Re: [volt-nuts] Would you be concerned if the manufacturer does not have an uncertainty budget, so can't provide uncertainties in a calibration?

understand, it is maybe different here in Germany then, there are a number of labs with pretty low uncertainties who also support old gear adjustments. on the other hand, you have to know who you are working with for what gear. Otherwise you can have unpleasant surprises. in your case, if you

I have an HP 4339B high resistance meter. It can read up to 1.6 x 10^16 ohms, with a basic uncertainty of 0.6%. It has a built in voltage source of up to 1 kV. I've contacted Keysight (UK) and asked for calibration cost, with uncertainties, for this 4339B. However, they have said they can't
