Gossen Pilot "Zero Setting"

[Shesh]

I just received a Gossen pilot light meter which I bought on EBay. It is very easy to learn to use except for one little screw behind the light meter which says "zero Setting". From that, I assume it is a screw you turn to calibrate the meter. so, what I would like to know is: What exactly does the "zero setting" do and if it is indeed meant for calibrating the meter, How would I go about it?

As always, Thanks!

Isn't that screw a "dfw" screw? (Do not fool with)

I just read the acrobat file veriwide mentioned above. It implies that the screw is for calibrating the meter and also mentions that the meter rarely would need calibration. I will compare it with the metering in my N90s and see if they match up and decide if I need to touch the screw. I plan to use the meter with a Bronica S camera that I am planning to buy.

Now what happens if it's the N90 that is off? I go with not fooling with it.

It does not matter if the N90s is off, as long as the meters are consistant, I will know how to compensate in order to get consistant results. I will tread VERY carefully, thanks to all your advice.

Just tested the meter with the N90s. I used a uniformly lit wall as the subject. The readings were identical. So, no need to DFW (thanks for the term, lee) with the screw on the meter.
