CALIB.EXE is the DOS Pen Calibration utility.  It performs calibration of the

pen interface for the 6100 Computer, as well as other PEN*KEY computers.
Calibration is simply the alignment of the location of the cursor to the same locaĆ

tion where a finger or pen is placed on the touch screen.  The 6100 Computer

comes with default settings that are normally acceptable for most applications.

However, some applications, such as signature capturing, may require a calibraĆ

tion adjustment to compensate for variations in touch panel alignment and user

preferences.

Configuration settings are stored in CMOS.  If CMOS contains invalid informaĆ

tion, the program displays the calibration screen, regardless of the existence of

the calibrate command-line option.
CALIB.EXE is a DOS application program and can be invoked from the AUTOĆ

EXEC.BAT file or from the DOS command line.  The appropriate mouse driver

must be installed.  The driver contains extensions to the standard Mouse API

which provides digitizer information, screen resolution, and raw coordinate

points, which is required for this implementation of CALIB.EXE.

CALIB.EXE begins the calibration process by placing one of four targets at a

fixed location on the screen and waits for the user to press the pen at the center

of the target three times.  It is important during this process to apply moderate

pressure while pressing the target.  Lightly tapping or placing too much pressure

generates incorrect results.  The unit beeps after each successful press of the

pen.  Therefore, if a beep is not heard when the pen is down, lift and press again.

Also use care to not allow fingers or any other object to touch the screen.  When

the program has acquired three good data points for the target, it then displays

the next target.
When data for all four targets are acquired, the program then displays a screen

which checks the calibration results.  Check the match of the cursor with the

location of the pen near the four corners of the screen.  The best way to do this is

to place the pen down near each corner of the display and see if the cursor apĆ

pears at the location of the pen.  If the cursor is offset from the pen location by

some fixed amount, adjust it by pressing the appropriate UP, DOWN, LEFT, or

RIGHT buttons on the screen.  (The user may prefer to add some amount of offĆ

set to place the cursor away from the pen using the same buttons.)  If the cursor

position varies significantly from the pen location, as the pen is placed at the difĆ

ferent corners, the four target calibration process was not successful.  Restart the

program and pay closer attention to how the pen is pressed against the targets.
