SELECTING DOT AREA OR DOT GAIN
1. If this is your first time selecting a measurement function, you
should plug your instrument in using its AC adapter. This will
prevent the microprocessor from going into “sleep” mode to
save battery power. With the instrument plugged in, you’ll be
free to take your time learning this procedure.
2. Next, make sure you have the desired response setting selected,
and that the instrument is properly calibrated. These procedures
are covered in the previous chapter, “Calibration.”
3. To select the measurement method for measuring ink density,
press the FUNCTION button repeatedly until DOT AREA or
DOT GAIN appears in the display (each time you press the
button the display toggles between DEN and DOT AREA or
DOT GAIN).
4. If DOT AREA appears and you wish to select DOT GAIN, press
and release the ZERO button to toggle the selection. Do the
same if DOT GAIN appears and you wish to select DOT AREA.
