A red light glows on the instrument panel the instant you turn on the photometric range switch. This same switch also lets you select any one of five photometric ranges in transmittance or absorbance. Located directly above the range switch is the '"100% Adjust" control which sets the dial pointer to whatever reference value you wish.
