Bought these two LED voltmeters from different vendors at different times. Total cost was about ยฃ11. Both meters have 5 digits with 3 decimal places of accuracy. They cover an excellent voltage range 0-30v so my area of interest around 12 volts is slap bang in the middle. Very surprised with their correlation. Barely a digit of difference between them.
Anybody care to share with me a link or search method?
I was about to order a few of these units for a diy bench psu. Is there a way to add an adjustment pot that you can easily get to?
They may use an Internal precision Voltage reference ๐
Buen video
Sir, i've ordered different panel meters from China, i still waiting for them to be shipped.
And yes, i am also surprised how precise are. China manufacturers produce more accurate instruments than ever.
I admire your interest in electronics, and appreciate your willingness to share your experiments and their results. Thanks.
I'm pretty sure I've seen 4 decimal place LED voltmeters on eBay recently, but they may have been 4DP up to 3 or 4 volts and 3DP beyond. May be useful if you're measuring low voltages.
Hi – don't worry – I've found them. My eBay search mojo went walkabout for a while there… ๐
Hi, nice video. I can't seem to find these voltmeters on eBay. Would appreciate it if you could message me the link for them.
