Annex B/C selection boundary
Use this tester when the ISO 80369-20 selection question is pressure leakage or positive-pressure liquid leakage. If the inquiry names subatmospheric-pressure air leakage, route it to Annex D instead; if it names axial separation, route it to Annex F.
KingPo documented pressure test workflow
KingPo supplied documentation instructs the operator to place the device on a stable desktop, connect power, turn on the power switch, select the touch-screen Pressure function, install the test sample, set test time, test pressure and sample volume, then start the test.
Touch-screen fields and calculation inputs
KingPo supplied documentation names the live pressure, test time, P1 pressure at the test time, leakage rate, starting pressure, pressure change, volume from valve to specimen and test period as working fields. These are shown as operating context; final judgment limits stay tied to the applicable standard and order-specific confirmation.
KingPo documented positive-pressure liquid workflow
For pressure liquid testing, KingPo supplied documentation describes closing the liquid tank valves, connecting the test sample and AIR OUTLET line to the tank valves, filling the funnel until water flows from the sample end, blocking the sample outlet, opening the air valve and starting the test.
Additional setup and documentation notes
Software and reporting evidence
KingPo supplied documentation names live pressure, test time, P1 pressure at test time, curve display and print report controls. Public copy records those functions as operating context; final report field wording is confirmed during quotation.
