...
Could you calibrate a Solarton 7081 DVM, a Transcell II 10.0000V reference, and a Dekapot Kelvin Varley divider?
As noted in the first post, we will bring a Fluke 5700, a HP3458 op 002, and a KS E4980A ... maybe that will be assisted by a Fluke 8508A, a 732A and a 752A , a 200g balance,... maybe ..
a lot of silverware ... sometimes even gold-nuggets.
All that gear always stay overnight at the PTB in Braunschweig, is transported to the fair early in the morning, build-up, warm-up, cross-checked, 10 o'clock: the crowd is coming, 8h for about 60 calibrations ,back to BS.
All our gear is freshly calibrated, but again:
DON'T EXPECT THE LAST PPMs AT THE FAIR ! It's not in the lab.
(Reminds me to pass the 5700 over my fellows, to the 'german volt lab'

Working horse is the 5700, about 96% of the devices are handheld DMM. You declare one (of up to 7) calibration point (U/I DC/AC Hz), we operate the 5700 (still standby) and hand you a cable with up to 5 connectors, you operate your device, you say OK, we set the 5700 in operation mode. You note the result.
Voltage references, reference impedances ... as long as the 3458 or the E4980 (and maybe, I currently can't say for shure, we are working on it, a 8508) can measure it.
A KVD is a different thing, and usually much more time consuming, unless you say , hook it up to the 5700 (or your Vref) and dial out 7 (+x

) points measured by our DMM.
For meters that deserve it, we have sockets for warm-up, invest some more work. We had some 6.5 up to 8.5 digit gear in the past

I'm happy that my former fellow Roland will join us again, he's retired (... or so), has more than 40 years of experience in E calibration, but even he don't know all justification procedures by hart, so look up your cal procedure, pack the important pages of the SM, make a plan , make a plan B

... and be there early!
Yes, usually we bring some other 'naked' gear ... metrology porno
