Raff,

What is wrong about the measurement results?

• Large difference compared to a conventional test kit? What was the value shown by the KHD and conventional kit?
• KHD results fluctuate to a large degree with each other? What were the last 3 test results?

Did you set the pump speeds correctly?
3-0-3

Is the vent tube above water?
This tube should NEVER be submersed in water.

No,no sorry maybe I'm wrong described. Liquid in waste container is let see 500 ml ,waste container of pump 3 measurment is 620ml.

If the approximate amount in the waste container is different from what is displayed in GCC or the app, then that means the waste pump should be calibrated.
