◆
Wait time: Stabilization time at the set point. After this countdown is finished the test will begin.
◆
Test time: After the wait time is finished, the calibrator will stop control and be in standby mode. During the test time
the calibrator will monitor the drop from the start pressure (Start P.) to the ending pressure (End P.) and the change
in pressure or leakage is determined.
3. Run
◆
Internal high/low range
1) Press / to start to pressurize to the set point and wait for the displayed pressure to stabilize.
2) The 761 will continue to control and the wait time will count down.
3) When the wait time reaches zero, the calibrator changes to the Standby mode and records the displayed
pressure as the start pressure.
4) The test time will count down, Real leakage = Start pressure - Real pressure.
5) When the test time reaches zero, the calibrator records the displayed pressure as the end pressure, and then
reduce the system pressure to near the atmospheric pressure.
6) Finally Leakage = Start pressure - End pressure.
7) By pressing the / to pause or continue during step 1), 2), 3), 4), the run mode will be changed
between the Standby and Control in step 1), 2).
◆
External pressure source
1) Connect to an external pressure module.
2) Pressurize to the leak test point with an external pressure source.
3) Press / to start to run and record the displayed pressure as the start pressure.
4) Start test and the test time will count down, Real Leakage = Start pressure - real pressure.
5) When the test time reaches zero, record the displayed pressure as the end pressure.
6) Final leakage = Start pressure - End pressure.
