Tap the discovered LT-635 series sensor to connect to it via Bluetooth. The uPyxis APP can identify the
sensor type if multiple Pyxis sensors are discovered in the scan.
As shown in Figure7, when connected via the MA-CR Bluetooth adapter, the uPyxis calibration page will
display the current suspended solids concentration value being measured by the LT-635 sensor connected.
Four functional tabs are available in this page: Deionized Water Calibration, Mid-Range Calibration, High-
Range Calibration and Restore to Factory.
4.1.1
Calibration by uPyxis Mobile APP
Deionized Water Calibration Process - Remove the LT-635 sensor and rinse it thoroughly with deionized
water. Repeat this rinse process three times. Wipe the sensor with a dust-free cloth or paper-towel to
confirm that the sensor is free of obvious impurities. Insert the sensor into a beaker. Inject bubble-free
deionized water into the beaker and wait for the sensor reading to stabilize. Click the “Deionized Water
Calibration” button after the reading stabilizes. If the calibration is successful, the interface will return a
message "Calibration Succeeded" as shown in Figure 9. If the calibration has failed, the interface will
return a message "Calibration Failed", as shown in Figure 10 and the user must repeat the process until
calibration success is achieved.
