Q1: The timer does not display after power on.

Timer

A1: After you pressing the START button, the air pressure in the test chamber rises slowly. When the set air pressure is reached, the test will start, and the timer will display and start counting down. See the figure below:

Timer started

After the set test duration ends, the timer will go out again.

Q2: What is the function of air compressor?
A2: JL-8 Waterproof test equipment needs to be used with air compressor, and you need to prepare it by your own (see the user manual for air compressor parameters).
The air compressor has two functions:
1. Used to increase the air pressure in the test chamber during testing to simulate deep water pressure.
2. The top cover of the chamber is heavy. When the top cover of the test chamber needs to be opened, use the air pressure of the air compressor to open the top cover.

Q3: How to confirm the test results?
A3: Take out the sample, wipe the water on the surface, and then open the sample to check whether there is water inside. If there is water inside, it does not meet the standard.
