If excessive drive is applied, irregular oscillation or quartz element fractures may occur. To determine frequency stability, use parabolic curvature. For example: What is the stability at 45˚C? 1) Change in T (˚C) = 45 -25 = 20˚C 2 2) Change in frequency = -0.04 PPM x (∆T) 2 = -0.04 PPM x (20) = -16.0 PPM #4 #1 #3 #2 1.5 #4 #1 #3 #2 Figure 3) ECX-205 Pin Connection- Top view Figure 4) ECX-206 Pin Connection - Top view ECS, INC.
