Re: Is my DMM broken (cannot read current)?


<mrdarrett@xxxxxxxxx>

How much trouble could it have been for the manufacturers to add a 10A
fuse to the 10A input...?


** A fair bit, actually.


I guess that's what the home circuit breakers are for...


** No way on earth.

Simple, cheap DMMs ( ie intended for hobbyists ) are not safe to use on AC
mains wiring.

They should *never* be used by an electrician - for example.

Only DMMs which carry a safety category rating are safe to use around high
voltage and high energy circuits like the AC supply.

They all have things like shrouded plugs on the leads, fused high current
ranges ( using special fuses that cost more than a cheap DMM) and no access
to the battery compartment without a tool.
