on DC milli-amps (@1.0mA), it is 2 counts higher than my 34401 . Resistance, 600ohm range (100ohms) it's 3 counts higher, and the 6k, 60k and 600k ranges (using 1K, 10K, and 100K resistors), the EEVBlog meter is within 1 count of the calibrated 34401.
For AC volts (5V AC, square wave @ 100hz), it is 24 counts lower than my 34401.
Pretty much spot on -- I don't think it could be any closer.
I'm very happy with my purchase.
