zuzu85 Posted June 19, 2022 Share #1 Posted June 19, 2022 Advertisement (gone after registration) Hi guys, I’m a bit embarassed to say this, but I’ve dropped the leica mr-4 and the needle release button doesn’t go back to its position after I press it. I tried to wiggle it a couple of times but to no avail. Did I accidently break it? Link to post Share on other sites More sharing options...

So it’s just the needle release button doesn’t spring back after pressing it. Link to post Share on other sites More sharing options...
jerzy Posted June 21, 2022 Share #5 Posted June 21, 2022 on MR and MR-4 both Test and Measure buttons do release the needle. Does either one do it on your broken MR? I understand that the needle is now deflected and locked. Remove battery and try either button to get needle back to zero position. If it does not that there is indeed something broken inside.

It’s the needle release button ( the button that you push to meter the light). When you normally press that button to meter the light, it jumps back to its position after you remove your finger from the button. Now it doesn’t do that anymore, it just stays stuck and I have to push it manually back to its starting position. cheers Link to post Share on other sites More sharing options...
jerzy Posted June 22, 2022 Share #7 Posted June 22, 2022 Advertisement (gone after registration) Hi, yes, I wrongly understood... Well, you will need to take off the cover to see what happened. There were instructions in Forum here how to do it, but shortly: 1- remove the screw holding discs (screw with 2 holes), remove the discs; 2- remove 2 screws beneath; 3- remove 2 screws on the short side of cover, below the measure button; 4- move Test button into test position and lift off the cover. Measure lever on the cover does not have any spring, it is pushed back by the black slider. If the cover is bent the spring in slider is to weak to push back the lever Welcome, dear visitor!

I tried to open the top disk with the two holes with a plier but that doesn’t. What kind of 2-point spanner is recommended to use? Link to post Share on other sites More sharing options...

ironringer Posted June 22, 2022 Share #10 Posted June 22, 2022 Following Jerzy's lead, I made myself a simple tool for opening the top 2-hole screw. I used a relatively thick-strong staple, bent its ends to the correct spacing to fit the holes, filed the tips down so they are flat (to dig into the screw holes), and held that 2-pronged staple with pliers. It unscrewed the top screw easily. Note when you re-assemble the meter, do not tighten the top screw too much - it is meant to be a friction fit, not a tight mechanical fit. 1 Link to post Share on other sites More sharing options...
ironringer Posted June 22, 2022 Share #11 Posted June 22, 2022 Correction - I used a small paper clip to make the 2-tipped tool, as in the pictures below. The paperclip metal is stiff enough to apply adequate torque, when the pliers are held close to the tips. Simple but effective. Welcome, dear visitor!

zuzu85 Posted June 23, 2022 Author Share #12 Posted June 23, 2022 Thanks guys, I’ll try a paper clip and see if I manage. The way to loosen the top disk is by turning it anticlockwise right? Link to post Share on other sites More sharing options...
zuzu85 Posted June 23, 2022 Author Share #13 Posted June 23, 2022 I bought this and I just used that to open the top disk. 1 euro tool.😬 Welcome, dear visitor!

ironringer Posted June 23, 2022 Share #14 Posted June 23, 2022 Good idea; is the tip spacing correct for the holes? It looks too wide. Link to post Share on other sites More sharing options...

Actually I could bend them with my fingers to decrease the spacing. Whatever works right… Link to post Share on other sites More sharing options...
