Default testing numerous AA batteries sitting around?

It lacks low AC volt scales and the plugs are not fully shrouded.

The transistor tester socket is a known hazard and I cannot see if battery
access requires the use of a tool, much safer if it does.

The battery test function is almost useless, 4mA load on a AAA or larger
cell tell you nothing - particularly if it is rechargeable.


The plugs are fully enclosed once they are plugged into the meter.


** Well yeah, but the shock hazard occurs when handling a plug - trying to put into the meter - when the tip end is attached to a source of high voltage.


To get
to the battery you have to remove 2 small screws and the whole back comes
off the meter.


** Excellent - batteries are shock hazards if they can become exposed by mere finger pressure or a bump.

The other common DMM hazard is having a non-fused high amps range - if connected across a source of high energy, the leads may explode. Such sources include car batteries and high current AC supplies.
