MODEL CLARITY II

SECTION 8.0

TROUBLESHOOTING

This screen appears only if the analyzer was configured to convert the
turbidity reading to TSS. The first line is the slope of the calibration curve.

The second line is the lower limit for the turbidity measurement. A meas-
ured turbidity below this value will return a negative TSS value.

This screen shows the value of the analog output corresponding to the
displayed value and the scaling programmed in Section 5.3.4.

This screen shows the software version.
