Saving Changes and Exiting the Input Selections Menu. Soft keys to exit the Input
Selection menu are located at the bottom of the screen. When you touch the Accept
Changes soft key, any selections made are entered. If you touch the Cancel soft key,
all changes are deleted before returning to the current application. Pressing the Clear
Menu button also exits back to the application.
The Calibrate menu provides a soft key to start calibration. Calibration of the analog
acquisition system is done after touching the Calibrate Now soft key. Offset changes
that occur with temperature will be removed. If operating the AM700 in conditions
that permit large ambient temperature changes, a calibration of the analog system
improves the accuracy of the measurements. If ambient temperatures are stable, a
calibration done infrequently is adequate to compensate for component aging. A
calibration should be done at the ambient operating temperature to produce the best
accuracy.
