To do a leak test on a pressure system:
1. Connect the instrument (Figure 3) and, if necessary, adjust the Set Up (Table 1).
2. Select an applicable leak test from Select Task (Table 2/Table 3) and, if necessary, adjust
the Settings (Table 4).
3. Set the period for the leak test (Table 4).
4. If necessary, do a zero correction (Table 4).
5. To start the leak test, select Start (). When the test is finished, the instrument calculates
the leak rate in the applicable units/minute.
