User Interface
The user interface for the Q46 Series 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.
