Concurrent and sequential test sequencers are available in the Isaac HD and 7i.
Concurrent testers run a single test on multiple channel outputs. Each channel has an independent set of test pneumatics and pressure sensors. Pressure and Vacuum Decay can be used on concurrent models.
Sequential testers have a single sensor that is routed to test through one of four channel outputs, testing only one output at a time. The channels that are idle during test are naturally vented to atmosphere, allowing for cross-wall or inter-lumen inspection. All test types except Crack can be ran sequentially.
