What to do if the display is blinking on my horiba HR-200RT?
- S
  Scott MoyerAug 16, 2025
  If your Horiba Measuring Instruments display is blinking and the value is outside the measurement range, it could be due to a high concentration. Verify that the concentration is within the measurement range by performing manual analysis. If the concentration is within the measurement range, contact HORIBA Advanced Techno. Another cause could be a temperature sensor error. In this case, perform a temperature calibration.

Why is there fluctuation in the measured value of my horiba HR-200RT Measuring Instruments?
- E
  Elizabeth OrrAug 22, 2025
  If you're experiencing fluctuation in the measured value of your Horiba Measuring Instruments, there are several potential causes. Air bubbles may be forming in the sample, so prevent their formation. A sudden change in the liquid temperature can also cause this issue, so install the instrument in a location with stable temperature. Ensure that the pH fluctuation is moderate. The electrical conductivity should be 8 mS/m or above. Adjust the flow rate to be within the specification range. Set a higher value for dF if the moving average count is low. Supply the specified amount of beads if an excessive amount is supplied. Also, check and tighten the terminal block screw securely and remove any humidity or contamination from the terminal block.

How to troubleshoot a horiba HR-200RT Measuring Instruments that does not turn ON?
- J
  Jeremy HarveyAug 26, 2025
  If your Horiba Measuring Instruments does not turn on, the power supply voltage may be outside the rated voltage range, so check the power supply voltage. Also, check the power distribution line for any wiring errors. If these steps don't resolve the issue, there may be an internal error of the converter, in which case you should contact HORIBA Advanced Techno.

What to do if my horiba HR-200RT indicates an abnormal value?
- C
  cwatsonSep 12, 2025
  If your Horiba Measuring Instruments shows an abnormal value, several factors could be at play. Start by checking for electrode contamination and clean the electrode, polishing it with the provided abrasive paper. Next, inspect the connector cable for any disconnections or short circuits. Also, check the terminal block for contact failure. Ensure the sample flow rate is within the specified range, and verify that the wiring is correctly connected to the terminal block.
