The parameters chosen during programming are displayed
numerically in the top half of the screen, and graphically at the
bottom (see Figure 3-1 below). To program the unit, see Chapter 4.
A balance indicator is shown as a vertical bar on the right side of the
screen. It shows the state of the feedback control loop controlling the
mirror temperature. When the system reaches steady-state (the
Control status indicator is displayed), the balance indicator should be
near the center of its range. If the balance indicator is near the top or
bottom of its range, the dew point sensor may need to have its optics
signal level adjusted (see Balancing the Sensor Optics on page 7-2).
