Simple to follow Gossen Luna Pro instructions?

That's for the Luna Pro SBC. The regular Luna Pro is a lot different.

Here's the manual for the original Luna Pro

If you have the Luna Pro S, you need the above manual AND the Supplemental Manual that covers the changes in the Luna Pro S.

Note that the Luna Pro was designed to be used with mercury batteries that are no longer made. If you put Alkaline or Silver Oxide batteries in it, it will give incorrect readings. The Luna Pro S was being made when mercury batteries were banned, so Gossen created an adapter that takes silver oxide batteries and reduces their voltage to that of the mercury batteries the meter was made for. It was included with the Luna Pro S meters that were made after the mercury ban took effect. Not all have it, since some Luna Pro S meters were made before that. For people with the older Luna Pro and the S version that did not have the adapter, Gossen sold it separately. You'll need one to make the meter work.
 
I was lucky to have a Luna Pro S with the adapter for SR44 silver oxide batteries. The Luna Pro S with the adapter has very straightforward instructions printed on the back of the unit. Gossen produced a new /better adapter sometime later due to customer demand.
 
I have two of the original mercury-cell Luna Pros: my original one I bought new in 1986 and a brand-new-looking (but older) one I picked up here in the RFF Classifieds. Unfortunately I only have one adapter, so I have to move it to the other meter on the rare occasions I switch.

Admittedly, I only use a small portion of the meter's features. I use it to measure how many f stops away from "Sunny 16" full sunny daylight I'm at. Two stops? Three stops? For that it works great but for reflective metering I use a Sekonic or a Pentax spotmeter.
