a. Connect the device to the gas 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;
2. The whole process will be displayed in stages in the leak curve at the bottom of the screen.
7.3 PSV test
The calibrator provides function of PSV test, to test the safety pressure of the safety valves. Click the pressure module
on the top, to set relevant parameters, see table below:
Table 39 PSV test setting
