Hi guys,
Extech makes a couple of very nice DC current clamp-on probes.
They have down to 1mA resolution, and one of them is very inexpensive
(around $140 if I remember correctly), and works as a standard multimeter as
well. Very rugged also.
Having a DC current clamp with 1mA resolution is very helpful in debugging
digital circuitry..
bye,

Tek current probes were a little less sensitive to heat but
just a warning to who may get a HP or Tek current probe the
ferrite is VERY VERY VERY fragile. Not only from shock but
watch out when you close the probe it chips easily
oh .. not sure about the HP but the cables on like the Tek
P6045 the cable to the probe has a lot of little wires in it
and does not like tight bends.
