44C2 5V meter will not read over 4.5V

by romney on Mon Nov 29, 2021 5:53 pm

I bought 2, ELECALL 44C2 meters. One works fine. The other one will not read full range. It stops at a bout 4.5V. The bottom of the range (0V input) is about 0.3V. So I cannot adjust it to read the full range as it is already past the zero in the low end. I verified it is the meter by swapping meters in my circuit, and the problem follows the bad meter. The good meter reads correctly regardless of which circuit it is in.

I just bought these about 2 weeks ago, but sadly do not have the receipt. Can I exchange this meter, or do I have to buy another one?

Yeah, we can do a replacement. The comparison test is good diagnostic evidence, and you’re well with our 30-day return/replace period.

This will sound like a complaint, and I guess it is a little. It took so long to get a reply that I gave up and printed a special meter face so I could use the meter with the offset voltage range. I think at this point I will keep it.

You're still welcome to a replacement, even if you found another solution. You can use the new one for some other project.

Thanks for your help. A new meter is being shipped to me. The old one still seems to have more problems, so I need the new one. Again, thanks for the help.
