2.  InfiniiMax III Probe Heads

N2836A InfiniiMax III Solder-in Probe Head

Figure 33

Trimming axial resistor leads

The lead to be attached to tip pc board will have a 90 degree bend to 

go into through hole in the tip pc board.

The orientation of the lead is not important.

Figure 34

Bending axial resistor leads

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.
