Maintenance and Calibration
Maintenance
When it is not in use for a long time, please detect it with water, so that the corrosive brake fluid can be removed vertically from the test stick and dilute the corrosiveness, and then leave the heating stick to dry in the air at room temperature.
Calibration
Fill the beaker with water and test if the boiling point is at 100 °C (212 °F) ± 3 %, and make a quick initial diagnosis of whether the tool is working properly. If more rigorous standards are required, it must be returned to the factory for re-testing and calibration.
NOTE
If the same brake fluid sample is tested continuously and the data varies, this is normal because the test sample has been boiled and the structure has changed.
Please read this manual before the first use
Please wear goggles when working and be careful not to splash brake fluid into your eyes
Do not perform the test without sufficient liquid in the beaker (the test stick can be damaged by empty boiling)
Do not touch to avoid burns after the test, as the test stick and liquid are at high temperature.
Do not pour the brake fluid back into the reservoir as the structure of the fluid has been damaged and the boiling point has been lowered, otherwise, it will affect driving safety.
After the test, please empty the brake fluid and fill another 50ml of water to test the boiling point in order to clean the residual brake fluid of the test stick.

After entering the "NORMAL" mode, you can use the "T" key to switch the brake fluid types (DOT3, DOT4, DOT5); then press the "S" key to select the required fluid type. | After selecting a fluid type, it will enter the ready interface, which displays the reference dry and wet boiling points and battery voltage of the oil product. | when the ready page is displayed, press and hold the "S" key, the progress bar starts to read, and the TMP displays the live temperature value at the same time | After the progress bar is full (about 16s), the screen will display the final test result. It can be used to judge whether the brake fluid needs to be change |

Why the actual boiling point is lower than the detected boiling point
The typical working temperature of brake calipers is about 150°C~200°C. If the boiling point of the brake fluid is detected to be 180°C when the brake fluid is taken out from the mouth of the reservoir, the brake fluid caliper point is actually only about 155°C, because the rubber tubing easily absorbs water, resulting in a large difference.
How to prevent/remove vapor
In fact, it is impossible to completely prevent vapor from entering, so vapor will enter the brake fluid from the brake fluid reservoir cover, rubber hose, and connector gap.For the majority of cars, vapor increases by about 2% over a year, and this alone can significantly affect brake fluid quality, so it should be taken seriously.
The only way to remove water vapor is to use twice the amount of brake fluid. One bottle is used for rinsing to remove residual vapor in the pipeline, and the other bottle is used for adding and refilling the pipeline.
