Yeah, but how many of these counts will actually be valid without a special setup? Resolution != precision. But having said that, yeah, the MH 30M is both more accurate and has a higher resoltion than the Energy.
But, OP was considering the 50,000 count Fluke 289, so the MH Energy might fit his needs. And having a single multimeter that measures both voltage and current will save a lot of time and hassle. Here's some other features for comparison:
The MH Energy has a 10 times larger log memory (300,000 vs. 30,000 values). The actual memory is 16 times as large (2048K vs. 128K).
The MH Energy has an RTC for time stamping log values, the MH 30M doesn't.
The MH Energy has a fast continuity buzzer (50ms), the MH 30M doesn't.
The MH Energy has a faster data interface (38400 baud vs. 9600).
The MH Energy has a backlight, the MH 30M doesn't.
The MH Energy can be fully remote controlled from the PC, without changing jacks or operating the rotary switch, the MH30M can't.
Both cost about the same. But IMHO, the ability to not just measure DC power, but also true, apparent and reactive power is a killer feature that will make the Energy infinitely more useful in day to day use.
It's actually ridiculous that there are virtually no multimeters out there that can measure voltage and current simultaneously. What's up with that?
