Mid-Range Calibration Process
–
After completing Deionized Water Calibration, remove and insert the LT-
635 sensor into a clean and dry beaker and inject the midpoint calibration solution.
*NOTE*
The midpoint
calibration solution can be process water of the application itself, with a verified Total Suspended Solids
(TSS) value in the range of 2,000 to 10,000 mg/L. The recommended method of TSS verification for the
calibration solution being used is Gravimetric Total Suspended Solids determination.
Wait until the reading
stabilizes and then click the Midpoint Calibration button to calibrate the midpoint, as shown in Figure 11.
If the calibration is successful, the interface will return a message "Calibration Succeeded". If the
calibration has failed, the interface will return a message "Calibration Failed" and the user must repeat
the process until calibration success is achieved.
High-Range Calibration Process - If the high range calibration is not required (>10,000mg/L), the user does
not need to calibrate the high range. To continue with the high range calibration after completing Mid-
Range calibration, remove and insert the LT-635 sensor into a clean and dry beaker and inject the High
Point calibration solution.
*NOTE*
The high point calibration solution can be process water of the
application itself, with a verified Total Suspended Solids (TSS) value in the range of 10,000 to 30,000 mg/L.
The recommended method of TSS verification for the calibration solution being used is Gravimetric Total
Suspended Solids determination.
Wait until the reading stabilizes and then click the High Point Calibration
button to calibrate the highpoint, as in Figure 12. If the calibration is successful, the interface will return
a message "Calibration Succeeded". If the calibration has failed, the interface will return a message
"Calibration Failed" and the user must repeat the process until calibration success is achieved.
