How to use Incident Light Meter?

Hi all,

I have got an incident light meter from ebay. It is a Weston Master Universal Exposure Meter Model 715. But I have no idea how to use it. Please can you experienced photographers tell me how to?

Thanks.

If I'm not mistaken that is Weston Master II (two). It is a reflected light meter, not incident light meter. Here is a link to instruction manual:

You might run into a bit of a challenge with this meter. I seem to recall that film speed is not ISO/ASA, but Weston numbering system. Wikipedia can help you with conversions. Other than that I've been quite satified using Weston Master meters (the III model) in the past.

Thank you BrianShaw for your info.
