After letting the meter sit at room temp after shipping (winter is setting in), I checked it for calibration. For the most part, seems alright but the DC voltage is out more than I would have expected.
At 10V 17B+ reads 9.95, or -50mV error
At 1V, 17B+ reads 0.994, or -6mV error
The specs state +/-0.5% of reading + 3 counts. On the 40V scale, the res is 10mV. So if I am reading it right, a 10V signal could be off by +80/-20mV. On the 4V scale, it's 1mV res, or +8/-2mV.
Maybe I am not reading the spec right, or my math is wrong. Seems like this meter is out on DC volts. The rest of it looks good. Maybe one of their DC calibration standards is off where the meters are being aligned.
My reference was last checked for cal last summer.
Someone had posted that the 17B and 17B+ were the same board. This is not the case at all. The 17B+ is aligned digitally, not with pots.
I would expect most of the higher end meters are aligned this way today. I wonder with these meters, does Fluke make the tools available to align them?
At a glance, the layout looks alright. All the basic parts in place you would expect. They used a lot of grease on this one. It was coming out of the vias and the center shaft of the rotary switch has so much it covers the back case half.
Here are a few pictures of the 17B+ PCB and what I am calling excessive grease, along with a picture of my Fluke reference standard and HP34401 (both in cal)...
