8 Check the settings and click Measure.
The Information dialog box appears.
9 Place the ES-1000 in the calibration cradle.
When you place the ES-1000 in the calibration cradle, white point calibration is used to
calibrate the spectrophotometer and compensate for gradual drifts in the instrument. Make
sure the sample aperture is in full contact with the white tile on the calibration cradle. If you
do not place it correctly in the calibration cradle, the spectrophotometer does not return
accurate measurements.
10 Click OK.
The Measurements dialog box appears. Instructions for measuring the strips appear in the
Status field.
11 For a more accurate measurement, place several sheets of plain white paper beneath the
measurement page.
The extra sheets block underlying colors from being read by the instrument.
12 Orient the measurement page so that strips are horizontal and the scan direction (indicated
by the arrows at the beginning of each strip) is left to right.
13 Hold the ES-1000 with its length perpendicular to the scan direction, and place the sample
aperture in the white space at the start of the specified color.
14 Press and hold the Measure button and wait for a beep or wait for the background color in the
dialog to change from green to white.
N : To hear a beep with a Windows compatible computer, you must install a sound card
OTE
and speaker(s). You may have to turn up the volume on your computer to hear the beep.
15 After you hear a beep or see the dialog background color change, slide the ES-1000 at a slow
but consistent pace across the strip.
