Button Description
The VIEW key is used to review alterable parameters currently in use. It has no effect on the
program being executed at the time. Once pressed, the user is prompted for a FUNCTION to be
viewed. The parameters visible under the function can be stepped through using the ENTER key.
The SET key is used to change program settings or the entire sampling program. Changes made
have no effect on the program being executed at the time until the RESTART key is pressed twice.
To leave a programming sequence before entering it in memory either press SET or VIEW and the
sequence is aborted.
The ENTER key is used to complete either a VIEW or SET sequence, where sub-menu items are
available. Under the control of the VIEW key, parameters are scrolled onto the display, changing
with each use of the ENTER key until a complete display of the parameter is completed. Under the
control of the SET key, parameters can be displayed, with the added ability to change their values,
using the ENTER key to accept the new value until the entire parameter is displayed. (Note: New
values are not operational at this time.)
