7.0 Instrument Configuration (CONFIG mode)
The instrument has been designed to provide the ability to customize the instrument
according to needs at any time during normal operation. This mode has been split into
sub-menus to facilitate instrument configuration. This section describes how to use each

instrument has a time-out feature that automatically returns the system operation to the
AUTO mode after a fifteen (15) minute period.
