Push Buttons; Operating State - Teledyne 8800T Instruction Manual

3.4.3 Push Buttons

Three push buttons are located on the front panel.
Each button is marked with an icon engraved above it.
In general the MODE button navigates through the different
user options "Modes"; the UP and DOWN buttons modify
the units, values or choices in the selected mode. Refer to
the flow diagrams in Appendix A for detailed overview of
button functionality. A button may be held down for a pro-
longed time, for accelerated incrementing or decrementing
of numeric values.

3.4.4 Operating State

Upon power up, the unit performs certain initialization tests
(see table in section 3.5), and enters the 'Operating State', in
the Viewing Dewpoint mode. Depressing the 'MODE' but-
ton will change modes (see appendix A) in the following
order: Viewing Dewpoint ‹
Start Calibration ‹
Viewing Dewpoint. The unit will return to Viewing Dew-
point mode if no buttons are pressed for 30 seconds, unless
it is performing a calibration.
