User Interface
The user interface for the Q45 Series instrument consists of a custom display and a membrane keypad. All
functions are accessed from this user interface (no internal jumpers, pots, etc.).
Keys
All user configuration occurs through the use of four membrane keys. These keys are used as follows:
MENU/ESC
To scroll through the menu section headers or to escape from anywhere in software. The
escape sequence allows the user to back out of any changes in a logical manner. Using
the escape key aborts all changes to the current screen and backs the user out one level
in the software tree. The manual will refer to this key as either MENU or ESC, depending
upon its particular function. In the battery-powered version of the Q45, this is also the
ON button.
UP (arrow)
To scroll through individual list or display items and to change number values.
LEFT (arrow)
To move the cursor from right to left during changes to a number value.
ENTER
To select a menu section or list item for change and to store any change.
