On the AC Volts range with the probes shorted together the meter reads 0.022 VAC when ideally it should read 0.00 VAC.
That seems high. My ancient Fluke 87 shows 1-2 mV with the leads shorted. And, that's to be expected with wire leads - they'll pick up whatever random RF is floating around. To get closer requires a "relative" measurement function, which puts you into the 87V/287 ($400-600) range.
To the OP:
The Harbor Freight ones aren't bad for what they cost (!), and are handy for basic wiring needs - if you break one, go get another. But IMO, if you want a reliable meter you can trust to be accurate and which will last, look to Fluke or HP/Agilent/Keysight. You can get a
Fluke 106 for <$100, and a
113 for not much more (113 doesn't do amps).
Depends on how you are about tools. Do you buy hammers from the $1 bin, or do you buy an Estwing?
