Troubleshooting
If the ST-730 series probe output signal is not stable and fluctuates significantly, make an additional ground
connection – connect the clear (shield, earth ground) wire to a conductor that contacts the sample water
electrically such as a brass pipe adjacent to the ST-730 series tee.
Carry out routine calibration verification against a qualified turbidity standard. After properly cleaning the
ST-730 series sensor, carry out the zero point and slope calibration using the qualified turbidity standard.
