I needed a new DMM anyway, so I ordered the talking one from the
NFB’s Independence Market. It comes with pretty scant printed
documentation (a single sheet) in very small print Engrish, marking
the product as most definitely made in China. The specs tell me it
is quite adequate to the task I bought it for, but I’m a wondering
about the test leads.
They aren’t using standard banana plugs, which makes sense given the
talk button and LED in each probe. But the connector looks like it
will still accept a standard banana plug. Looks can be deceiving
though (yes, it’s true even if you’re blind!) and I’d rather not cook
my new meter just yet! *grin*
Clearly the LED pins can be at least shorted, since the talk button
does exactly that. But a normal banana plug might or might not short
them to the test lead as well.
Has anybody let out the magic smoke doing it? *grin*
