4.2 Start-Up
Turn on the Densitometer. The on/off control is a push-button switch located on the left
front of the unit. The Power indicator lights up. The Densitometer performs a self-test
that lasts approximately 35 seconds during which the Ready indicator flashes briefly. The
scanning lamp turns on and both indicator lights will stay on once the Densitometer is
powered up.
For optimum performance, allow the Densitometer to warm up for five minutes after
power-up.
The Model GS-800 Calibrated Imaging Densitometer is now ready for use.
4.3 Reflective Scanning
To scan a reflective sample:
1.
Raise the Transparency Module.
2.
Place the sample to be scanned facedown on the image window.
3.
Guide the top corner of the sample to the lower left ( 0,29 ) corner of the image window.
4.
Lower the Transparency Module
Warning
: Always lower the transparency module slowly and release it only when it lies
flat on the body of the Densitometer.
5.
For more information about scanning operations and options, refer to the Quantity
One software manual.
Note:
The Reflective density values for the Reflectance Calibration strip are already
included as default values in the software so you do not need to enter them to calibrate the
instrument. Keep the image window clean and free of oil and fingerprints. See Section 5,
Maintenance, for cleaning procedures.
4.4 Transmittance Scanning
To scan a transparent sample:
1.
Raise the Transparency Module.
2.
Place the sample face down on the Densitometer's image window.
3.
Lower the Transparency module.
Warning
: Always lower the transparency module slowly and release it only when it lies
flat on the body of the Densitometer.
