SENSOR SPAN
This step is performed when an accurate laboratory value has been obtained from the sample
previously taken during the SNAPSHOT procedure. Select the "SENSOR SPAN" option from the
SENSOR SETUP menu using the up and down arrow buttons and press the "ENTER" button. The value
that was previously saved snapshot will be displayed. Use the up and down arrow buttons to adjust the
analyzer reading to the value of the laboratory analysis. Press the "ENTER" button when done. The
system is now calibrated and ready for normal operation. Press the "MENU" button to exit or use the up
and down arrow buttons to select another sensor setup option.
DEFAULT SPAN
This calibration mode will replace the current span calibration value with the factory default value.
This may be useful when using the system in a new application. If the analyzer has been properly
zeroed in clean water, the analyzer will read values that are typical for an average waste treatment plant.
No absolute accuracy is guaranteed after this procedure, but the numbers will, in the least, be useful for
observing trends in the suspended solids concentration over time.
RESPONSE TIME
The response time parameter will allow the adjustment of the amount of averaging taking place.
This is entered in the amount of time it will take to achieve a stabilized reading, in seconds. This may be
useful when using the system in a new application or trouble shooting.
SENSOR CURVE
The sensor curve mode will allow the selection of a standard TSS sensor curve which should be
used for most applications or a special TSS sensor curve which can be used for applications when the
standard curve does not apply. Contact the factory for details on using the special curve setting.
PASSCODE
The passcode parameter will allow the operator to limit access to the sensor setup parameters. The
passcode may be set to any three-digit number.
