Chapter 8 Troubleshooting
No display on controller?
A: Check if the power cable is correctly connected, power is on.
Number in display is jumping up and down?
A: Check if there is any interference equipment such as frequency
converter is nearby. The instrument should be kept away from such
interference equipment or protected with good shielding measures.
Conductivity instrument can not be calibrated?
A: The standard solution is not mixed in a correct way or the electrode is
damaged.
The instrument can not measure accurately after calibration with a standard
solution of conductivity of 1413us/cm?
A: Check if the standard solution is polluted. Replace the solution and
calibrate again.
The response of number is slow?
A: If the electrode is covered by dirt, the response would be slow. Clean the
pollutant in a corresponding method. A slow response is normal in winter.
