7.4.1 Leak Test Performing
1. Connect to air circuit
a. Connect the device to the air circuit;
b. Click the start icon at the bottom of the screen, apply pressure to the leak test point;
c. Start counting down the waiting time, and record the real-time pressure at the end of the waiting time as the initial
pressure;
d. Start the test, count down the test time, and start to calculate the real-time leakage, real-time leakage = initial
pressure-real time pressure;
e. Record the pressure at the end of the test time as the end pressure;
f. The entire leak detection process ends, and the final leakage = initial pressure - end pressure;
