state.
•

key is intended to select and indicate choices for the various
instrument functions.
•
The gray arrow

and

arrow keys are used mainly to scan through menu
choices and, in conjunction with the square

The liquid crystal display has two rows of sixteen characters each. It is the primary means
to communicate menu choices and answers. Measurement information, menu selections,
sample names or codes, and instrument status are all indicated on the display.
