The unit will store 4 different measurements at programmed time (standard values are: 10, 60, 120 and 120 second).
See paragraph 10.2.4 to change these values.
The instrument will display the

∆P (P1-P4) value and it compute, using the circuit specifications (Length, Diameter and

Type) the test result (GOOD or FAIL).
Test result will be calculated using the following acceptance limits table:
