A handy gadget and fully explained. Thanks.

You can use a trigger board (with the necessary cables and adapters), to get higher voltages via PD and QC for your testing.

A great application for these variable loads is to accurately gauge battery strength. Even dead batteries after all have voltage. You could use anything even a bread board with a varistor you don't need to spend $50 USD for this gadget. But it's cool to observe these necessary experiments to understand fundamentals to electronics. Watch an electrical engineer send 8 hours to troubleshoot a variable speed motor drive. It's easy to become bogged down in theory then call a trainned electrican and the electrican will have the item repaired with no schmatic and only a VOM. Very interesting and for the intended scope, and small dimensions very effiecient device.

This is a very good tester. However, the bottom of the tester circuit board is exposed to being inadvertently being shorted out on something conductive .. I mounted it to a blank perf board, via threaded nylon standoffs, to avoid shorting it out.

Good demo but that tester is pretty much obsolete now.
