can cause the vacuum level to rise in a system giving a false positive during a leak test when no

leak is present.

Pressure Hold Mode – Pressure Decay Test

Overview:

The P51-870 TITAN® can be used to monitor a system leak through a drop in positive pressure.

The pressure decay test displays the current system pressure (Pc), the initial pressure (Pi), the

change in pressure (Pi-Pc), the Limit Pressure (Limit), and the Rate of Change (%/min).
