Question
How do the TSS portable errors "calibration insufficient +" and "overflow area" differ in how they are generated?
Summary
TSS portable "calibration insufficient +" and "overflow area" errors
Answer
Error "overflow area" designates that a probe is measuring in an unsuitable medium - It may be necessary to recalibrate. This error occurs when the sludge concentration is at the upper end of the measurement range and almost no light is reflected back to the sensors detector. Setting up a new calibration curve is recommended. If the problem continues, the sludge concentration is too high to be measured with the TSS portable probe; the value is beyond the probes measurement range.
