GENERAL OPERATING PROCEDURES
The operation of the SMART Colorimeter is controlled by a
microprocessor. The microprocessor is programmed with menu driven
software. A menu is simply a list of choices. This allows a selection of
various tasks for the colorimeter to perform, such as, scan blank, scan
sample, and edit test sequences. The keypad is used to make menu
selections which are viewed in the display. There are three operating
modes for the SMART Colorimeter – the TESTING mode, the EDIT
SEQUENCES mode, and the EDIT USER TESTS mode.

The Battery Disconnect Button
In most normal operations of the SMART Colorimeter the Battery
Disconnect Button should be in the “in position”. In this position, the
battery is electrically connected to the colorimeter. The battery can then
be used to power the colorimeter or it can be recharged with an external
power supply (see Battery Care page 45). Pushing the Battery Disconnect
Button to the “out position” electrically disconnects the battery from the
colorimeter and requires that an external power source be used to run the
colorimeter. (See POWER in the TROUBLESHOOTING GUIDE, page
48).
THE KEYPAD
The keypad has 6 membrane switches or buttons which are used to
perform specific tasks.
