2.
Select the appropriate sensor if more than one is attached and confirm.
3.
Select Calibration and press confirm.
4.
Select Output mode. Select the available Output Mode (Active, Hold, Transfer) and
confirm.
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
and 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
.
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
