¶ 2. TOMOTA A3 MACHINE BATTERY VERSION
- The Tomota A3 device's battery compartment necessitates three batteries, which will be installed beforehand. Battery information: BRC 18650 - 3.7V Li-ion.
 |
 |
- The TOMOTA A3 device has the charger and batteries included. The charger can be used with a power source that ranges from 100-240V.
- The battery should only be replaced when the light brightness dims, the battery deforms, or becomes hot. Replace the battery after 6 months of use to guarantee optimal performance.
- The steps to replace the battery:
1. To loosen 2 screws, turn them to the left. Remove the battery door from the bottom of the machine.
 |
 |
2. Insert three BRC 18650 - 3.7V Li-ion batteries, ensuring the correct alignment of the + and – marks. An illustration showing the batteries in place is provided.
 |
 |
3. Turn and tighten the screws to the right, securing the battery cover back in place.
FUNCTIONAL DESCRIPTION
¶ START-UP
- Access the TOMOTA mobile app installed on your phone to use the analyzer's features;
- Log in to the TOMOTA mobile app (or you need to create an account before you can start measuring);
- Start a Water Quality Analysis in the mobile app;
- Calibration of luminaire conditions is set up depending on the needs of the user (can be omitted and should be the default mode, because modification can be affecting the accuracy of the results);
- Set the parameters to be analyzed.
¶ 12 WELL PLATE
The machine is provided with 01 units of 12-well plastic plate.
When the wells are filled with sample and reagent solution. To place the plate in the capture chamber, follow these steps:
- Open the cover of the capture chamber;
- Orient the plastic plate so that the arrow mark is aligned with the arrow mark located inside the capture chamber;
- Using light force, push the plastic plate over the corner of the calibration bar and downward until it touches the edge of the glass plate containing the calibration bar;
- Sample is ready to be analyzed.
Warning: Placing the plastic plate in the wrong direction will affect the results as well as the water quality parameters measurement.
¶ COLOR CALIBRATION BAR
The machine is supplied with a color calibration bar.
The color calibration bar should be pasted or replaced in the correct position marked on the glass plate containing the calibration palette.
Any stains or external factors that change the condition of the calibration palette should be removed immediately or replaced with the supplied calibration palettes.
¶ USB CAMERA SETUP
Plug the USB camera cable into the phone to start the camera and set up the phone as the power supply and intermediate device for the Tomota A3 (display, image retrieval, and data processing).
¶ PRECISION AND ACCURACY
Precision refers to the extent to which independent test results fluctuate around the mean. Accuracy is defined as the closeness of the test result to the true value. Generally, good repeatability is associated with high accuracy, but there are exceptions. See the picture below to understand better.
Accuracy = Precision + Trueness
