I ended up buying a couple meters from that auction site and spent last night calibrating the first one that has already arrived. While the information I found on the model 269 indicated 1 mA full scale, a rig set up with a 1.5v battery and linear pot gave me something on the order of 50 mA full scale. Hmm... the meter moves smoothly and the scale on this particular meter is - surprise! - 50 mA. Perhaps this particular meter was an earlier version or a modified example with a different sensitivity.
In any case, I am able to remove the outer cover and can see the scale plate is held by two screws. Should be a simple matter of swapping out the scale plates and moving along with the project. A learning experience, to be sure.
Happy New Year to All!

Season's Greetings from Minnesota, where it is currently snowing.
Today's question is about the beautiful Weston 269 meter. Does anyone have any experience in changing/replacing the background scale? I have a pair of meters, each with a DC volt scale ranging from 0 to 500. Unfortunately each of them has been blown (I will spare you the sad details).
I see several for sale on eBay but they are scaled for mA or dB so I would need to change them somehow. Luckily I can take my blown meters apart for trial purposes but I would be grateful for some advice as to the proper method.
Alternatively, if someone has a pair already scaled to 500 VDC and is willing to part with them I would be very interested in arranging a purchase.
Thank you very much in advance for your suggestions. Happy Holidays!
