1. A method of operating an electrochromic device comprising:
coupling a logic device to the electrochromic device;
applying a voltage to the electrochromic device;
bringing the electrochromic device to a base line condition prior to adjusting the frequency, wherein the baseline condition is a preselected tint state;
receiving a current from the electrochromic device in response to the provided voltage;
with the logic device, determining an exact operating condition of the electrochromic device from the received current, wherein the exact operating condition is an actual tint state; and
adjusting a frequency of voltage to the electrochromic device such that the actual tint state and the preselected tint state are the same.
