My meter was 3 stops off, I was ready to buy a new meter or find someone to repair it. I can't believe it but this actually worked on my meter. Thanks so much for this trick/tip or whatever you want to call it.

Thanks! Worked like a harm and prevented me dumping it again on ebay , :-) This little switch is to reduce the sensitivity of the meter by 3 stops if you use the darkroom attachment which is the adaptor with the plain hole in it so no optics in the adaptor. If the switch gets dirty it puts the meter in darkroom mode for the adaptor and so without the adaptor the meter is 3 stops off. A good reminder to NOT put this(or any other measuring device) in your pocket with lint and dirt but to keep it safe and clean in the pouch.

After 15 years in my closet, my autometer IV f which was 3fstop wrong, i found yout post on youtube and i tried it.....it made me smile!!!!! :) Thank you!!!

I came across this tutorial on youtube today. This worked great with my Minolta IVF autometer. Many thanks.

Thank you! It worked. I was planning to do all kinds of calibration procedures because my minolta v was way way underexposing. I came across this video and thought that looks too easy, probably won't work, but I gave it a try and the meter now works like a charm. Thank you!

This is, without a doubt, the coolest tip I've ever seen on the internet. I just bought a used IIIF to get into studio photography cheaply. I was dismayed when it showed 3 full stops off, and I couldn't figure out what I was doing wrong. After finding this tutorial, I opened the back of the head up, and it has a similar connection, which I cleaned with a five dollar bill, figuring that a fiver would be more effective than a single...;)...and, it worked like a charm. So add the IIIF to this tutorial, as well, as it works the same way for it (the contacts just look a bit different, but they are in a similar location). I don't know that this is really a "calibration", as it's more in the nature of a maintenance fix, but who cares? It just works. Thanks for taking the time to post it.

also work with Auto Meter III :D

Wow, I was ready to buy a new meter before I ran into this video. Set screw would not provide enough adjustment before I performed this dollar bill trick. Worked like a champ!

So i just found this thing in my dad's desk, and i was thinking like, "damn this thing looks really cool i think it's a prop from a sci fi movie" but now i know the thing it's just an auto meter

Holy crap it worked! I still needed to tweak mine a little with the calibration dial in the battery chamber to get it spot-on, but it went from useless (off by about 4 stops) to perfect! Amazing. Thanks!!

LOL! This works! Probably not "calibration" per se, but it does apparently reset the meter to read "normally." Before I did it the meter was giving me f8.0 at 1/60 and ISO 400. Afterward I got f2.8, which matched my Fujifilm X-T2 spot metering a grey card. Over 20 year old Auto Meter IVF works like new!

Thank you very much! My two Minolta Auto Meter IV F now are fine.

Amazing. The contacts do not actually "touch" but the readings are different after this trick, and now they match my Sekonic L-558 in spot mode (I've lost my dome on the Minolta unfortunately). I think it has everything to do with static charge that is making the readings off, but I wonder if the rubbing is actually causing the static charge, or neutralising it.

Thank you. You saved my IV F

Holly Cow, this works! You just saved me $100+. Many thanks.

i´ve got this meter, to be used with the sinar booster 1. meter was 3 stops of, but the method shown in this video just works! now, it´s +0,1EV compared to my 758DR. thanks a lot!!!

I have no idea, but it works... I have done over a half dozen this way. They were 4-5 stops off and it calibrated them to within 1/10 of a stop from a good meter. I had been taught to do this from a colleague.

I did it and it's worked even with a 20 euros! This is not a calibration but my Autometer had a 3 stop underexposed and now it is ok. Maybe is a fail in electric contact because lack of use.

I bought a second-hand Minolta AF IV meter and noticed right away that readings are not ok: put the meter readings to the camera and get 2-3 stops underexposed images. Google brought me here and now I have a fully working meter. TVF8 - I owe you a beer :)

My meter hadn't worked correctly for years. I tried a few other methods to re-calibrate to no avail. I didn't expect this to help at all , but decided "What the h----,. and tried it. It worked perfectly immediaitely.

Absolutely brilliant- Thank you so much !

Fantastic! it works! Thank you soo much!

Thank you!! You're AWESOME!!

tried it the first time, didn't work. Then I took it apart, cleaned that area with an eraser, put it back together...worked like a charm. I have a feeling the dollar bill cleans that area. Mine was a bit more dirty from the sea salt as I do a lot of weddings at the beach...this video helped save me $$$ though. bravo...

Brilliant, it worked. Thanks

Yep, it seemed to work for me too, thanks, well done.

it worked! amazing

Hey Joe, could you please tell how looks sensor position when you take off a sphere? I think something wrong with mine, when i took off sphere, that sensor looks not like right on center, it's a bit shift, that's why i think it works wrong with viewfinder when you are metering the reflected light

awesome post, it works.. wowww..... thank you!

Instant success! Tanks a lot.

Help....I purchased a old Minolta auto 4f meter....when I select non c and fire flash the non c flashes..even though I was holding correct button on meter..does this mean I have a bad meter? It works fine on ambient

wtf, this absolutely works. Thanks a lot!

Hi Does anyone know if it needs to be an America dollar note or would it work with other paper money?

Incredible!!! Thank´s!!!

how does that calibrate it by doing as in the video?

Worked for me, I was a stop over and now it is correct. I wish someone could explain how this works?

It worked! Thanks!

I am missing the flat and round dome for this, where can I get one?

and if you don’t have a dollar bill ? Do you have to put on the meter first?

amazing! works on a minolta auto meter iii. now i can use it with minolta booster ii. no dollar bill? use a white paper.

good news now mine works properly yay

Hello! I have a Minolta IV f that indicates ''U'' for low light no matter what ISO, speed or light condition it's pointed at. I've tried the dollar bill trick but it doesn't work. Any ideas how to fix that? A friend of mine told me that there are some buttons that you can click on to reset the lightmeter while opening it but he doesn't remember the sequence.. So if you have any ideas please share! Thanks!

No Joke!! It works

Open the head to find disconnected wire caused my too many head rotations. Don't suppose you have a video showing how to solder small wires? Not my forte, I end up melting everything!

I dropped my meter and opened the head try to fix it and found 3 different plastic "filter" or disc. One is clear, one is green and one is like a washer. Do I have to put them back in order? I did try without them and the reading is off 1 stop when I compared whith Minolta F spot meter. Can anyone help?

Yes, with the meter off. I truly do not know what takes place here, technically. It just works.

Hello! I have an issue with my Minolta IV F meter, Previously it used to show me the ISO in increments of 100,200,400,and so on, but recently when I took out my meter to use it after a long time, its suddenly showing me ISO in increments of 87,170,340 and so on, What could have gone wrong? Can anybody please help me to reset it back to normal ISO speeds. Thanks.

I don't think this is really a calibration. I have the problem where my Auto Meter IV F shows 3 stops off, and as far as I can tell, it's caused by the meter mis-recognising the incident metering dome as a reflective metering accessory. The operation you show in the video looks like it will clean or re-adjust the sensor that feels what metering accessory is attached.

all that matters... :D

Sorry for the quality. It still shows you what to do.

How does this calibrate the meter?

It doesn't. It cleans dirty contacts that are causing a bad reading.

I bought mine today, but found out it would show the "under exposed"-icon and a large E on the display, no matter how high or low I changed the values and settings. Does anyone know about this error?

​@@celonziajohnson Unfortunately I figured out that it is a technical error, which requires expensive repairs. I was able to return it to the second hand shop and replace it with a Kenko without paying extra, and it works great. But it is always a risk to buy second hand electronics, so in the future I will pay the extra buck and buy a a new light meter, with warranty and all. Probably Sekonic.

1. Learn what calibration really is. 2. Clean your sensor.

That could not possibly calibrate the meter. It will turn a non working meter into a working one, but not calibrated accurately. That would have to involve the sensor, not just the contact, which will get it closer.

I just (re)did this, and it works. I'm now going to do it before every major job/shoot, "just in case". Give it a shot and see if it works for you!

Plus, why would you ever trust doing this to a light meter when you go into a high end pro shoot?

Didn't work on mine. Still shows f22 when it should be 8.

Ok that's weird - thought what the heck - I'll try again - and it worked!!! What I did differently : 1st time - just used a piece of card and didn't rub. 2nd time : used a dollar bill (I'm in the Uk but had one) and did the rubbing thing.

That's not a calibration FFS!

Yea this is crap, I tired it and no luck
