4.6 Calibration
There are two calibration techniques; depending on whether turbidity or suspended solid
is required (refer to
the behavior of the 4–20 outputs and alarm relays while the user is in the Calibration menu
(refer to

Display depends on the selection in configuration.
Return the instrument to the default calibration settings.
Enter up to a 10-digit name in any combination of symbols and alpha or numeric characters.
This setting configures the Solitax to measure turbidity or suspended solids. The Solitax cannot
simultaneously measure both. Choose "TRB" for turbidity measurements, or "TS" for suspended
solids measurement. This selection determines which units may be selected in the "Meas Units"
menu.
Choose from the displayed units. TRB (FNU, EBC, TE/F, NTU); TS (mg/L, g/L, ppm, %)
Default: FNU
If TRB was selected in set parameter, select "NTU" (commonly used in the U.S.), FNU, EBC, or
TE/F. If TS was selected, choose mg/L, g/L, ppm, or %. Press enter to choose the selection. If
the units selected result in a reading that exceeds 4 digits, the display will only show dashes.
For example, if mg/L were selected, and the measurement was 10,500 mg/L, the display will
show dashes until the reading drops to 9999 or lower.
Select the cleaning interval (1, 5, 15 or 30 minutes; 1, 4, or 12 hours; 1, 3, 7 days)
Default: 12 hours
This is the interval between wiper cleaning of the sensor window. It is recommended to start with
a setting of 30 minutes. This time may be adjusted according to the application. If readings
continue to be accurate, try a longer interval. If not, shorten the interval.
This is a damping function. While the Solitax takes readings continually, it will average them
together over the period of the response time. Once the response time has elapsed, the
displayed reading, 4-20 outputs, and alarm status are updated. (0 to 300 seconds)
Default: 3 seconds
This is the datalog interval, with options from 1–15 minutes. Values logged are the average of
the all readings during the previous logging interval. The controller will hold approximately
360 days of readings for one sensor at 15 minute intervals, or 24 days at 1 minute intervals (and
proportional in between). Default:10 minutes
Resets all user-editable options to the factory-defaults.
Displays the sensor type, entered name of the sensor (Default: sensor serial number), the sensor
serial number, the software version number, and the sensor driver version number.
Select Profile Counter to display the number of wipes made (from 20000 backwards). Select
Reset Config to manually reset the profile counter.
Shows the number of hours or cycles left for operating hours, test/maint, gasket, and the motor.
Activate wiper—Initiates the wiping action of the wiper.
Signals—displays the signal outputs for the device.
Output mode—Select the behavior of the instrument outputs (Hold, Active, Transfer, Selection)
Reset setup—Resets all user-editable options to the factory defaults.
