Voltage follower A2 buffers output that can be adjusted over full range from 0 V to zener limit with R4. Positive supply of A2 must go to voltage slightly more positive than +3 V common if linear output operation is required over full range.-W. G. Jung, IC Op-Amp Cookbook, Howard W. Sams, Indianapolis, IN, 1974, p 159-160.
