Meter movement for Simpson 260?

Have you tried

Aidan Grey

If it is just the glass, then that is simple to replace by making a paper pattern and going to a glass shop with the pattern (*NOT* the meter!!). If the needle is partly bent, it can be straightened out - but do it slowly and carefully; *NO* sharp bends, else may break the metal.

I have a spare glass and trim ring for a simpson 260, Series 5P.

He can probably get a whole new meter/front panel assy from Simpson electric. They still make the 260,don't know about the Series 5P. IIRC,they're up to Series 6 now.

They have a website,Google for it.

He also might try emailing them and see if they can replace the broken glass,if his meter movement is not screwed up.

Great idea! What was I thinking, giving away something he can still buy?

I'm a "she" dear. :)

I just reread this message and went and checked it out with my meter. I had to carefully break the busted glass out of there, and guess what. The meter movement still works! Yay!

Now I guess, all I have to do is remove the movement and take it to a glass shop and have them cut me a little piece that fits it. I can bring a shard of the broken glass so they can see how thick it is.

Be very careful with the movement when it's out or exposed in any way. There is a magnet in there, and these tend to suck in minute ferrous bits which can keep the meter from moving. You want to be absolutely sure that you don't ever put the meter down somewhere that it has ANY chance of picking up something like that.

My technique is to lay down a clean white piece of printer paper and set the meter movement on top of that, right in the center. If you're going to leave it for any period of time, place another clean sheet on top of it. Never bring any tools near the movement until you first carefully check the tool tips for clinging bits of ferromagnetic dirt.

Ok, thank you.

Something else you might consider is *not* using glass, but instead using polycarbonate or some other plastic. I recently repaired a photographic light meter this way using 0.030 material that I got from Micro-Mark. It's not too difficult to cut using the score-and-break method, and you can do find shaping using sandpaper or a sanding wheel on a Dremel tool. I held it in with a thin bead of RTV. The beauty of plastic is it won't break - but it will scratch more easily than glass.

It can also accumulate a static charge and give false readings, or even cause the needle to stay somewhere in the middle of the scale. You have to be careful of what plastic you chose.

I still have several spare pieces of the meter glass from dead 260 meters if you want one. E-mail me with a mailing address and I will send one to you.

Yeah, I just went to a glass shop with the front part that holds the glass and a shard of the old glass so they could gauge thickness. $5. It's fixed. Thanks a lot guys! :)
