I've let the 3245A run for a few days now to stabilise in a temperature controlled room (~25-25.5C, 35-45%RH) and today took some quick measurements with my old 34401A - I had the 10V range "calibrated" a few months back using a friend's DMM7510.
I didn't get any paperwork with the 3245A but there's a calibration reference sticker inside, not sure if I can get anything from Keysight based on that.
I fixed the range to 10V in the 3245A to prevent it auto ranging, the readings look reasonably close to spec. Looks like a sweet spot between 2 and 4V, where the disagreement is lower which is a tad interesting.
I'm looking to get this and one of my relatively stable (less drifty) 34401A re-calibrated at the local Keysight service center down the road, not looking forward to the $$$ quote though ... anyone have experience dealing with their calibration services in Melbourne directly ?
