Check that the +/- stops offset is set to zero and not 2. Check the EV measure. Sunny 16 implies an EV of 15, maybe 14 or 16 depending where you live.

I removed and changed the lumisphere to a viewfinder. This changes it from an incident into a Reflective light meter. The EV numbers were coming out at 3,4 or 5 at most

But incident and spot meters have different software algorithms. I was surprised that reviewers of the spot attachment aren't reporting more problems. There is a warranty if you bought it directly, maybe you got a faulty one or it is not compatible with your particular model.

Sekonic have come back with answers - an optical portion is broken and the wire for switching measurement mode (Incident / Reflective) was also broken.

Cost is only ￥9500 about £65 so in the end not to bad and definitely worth the repair.

Thanks to all for all your help..

I'm impressed by how fast Sekonic got back to you with its diagnosis and with the reasonable charge for the repair
