INSTRUCTION : To set the ct ratio press and hold the button, ctr will display in first window and previous setting of ct ratio in second window. Now keep pressing the button the ct ratio will start increasing by steps of 5 amps, momentary releasing and then again pressing the button the ct ratio will start decreasing in steps 5 amps. In k. Amp range the increasing and decreasing steps are 50 amps. Releasing the button at desired ct ratio will be stored.
