HOW TO TEST YOURSELF
Best:
Use a large plastic project box instead of the shoe box. Do
not use project boxes with metal lids. If you can not find all
plastic boxes, remove the metal top and mount the test plates to
the bottom. Use insulating sleeves and solder all connections.
Probe And Handhold
These are what you grasp when testing. The places to attach
the probe and handhold are described with the circuit instruc-
tions.
Acceptable
For the probe use
an empty ball point
pen (no ink) with a
metal collar by the
point. Connect a two
or three foot alligator
clip test lead to this
collar. For the hand-
hold use a cheap metal
can opener (the kind
that fills your hand)
with a second alligator
clip test lead attached.
Best
The Archer Precision Mini-Hook Test Lead Set has a ba-
nana plug for the probe on one end and a mini-hook on the
other end for easy attachment to the circuit. Tape a long, new
pencil to the probe; this makes it easier to hold. The best hand-
hold is simply a 4 inch piece of ¾ inch copper pipe (which a
hardware store could just saw off for you) connected to the cir-
cuit with a three foot alligator clip test lead.
