No no no, I've already found that this green box is for the wires. There is nothing wrong with anything else.
I was only trying to figure out wiring on it.
The 2 blue trimpot potentiometers are the calibration points and they're fine :]
Very good points. this meter has a Barons 3296 square trimpot potentiometer. Its sealed meaning its almost solid state even though it has moving screws. It has 2 of these potentiometers. one sets the voltage at 10v within 0.01% accuracy. The other tops it at 15v, same deal. its a small scale but...
OK im logging notes on this. My voltmeter is crucial. Its monitoring a battery bank RV set up. I already tried a SMD VM-1 analog LED voltmeter due to all the hype around it. I tested it against a cheap 2.5 class voltmeter, a $100 clamp meter an a $50 digital voltmeter on my batteries. They all...
Yep, mine looks almost exactly like that only the screws have blue hardened epoxy glue or locktite on half of it. Same brass screws. Now i know not to touch that area. Thank you for all the valuable info.
Wow that is nuts! I also touch the back of the curicut board and the needle instantly falls back to zero!
So glad you told me this. this would've drove me mad had I not known. So this illustrates the importance of these 0.5 class voltmeters needing to be installed rather than handled. Slightest...
Thanks for this! Thats genius. This turned out to be the issue. The voltmeter was on my comforter on my bed developing static. I verified this by running finger over the cover and the super fine needle dropped! holy cow.
Yes, in this case I think he assumed I turned the glued in place micro flat head screws.
Heres something really funny though. I understand now these screws on the green box are just back off and back on tension for the + an - connections or "sense" wires. However when the dial is perfectly...
I guess this was a misunderstanding. The seller assumed I turned the blue terminals on top. So I guess its still in calibration. The BLUE set screws that are glued in place are the calibration screws.
Oh well this can help others hopefully.
The seller on ebay for this Zantum Model ZAPV15B class 0.5 just told me the blue is the wire terminals. Is this correct? I think maybe he thought I was talking about the blue screws that are set in locktite that you see sticking out the top.
Yes these 2 screws on this green thing. Now I'm being told they ARE negative and positive terminals. This, after I was told they were calibration screws but I think they mistook thinking I meant the blue locktite set screws on top in the photo here I'm uploading.
EDIT: I can't seem to upload new...
How did you find PF?: I have been trying desperately to correct a mistake I made when I received my new Zantum Class 0.5 10-15v voltmeter. The 2 screws on the back I thought were for wiring. Sure enough I found out they were calibration screws. I willy nilly began turning them thinking "is this...
