Wrong Values and/or Color Charts

Firstly, it's crucial to understand that the color chart generated by the device is in real time. It's not generated based on the specific test, nor is it an automated chart. 

Here are some common scenarios and how to address them:

1. All White Colors on the Chart:

- This can depend on the nature of the test. Some colorimetric tests do indeed display a white (transparent) color that corresponds to certain values.

- In titration tests or tests without a clear water value, an all-white chart usually indicates that either sample water did not enter the mixing chamber, or no reagents were disposed in the mixing chamber. 

- To resolve this, ensure all vials have sufficient reagent volume inside (50% in v1 devices, 34% capacity in v2, lab, and pro). Also, check that the syringe isn't clogged. If the issue persists, run a test chamber calibration to confirm the water is entering the mixing chamber.

2. No Color Change in Titration Tests:

This can occur for several reasons:

- Insufficient titrant.

- Absence of a stirrer magnet in the mixing chamber.

- Improper rotation of the stirrer motor.

- The reading might be outside the range of the test kit used.

3. Darker Colors than Usual:

- This is likely due to insufficient sample volume. Calibrate the testing chamber and ensure the dosing syringe isn't pulling in air bubbles with water in ReefBot Lab or Pro. 

4. Shifting from Endpoint Color to Base Color:

- This indicates that the reagent positions have been swapped on the mobile app or on the device. 

5. Pale Colors:

- Check if the stirrer motor is operating correctly. Also, confirm that both reagents and chambers contain stirrer magnets.

- Another potential cause is that the reagents need to be returned to their bottle and thoroughly shaken. This might be due to some crystals in the original bottle settling at the bottom of the bottle and not dispensing properly into the vials.

- To avoid this, you can run scheduled stirring tests for tests that are not tested daily. From the main dashboard, click on "Schedule" on the top center and follow the steps, best to schedule the stirring test at night or whenever the device is not testing.

By keeping these troubleshooting tips in mind, you'll be better equipped to navigate any issues you encounter simply by looking at your color chart generation.
