Calibration
4.6 Calibration
There are two calibration techniques; depending on whether turbidity or suspended solid
is required (refer to section 4.6.2 or section 4.6.3 on page 8). Before calibration, determine
the behavior of the 4–20 outputs and alarm relays while the user is in the Calibration menu
(refer to section 4.6.1).

Settings
Name Enter up to a 10-digit name in any combination of symbols and alpha or numeric characters.
Parameter
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.
Unit
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.
Cleaning interval
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.
Response time
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
Data logger interval
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
Reset Resets all user-editable options to the factory-defaults.
Test/Maintenance
Sensor information 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.
Wiper Select Profile Counter to display the number of wipes made (from 20000 backwards). Select
Reset Config to manually reset the profile counter.
Counter Shows the number of hours or cycles left for operating hours, test/maint, gasket, and the motor.

4.6.2 Calibration for Turbidity
Turbidity calibration requires the use of a Turbidity Standard Solution. The manufacturer
recommends the 800 NTU Turbidity Standard Solution (part of the calibration kit No.
57330-00). A zero-point calibration using deionized water is also recommended.
1. From the Main Menu, select Sensor setup and press confirm.
2. Select the appropriate sensor if more than one is attached and confirm.
3. Select Calibration and press confirm.
4. Select Sensor measurement and confirm.
5. Place the sensor in the calibration cylinder with deionized water, mounting it with the
supplied clamp. The tip of the probe should be approximately 1-inch below the surface
of the water. Record the reading from the sensor measure display.
6. Select Offset. Multiply the reading obtained in step 5and enter the value.
7. Select Sensor measurment.
8. Rinse the outside of the StablCal®800 NTU standard with water to remove any dust
or debris adhering to the surface of the bottle. Gently invert both StablCal standard
bottles a minimum of 50 times. Remove the lid and seal from each bottle. Slowly (to
avoid creating bubbles) pour the contents of the bottles into the calibration cylinder.
Immediately place the tip of the probe into the positioning bracket in the calibration
cylinder. The tip of the probe should be approximately 1-inch below the surface
standard. Allow the reading to become stable on the SENSOR MEASURE screen.
Record the value (measured value). Calculate the factor. Refer to section 4.6.2.1.
9. Select Factor to display the corrected measurement.
4.6.2.1 Calculating the Factor
For example, if a sample measures 750 NTU using the sensor and the standard is
800 NTU, the new factor would be calculated as follows:
New Factor = 800 NTU Standard
measured value
New Factor = 800 NTU = 1.07
750 NTU

Calibration
4.6.3 Calibration for Suspended Solids
Suspended solids calibration requires calibration to the actual sample. This optimizes the
compensation for the particle size and shape typical at a measuring site. It is best
performed by mounting the sensor as usual for normal measurement, and then grab
samples collected and evaluated by laboratory methods. While a single point calibration is
usually sufficient to provide accuracy, the SOLITAX does offer the ability to calibrate with
up to 5 calibration points.
1. From the Main Menu, select Sensor setup and press confirm.
2. Select the appropriate sensor if more than one is attached and confirm.
3. Select Calibration and press confirm.
4. Select Settings and confirm.
5. Select the number of points desired for calibration (the unit with linearly interpolate
values between calibration points). Select Factor for a single point calibration.
6. Mount the sensor as is during normal operation. Alternatively, place the sensor in the
calibration cylinder (or a container with dark, non-reflective walls) 2 inches of
clearance from the probe face with the probe face submerged by 1 inch or more.
7. Select Sensor measurement and record the reading.
8. Immediately take a grab sample. Determine the total suspended solids using a
gravimetric method such as Method 2540 D in Standards Methods for the
Examination of Water and WasteWater.
9. Calculate the new factor. Refer to section 4.6.3.1 for single point (Factor) calibration.
Refer section 4.6.3.2 on page 8 for multiple point calibrations.
10. Select Factor and press confirm. The corrected measurement should be displayed.
4.6.3.1 For Single Point (Factor) Calibration
Calculate the new factor:
For example, if a sample measures 2.3 g/L using the SS sensor and the gravimetric value
was 2.0 g/L, the new factor would be calculated as follows:
4.6.3.2 Multi-point Calibration
1. Repeat steps 6–8in section 4.6.3 on page 8 at different times to obtain different
measurements.
2. From the Settings menu, select the appropriate calibration point menu.
3. Enter the pairs of values for each reading, the target value being the laboratory
determined value, and the actual value being the reading that the SOLITAX produced
in step 5. The pairs should be entered in order from lowest values to highest.
New Factor = Determined gravimetric value
measured value
New Factor = 2.0 g/L = 0.87
