Help needed with calibrating my DIY Voltmeter

(1/1)

hillflyer:
Hello,
I have built a compact, portable 6 digit Voltmeter
using a LT2400 ADC and a Max6350 reference.
It has the input range of the LT2400, -0.1V to +5.1V.
Who in Germany could help me with getting the thing calibrated against their
own 'proper' DVM?

Kind regards,
Hannes

edit: the standard deviation value in the picture goes down to 2uV with shorted input

HighVoltage:
If you are in northern Germany, I can offer you a comparison to my many proper DMM, up to 7 1/2 digits.

e61_phil:
I'm also in northern germany (near Bremen). I have some calibration gear. A Fluke 5440B DC calibrator for example

@HighVoltage: Where do you come from?

hillflyer:
I am in the south, near Augsburg,
but I think I could package the little meter well and send it in the post.
Hannes

acbern:
I am very close to you...
And have calibrated standards.
Send me a PM.
