Chapter 9 Failure Analysis and Removal

Question 1: No display on the controller?
Answer: Make sure that the power supply wiring is correct and the power supply
can supply power normally.
Question 2: The controller display numbers jump up and down?
A: Check whether there are any interference devices such as inverters around, and
pay attention to stay away from these interference devices or take shielding
measures.
Q3: The controller cannot be calibrated?
Answer: The standard solution is not prepared correctly or the electrode is
damaged.
Question 4: The display area of the screen is that the sensor is not connected?
A: Confirm whether the sensor is disconnected.
Q5: Wrong sensor selection?
A: You can press and hold to re-enter

the sensor selection interface and

select the correct sensor.
