Despite that "too many already" admission, I couldn't resist ordering that
meter, whose price has now gone from $15.72 to $25.72. Here's the Review I
just posted to Amazon:
=======================================
Well, that didn't turn out well: I bought the meter on 6 Jan 2018 and
didn't get around to using it until last night, 2 Mar. I used it because
the heat pump quit after dark so I need the illuminated display.
Unfortunately, that turns itself off after 15 seconds -- not long enough
for my old self to do anything useful. Using a mouth-held flashlight, I
measured about 12 volts on all 3 phases of the power to the HVAC, so called
the power company. Imagine my MSEE embarrassment when their meter showed
120 volts at those 3 points! The heat pump had an internal failure, not
power loss. Today I've tested and found that on all ac and DC ranges, the
reading is only 1/10 what it should be -- the decimal is misplaced. The
only other range I tested is *C/*F -- that's at least 10*F low. The real
disappointment is that my Amazon return period expired on 7 Feb.
=======================================
So, if you've bought one, or plan to, be sure to check it ASAP after it
arrives.
If I can't get warranty support for it, I'll stick a warning label on it
and probably never read that again.
Certainly not my most expensive folly.
