Install the power cord as shown in Figure 9. Pull
the power cord wires apart about 2 inches on
one end. Strip the insulation off of both wires to
expose 1/4” of bare wire. Note that one wire is
ribbed on the edge. Solder the red alligator clip
to the ribbed wire. Solder the black clip to the
smooth wire. On the other side of the power
cord, pull the wires apart 1/2”.
Strip 1/4” of
insulation off of both wires. Make a knot to serve
as a strain relief (about 1 inch from the end).
Solder the ribbed wire to the hole marked “+” and
the smooth wire to the hole marked “–”.
Install the pulser tip as shown in Figure 10.
Using the 1 1/2” wire, strip 1/4” of insulation off of
both ends. Solder one end to point P on the PC
board. Solder the other end of the wire to the
pulser tip groove.
Punch out the five holes in the front label. Peel
the backing off the front and back labels and
stick them to the case as shown in Figure 11.
The front label should be placed toward the back
of the indent (toward the 3 pins) so that the LED
and switch holes align with the case holes.
Insert the 3 pins P1, P2, and P3 into their holes in
the front label. Insert the PC board into the case
so that the LED and switch protrude through the
label (see Figure 11). Insert the 3 pins into the
PC board and solder (see Figure 4).
Place the unit into the case bottom and fasten
with two #4 screws. Do not over-tighten or the
holes may strip out.
Cut a 13/16” piece of red shrink tubing and slide
it over the pulser tip until it touches the plastic
case. Shrink the tubing by heating it with your
soldering iron. Be sure the soldering iron does
not contact the tubing or plastic case.
This completes the assembly procedure. Your Logic
Probe is now ready for testing.
