I’m not sure everyone knows about this, but I found it by accident.
As a newbie, we don’t get taught how these work whilst learning, more on the job, but this will give a good idea of what to press. It wont tell you the infringments, or which way to put the card in, but gives you an idea of what its looking for… (always check what your employer wants as well!)

Good find! Thanks for posting that.
I’ve found one for VDO tachos too, but it’s an Android app, would be more useful to have one for a laptop
