VoltageStandard.com - Low cost Voltage References

how much did you pay for the postage?

I have a order from 2014 where I paid $30 in shipping for two standards.

these look really handy for those w/o access to precision references. voltagestandard.com



the dmm check is only $32.50 with free re-calibration for a year and only $5 including return shipping after that. similarly low calibration deal for the other 2 models!

anyone here use one of these?

I use DMMCheckPlus, for a couple of years now I am very pleased with it.  The plus version has a little extra over the non-plus.  You can check the website for the difference.

Service was great.  I ordered my DmmCheckPlus with the wrong frequency AC, the Plus can give two different AC frequencies and I mis-entered one of them.  I contacted them, shipped it back and they re-calibrated it to what I need without charge (I paid shipping for him to return it to me after re-calibration.  It was my fault so it was fair that I paid the (re) shipping).

If I recall correctly, the DmmCheck/Plus are tested using an 8 digit HP dmm for accuracy.  I have high confidence with it.

ps: adding this:

While the DMMCheckPlus has a single 5V reference, but it also has a built in set of reference resistors known to 4 or 5 digits.  They are soldered in series - in other words, a voltage divider.  I use that to divide down the 5 volt and do sanity check on the lower ranges down to mV.

how much did you pay for the postage?

I paid ~$18 for shipping of single item with a box. Device (DMMCheck plus) is still going strong for ~1.5 years so far.
If you consider getting one of these, I strongly recommend adding a plastic box/case as well.
