Default Help me to understand how this HoldPeak HP-990B smd tester works

Hi can anyone explain how it works with smd tests the one I have a tweezer is called: HoldPeak HP-990B.
I would like to understand if you test a component, for example a capacitor in continuity mode, then this should beep if it is open or short, otherwise it is "OL" that applies or ???

Read the manual, it explains all the modes and what they do, and at what resistance the continuity test beeps.
Here is the manual, isn't GOOGLE a wonderful tool
