Operation Using the SRI (RGB 118 PLUS only) The SRI feature of the RGB 118 PLUS is used to determine the approximate horizontal and vertical scan frequencies of video and computer monitors. To use the SRI, hold the RGB 118 PLUS with the feet against the face of the monitor and near the center of the screen as shown in Figures 1 and 2 below. To view the vertical scan frequency, hold the unit so the LCD readout is on a vertical plane (red SRI button is in the uppermost position) as shown in Figure
