What to do if Testomat ECO Measuring Instruments shows low water pressure?
- F
  fitzgeraldnormaAug 16, 2025
  If your Testomat Measuring Instruments indicates low water pressure, several factors could be the cause. First, check the water inlet if the LED "IN" is lit. Also, the inlet pressure may be too low due to an oxidised connector of the inlet valve. The overflow reagent might not be active, so try cleaning the filter strainer. If these steps don't resolve the issue, consider replacing the valve block, extracting the pressure regulator valve, or carrying out an adjustment.

What to do if Testomat ECO Measuring Instruments shows reagent low?
- D
  Daniel EdwardsSep 12, 2025
  If your Testomat Measuring Instruments displays a 'reagent low' message, it means the reagent quantity is below the minimum setting. Without BOB, this is 50 ml (10%), and with BOB, it's after calculation. Check the reagent level and fill it up if necessary. You can enter the level under "M” SERVICE.

What to do if Testomat ECO Measuring Instruments shows outlet to drain error?
- S
  Samantha WilliamsAug 22, 2025
  If your Testomat Measuring Instruments shows an 'outlet to drain' error, and water remains in the measuring chamber even when the LED "OUT" is lit, start by checking the water outlet. Also, the connector of the outlet valve might be oxidised. If the problem persists, consider replacing the valve block.

How to fix dosing pump cancel with horn-key on Testomat ECO Measuring Instruments?
- J
  Jamie MurrayAug 28, 2025
  If the dosing pump is canceled with the horn-key on your Testomat Measuring Instruments, it could be due to a defective dosing pump, in which case you should replace it. Another cause could be no dosing message from the dosing pump, so check the cable connection to the dosing pump.

Why does Testomat ECO Measuring Instruments show analysis cancel with horn-key?
- J
  John RiceAug 31, 2025
  If your Testomat Measuring Instruments displays an 'analysis cancel' message with the horn-key, it could be due to an incorrect analysis, such as air in the dosing capillary. Try tightening the connections of the dosing pump. Other solutions include replacing the stirring mechanism, replacing the suction insert in the bottle, or replacing the reagent, ensuring you only use HEYL Testomat® 2000 reagent.

  Veronica Torres MDSep 3, 2025
  If your Testomat Measuring Instruments shows a 'dirtiness cancel' message with the horn-key, it's likely due to dirty sight-glass windows. Clean the sight-glass windows to resolve this issue.

What causes dosing fault cancel with horn-key on Testomat Measuring Instruments?
- X
  xhowardSep 6, 2025
  A 'dosing fault cancel' message with the horn-key on your Testomat Measuring Instruments indicates a dosing inaccuracy of the dosing pump. To resolve this, replace the dosing pump or return it to the supplier for calibration.

What to do for optics cancel with horn-key on Testomat Measuring Instruments?
- K
  Katie CharlesSep 9, 2025
  If your Testomat Measuring Instruments displays an 'optics cancel' message with the horn-key, it could be due to a defective plug-in circuit board, which should be replaced. Alternatively, there might be an error with the optic component (Transmitter or Receiver defective), in which case you should replace the measuring chamber sealing rings.

Why does Testomat Measuring Instruments show turbid cancel with horn-key?
- D
  Dr. Zachary DunnSep 12, 2025
  If your Testomat Measuring Instruments displays a 'turbid cancel' message with the horn-key, it is because the water is turbid or dirty.
