Board P10137-1

Note: R30 is 102 Ohms in most units, though in some

cases a different value may be used to match the

installed S100/S200 LM334 (C5826-0) device grade.

This is the standard value and is used with the most

common LM334 grade, green. If the LM334 is marked

with a blue dot, R30 should be a 107 Ohm resistor

(A10265-10701); if it is marked with a yellow dot then

R30 should be a 100 Ohm resistor (A10265-10001).
