The KH Test reagent pump speed is set at the factory and generally does not need modifying. There is an option to calibrate this pump head in the app but in most cases this is not advised and if done wrongly can cause testing issues.

Depending on the age of the KH Manager and the reagent tubing version you have installed the KH Test reagent pump will rotate at a speed of approximately 4-5 second if set for the thin reagent tube or approximately 9-10 seconds for the thicker reagent tube.

If the test duration of the KH Manager is above 60 minutes or below 10 minutes then it could be that the pump speed is set incorrectly for your machine and will need re-setting. To do this go in to the 'Settings' section for the KH Manager in the Kamoer Remote App. In here enter 'Maintain' then 'Calibration' and an option to 'Reset Calibration' is shown at the bottom of the list, select this and then choose 'Reset Speed of KH Test Pump', three versions will be shown with corresponding images. Choose the option that matches your unit and save by selecting 'OK' at the bottom of the screen.

When done return to the 'Test' page in the app and run a KH/pH test to confirm the setting has been successful. The normal test duration is approximately 35 - 40 minutes.
