Maintaining Probe Heads
3
Use the soldering iron and solder to fill the holes in preparation for mounting the new
resistors (or wires).
4
Use the flux pencil to coat the solder joint area with flux.
5
Locate the trim gauge which is supplied with the N2836-68701 replacement axial resistor
kit.
a
Place a resistor over the lead length gauge shown in
. Trim the
leads to match the drawing. The orientation of the lead is not important.
b
Place a resistor over the bend gauge and bend the leads to match the
drawing. This bend fits in the hole in the tip’s PC board.
Figure 51
Trim Guage
6
Holding the resistor lead or wire in one hand and soldering iron in the other, position the
end of the resistor lead (after the 90 degree bend) over the solder filled hole.

Soldering in a new axial resistor
7
Touch the soldering iron to the side of the hole. When the solder in the hole melts, the
resistor lead will fall into the hole.
8
Using a digital volt meter, measure the resistance from the coax center conductor to the
resistor tip. The DC resistance should measure 450 ohms.
CAUTION
Do not leave the iron in contact with the tip any longer than necessary.
CAUTION
Remove the soldering iron as soon as the lead falls into the hole.
NOTE
Because the thermal mass of the joint is very small, extra dwell time with the soldering iron is not
needed to ensure a good joint.
