9.1 External Exhaust Valve (Separately Sold)
Water, oil, or other foreign matters inside the tested parts may get into the air leak tester when it exhausts air,
which may damage the tester.
Installing an External Exhaust Valve between air leak tester and tested part prevent the contamination.
9.2 Bypass Circuit Unit
Test time can be reduced by using a Bypass Circuit Unit when testing tested parts with a large internal
volume with low test pressure because it fills the parts with air in a short period of time.
Models with the option B are equipped with a pilot pressure port for the Bypass Circuit Unit.
Air leak tester controls the Bypass Circuit Unit.
Enable the Bypass solenoid valve to use it.
Go to: > Main Menu > Settings > Advanced Settings > CHG Options > Bypass Valve
