
whether there are impurities or dirt on the light path. If there is dirt, use
cotton swabs dipped in alcohol to clean it;
3.Turn on the instrument and use the maintenance function of the
instrument to deeply clean the M-cell;
4.After all the above steps have been checked and the problem is solved,
recalibrate LED; if the fault still occurs, please contact the after-sales
personnel to confirm the fault and repair it.
28
Failure of LED calibration (The
high or low value exceeds the
limit value by 20%)
1.Shut down the instrument, remove the LED and PD, and observe
whether there are impurities or dirt on the light path. If there is dirt, use
cotton swabs dipped in alcohol to clean it;
2.Turn on the instrument and use the maintenance function of the
instrument to deeply clean the M-cell;
3.After all the above steps have been checked and the problem is solved,
recalibrate LED; if the fault still occurs, please contact the after-sales
personnel to confirm the fault and repair it.
