How to Program New Parameter Settings
The PARAMETER Screen shown in Figure 3 on page 15 is used to change
the Pulse Generator’s parameter settings. Table 2 shows the range of
possible settings for all parameters.
Table 2.
Programmable Parameters for the Pulse
Generator
To change a parameter setting, follow these steps from the PARAMETER
Screen (Figure 3 on page 15):
1. Tap the
New
button for the parameter you want to change. A pop-up
menu displays the range of possible values, with the current value
setting appearing in boldface type (see Figure 10). If there are values
greater than or less than those shown on the screen you can view them
by tapping the appropriate set of the double arrows. Look at the left
half of the screen and note that the parameter for which the value is
being changed is enabled (clearly visible) and the other parameters are
disabled (“grayed-out”). In the example in Figure 10,
Output Current
is enabled and the other parameters are disabled. The value of 1.00 mA
has been selected for the
Output Current
parameter.
