- Start with the test plate switch at OFF.
- Turn the control knob (potentiometer) on, and to near
maximum. - Touch each plate with the probe, while holding the copper
pipe with one hand. Only the left plate should give you a
sound from the speaker. Turn the test plate switch ON.
Now both plates should give you a sound when the probe
touches them. - Turn the test plate switch OFF again.
- Pick up the handhold, squeeze it free of excess water.
- Pick up the probe in the same hand, holding it like a pen,
between thumb and forefinger.
Dampen your other hand by making a fist and dunking your
knuckles into the wet paper towel in the saucer. You will be
using the area on top of the first knuckle of the middle finger or
forefinger to learn the technique. Become proficient with both.
Immediately after dunking your knuckles dry them on a paper
towel folded in quarters and placed beside the saucer. The de-
gree of dampness of your skin affects the resistance in the circuit
and is a very important variable that you must learn to keep
constant. Make your probe as soon as your knuckles have been
dried (within two seconds) since they begin to air dry further
immediately.
With the handhold and probe both in one hand press the
probe against the knuckle of the other hand, keeping the knuckles
bent. Press lightly at first, then harder, taking one half second.
Repeat a half second later, with the second half of the probe at
the same location. There is an additive effect and you get two
chances to listen to the current. All of this takes less than two
seconds. Don't linger because your body will change and your
next probe will be affected.
