I have seen meters like these a few times. Usually when someone tries to measure how
many "amps" there are left in their car battery
.
I work in a small electronics shop, so I do sell meters. The fact is: People, even the pro's, are
not willing to spend more then 40.00 EUR on a meter.
The cheapest meter for 9.90 EUR is the one I sell most. That thing is utter rubbish.
I have some nice meters in my cabinet, but they cost 80-100.00EUR and no one is prepared to spend
that much money on a multimeter. Sad, but true.
The 40.00 EUR meter has some nice features but is still shite. That's what my boss gives me to work with.
Usually that's OK, because we don't do repair work, I only need it to check wall warts, batteries and fuses.
Recently I accidently had the leads plugged into the Cx/Rx sockets and wanted to measure 230V on the primary of a transformer... BANG! SPARK! SMOKE! That made me jump, I can tell you. Luckily I didn't hold
the meter in my hands.
