Voltage references have traditionally been very expensive, normally seen only in metrology labs. But this voltage reference provides good accuracy at a low enough price that students and hobbyists can afford a voltage reference for their own labs

I received my unit in 11 days and to my disappointment there was no calibration specs listed on the unit making it useless. I have contacted seller with this issue. I will update my review if I can get a unit sent to me with calibration specs. Very disappointed.

Nice little standard for the price. Now I have a reference for my Meters

I ordered one due to the size and price. I did not expect too much from it except to use as a quick check. I took it over to my HAM radio buddy who has an expensive 19999 count big name brand multimeter since this voltage standard did not come with the values filled in from the manufacturer. Here is what he found. 2.5v was 2.499, 5.0v was 5.002, 7.5v was 7.502 and 10v was 10.004. This is also what I had when checking on my Zotek ZT-5566SE 19999 count bench meter. So, my satisfaction is two fold. One, this voltage meter is accurate, highly portable and at a great price. And two, my Zotek (which I purchased here on Amazon) matches the high dollar meter. I will update with resistance numbers when I get them.Update: 3/22/2023I added an image of the readings from my buddies Fluke bench top multimeter. Once again matched my Zotek bench meter as well. Slight differences when using my Kaiweets ST600Y 6000 counts True-RMS multimeter. Not enough worry about for my uses.
