Q. would like to purchase the Tm-20a Digital Stopclock, can I have 2 external light gates first one for start timing and second gate to stop timing?
A. Hi Rocher, thank you for your question. This can be done via the terminals on the front of the stopclock. The trigger will need to be a switch closure.

Good function but a bit lighweight

Works fine but front plugs for timer leads are a bit lightweight. They need more solid retaining nuts inside.
