Operating the 4x40
Optica
The parameters chosen during programming are displayed
numerically on the top three lines of the display. For programming,
see Chapter 5. A typical 4x40 display screen is shown below. The
system status is shown in the lower left, and the balance indicator is
shown in the lower right.
Figure 3-2: Typical 4x40 Display Screen
The balance indicator should show about five to seven blocks in
normal operation. If it shows fewer than four or more than eight, the
dew point sensor may need to have its optics signal level adjusted
(see Figure 3-3 below and
Balancing the Sensor Optics on page 7-2).

Network Operation
The VGA Optica can be operated and programmed remotely over a
network. Networked operation is very similar to operation using the
front panel. For programming from a network, see Chapter 6. A
typical network screen is shown in Figure 3-4 below.
