Special Test Charts

Most of the special test charts can be accessed on the Auto Phoroptor RS Controller
interface. Exceptions are Contrast Sensitivity, Suppression Testing, Crowding Bars,
and the Blank Screen. If these charts are displayed using the ClearChart 2 remote,
the window that displays the charts on the Auto Phoroptor RS controller LCD will be
blank.
The vertical and horizontal line chart on the Auto Phoroptor RS is used to bring
in the fixed cross cylinder lenses for near point testing and is not available on the
ClearChart 2. When that chart is selected, the ClearChart 2 will revert to the Dark
Screen with the ClearChart 2 logos.

Other Functions

Some functions of the ClearChart 2 are available
through the remote only: adjustment of the direction of
the astigmatic "T" and the lines on the Astigmatic Dial,
movement of the lines in the Horizontal and Vertical
Disparity test charts, and scrolling through the Educational
slides.
