Maybe with age the meter is off a little, or you decide to use a 1.5 volt battery.
Well this is what you do.
Remove the bottom plate. Inside you will see the battery compartment, next to it is the meter galvenometer. On top of it is usually a piece of insulating tape, remove it. Now take a sharp point and scribe a line across the edges where the circle meets the housing. This is your reference point.
Picture #1 shows the two clamping screws, loosen these just enough, to where the center section will turn.
Picture #2 shows the notches in the housing. Use one to turn the center section in the direction needed. Counter clockwise for less exsposure, clockwise for more exposure.
Now you're asking, How in the world do I provide battery power?
Picture #3 shows my solution. I took a battery holder from a C-35 and a couple of pieces of wire. I then made a loop on the positive lead and an alligator clip on the negative lead.
Using one of the bottom plate screws, fasten the positive lead to the frame.
Place the alligator clip on the negative contact of the battery compartment.
Now you have power. Use a known accurate meter source, another camera or good light meter. Use natural light, not real bright, nor dim.
Turn the galvenometer until the RC meter matches your known test source.
Then carefully tighten the clamp screws. Recheck.
OK? Now remove power leads and replace the tape on the galvenometer. Reinstall the bootom plate. Insert battery.
Best part. 😀 Pour a large glass of focusing fluid and relax.
