Part 6 – Configuration
6.1 User Interface
The user interface for the DOTX-45 instrument consists of a custom display and
a membrane keypad. All functions are accessed from this user interface (no
internal jumpers, pots, etc.).
When power is first applied, you may notice that the display does not come on
immediately. This is normal. There is a 5 second start routine that runs before
the display illuminates. In addition, you will notice an occasional “flicker” of the
display, occurring about twice an hour. This is the result of a display processor
refresh program that insures long-term display integrity, and will always occur
during normal operation of the instrument.
