VoltageStandard Vref5-002 - 0.002% Precision 5V Voltage Reference

[@mjlorton]

No, not for most general electronics, but it is something I enjoy playing with.

[@DaveMcAnulty]

For anyone interested, the enclosure of the voltage reference appears to be a Hammond Manufacturing, 1455 Series extruded aluminum enclosure. I own 3 of these enclosures in various sizes and end cap configs (plastic vs aluminum) and I they are as nice in person as in the video.

sir i have searched many video's on youtube which are a big time waste...hopeless....he is an expert above.......i am his big follower........hence I wanted a video from him........

[@mjlorton]

Thanks. I reviewed it in T4D#68.

[@birrbert]

Nice vid with nice postcards! I immediately spotted mine. :-)

[@electrotools8083]

Hi, great video!, What is the model and brand of red high presicion DMM multimeter? (the red one)

[@mjlorton]

Thanks Ed...have a look at T4D# 65 & 66 I have written a short bio / intro to myself on my forum under General then " Introduce yourself topic!" ...it should explain a bit...

[@PuchMaxi]

Mine has also arrived! Very nice ;-)

Hey Martin how is the "building the power supply" project going? Are you still gonna continue with that?

[@jamjamamam4139]

i see Ikskile standard in backround. have you visited Latvia?

[@sampandolfyM2]

You could not have seen a video like this already on eevblog because mjlorton is reviewing a new product that eevblog has not reviewed yet.

[@eddraper]

Well done and interesting... I missed your moved from South Africa. Do you have a video explaining the move? It would also be interesting to know what occupation you elected to go into rather than EE. I know... I'm a nosy, presumptuous S.O.B. ;-)

[@NavStuff]

I like the non-shaved look...

[@seyedmarashi]

martin, can i know this red multimeter brand name? how much is?

[@Chen-zd6rx]

how to diy the 0.002% voltage reference ? I am very interested

[@Yuēhàn24]

what equipment needs it's supply voltage to be within 0.0025% to operate correctly?

[@ajhiggins1]

Think I seen a video like this already on eevblog ?

[@rushikeshk25]

PLEASE HELP SIR.........and can u please make video on the use (and not the working)..........of the capacitor, transistor, and wireless circuits...............if not possible atleast try to do 1 video on any 1 part mentioned above form the 3..........please

[@snipersquad100]

I could do with one of them, wanna see how good a £5 multimeter is lol

[@davidjereb]

7:20 NO! That's NOT how multi-slope ADCs work!

[@ElGatoLoco698]

I'm curious. How much money do you think you have in equipment in your lab? I bet you got more equipment than many labs.

Hi Martin, What is the accuracy over load? I have been messing around with a MAX6325 using a MAX5481 1024 Digi Pot to trim it down. with NO Load I am able to trim it to 2.500 006. But when I hook up the out put to a DAC1220 DAC the reading ~ is 2.500 050 Im trying to see if this is within spec of the part. Here is my project : docs.google.com/document/d/1I-DNk5t_UDZP3AKksd_8cP-8Bp4GIJf8T8ZfADh2-2o/edit?usp=sharing mike

What's the model of the multimeter shown at 11:59? I believe he says 'Amprobe M168' (or maybe AM-168), but I can't find any multimeter by this name. Does anyone know?

[@wesleyxu8849]

Maybe it's Amprobe AM-160-A

[@camurgo]

@@wesleyxu8849 I think you are correct, thanks!
