Excellent choice... look after it and it will look after you. True RMS is useful too... enjoy

Just bought a new Fluke 179. Still, my Fluke 8000A is more accurate. I tested my Sound Technology ST 1701A with the 8000A and the ACV are spot on. THe 1701A is VERY accurate.
Following the manual of the 1701A and doing the '0 Meter Adjust' 150 mV, ect on the meter reads exactly 150 mV on the 8000A. 147.5 mV on the 179. I know in reality this is a non issue, but it's nice to be exact.

I'll try to get a hold of some 1% resistors and have a go at it.
Can't beat the Bench Top DMM.

Open it up and look at the board inside and google the board's model number. Fluke made some of the DMMs that Radio Shack [Canada] used to sell (though I seem to remember that being in the late 80s, early 90s).
