Not to confuse the issue, but, actually your meter on the 2 volt scale
with the 1000 ohm resistor gives a reading which is equivalent to the
current in milliamps, not microamps. You read .436 (volts) which is
equivalent to a current of .436 milliamps, which, if we then move the
decimal place in our head, is 436 microamps...
The direct reading is equivalent to the current in milliamps.

Hi Wayne,
Thank you for the kind words.
The meter in the pictures is a real cheapo. Here is the URL:

<http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=98025>
These have a DC current range, but I decided not to use it in
the instructions. I find that having a Multimeter left on the current
range will invariably lead to a person blowing a fuse , which, in the
ELcheapos, would be impossible to find. And I suspect that this does not
bother the manufacturers, as they end up selling more of the them.
Instead, I use a one K resistor and the two volt range of DC voltage
measurement. The resulting reading we'll be in microamps.
Best regards,
Arnold

Some people tell me, I have lost my mind. I tell them,
Get the Chess Board, and sit down on the other side.
Maybe I can find it, ....... worry about yours.
