once the processor is installed, it is CRITICAL that you make SURE that they are installed
correctly and that there are no solder bridges.
__ Locate the 2.2K resistor just to the left of the optoisolators (it will be marked “222”).
Remove ONE 2.2K resistor (marked “222”) from the tape and solder it in place. Inspect the
solder joints with a 10x jeweler’s loupe to make sure you don’t have any solder briges.
__ Locate the 2.2K resistor just to the left of the resistor you just installed (it will be
marked “222”). Remove ONE 2.2K resistor (marked “222”) from the tape and solder it in
place. Inspect the solder joints with a 10x jeweler’s loupe to make sure you don’t have any
solder briges.
__ Locate the 10K resistor just to the left of the resistor you just installed (it will be
marked “103”). Remove ONE 10K resistor (marked “103”) from the tape and solder it in
place. Inspect the solder joints with a 10x jeweler’s loupe to make sure you don’t have any
solder briges.
__ Locate the 10K resistor just to the left of the resistor you just installed (it will be
marked “103”). Remove ONE 10K resistor (marked “103”) from the tape and solder it in
place. Inspect the solder joints with a 10x jeweler’s loupe to make sure you don’t have any
solder briges.
__ Locate the .1 uF capacitor just to the left of the resistor you just soldered, it will be
marked .1 uF. Remove ONE .1 uF capacitor from the tape (it will be brown), and solder it in
place. Inspect the solder joints with a 10x jeweler’s loupe to make sure you don’t have any
solder bridges.
__ Locate the 10K resistor just below the capacitor that you just installed (it will be
marked “103”). Remove ONE 10K resistor (marked “103”) from the tape and solder it in
place. Inspect the solder joints with a 10x jeweler’s loupe to make sure you don’t have any
solder briges.
__ Moving to the left, locate the 1K resistor next to the .1uF capacitor that you installed a
few steps ago. Remove ONE 1K resistor (marked “102”) from the tape and solder it in place.
Inspect the solder joints with a 10x jeweler’s loupe to make sure you don’t have any solder
briges.
__ Moving to the left, locate the 10K resistor next to the “notch” that’s marked on the
board (it will be marked “103”). Remove ONE 10K resistor (marked “103”) from the tape and
solder it in place. Inspect the solder joints with a 10x jeweler’s loupe to make sure you don’t
have any solder briges.
__ Locate the .1 uF capacitor just to the left of the pressure sensor (the small silver part
with a hole in it), it will be marked .1 uF. Remove ONE .1 uF capacitor from the tape (it will
be brown), and solder it in place. Inspect the solder joints with a 10x jeweler’s loupe to make
sure you don’t have any solder bridges.
