Klein Instruments K10 and K10-A colorimeters
These are high-speed, very accurate lightweight devices that support either direct monitor contact or use in a
darkened room as a distance unit.
Conguration
Klein K10 and K10-A instruments come from the factory pre calibrated with a display matrix stored as cal le
15. If you have an existing unit, HP strongly recommends that you send your instrument to Klein for
recalibration. However, if you are comfortable with building a calibration matrix and have access to a
spectroradiometer, you can use the Klein ChromaSurf program to generate your own calibration matrix. HP
recommends that you store your custom matrix as cal
le 15, which will be loaded by default when the K10-A
is connected to the display. However, using StudioCal.XML you can specify any cal le for use in calibration,
allowing you to store a custom matrix in any location.
Usage guidelines
Please note the following tips and guidelines when using the Klein K10-A with the display:
● The display may take up to 10 seconds after instrument connection to display the rst calibration menu.
This is normal for this instrument because it is USB-powered and must boot up before it can respond.
● Direct contact measurement is recommended using the K-10 SF Lens Hood. This allows you to calibrate
the display under typical room lighting (though dimmed lighting is still recommended for best black
measurements).
If using distance measurement, HP strongly recommends that you use a completely darkened
environment for calibration.
● If necessary, use ChromaSurf to recalibrate the black level prior to calibration. The K10-A should hold its
black level calibration for an extended period, but if recalibration is necessary, it is a very quick
procedure.
After display calibration, if the display shows the lower grayscale as light gray with little to no shadow
denition, then you need to recalibrate the K10-A’s black level and recalibrate the display.
Photo Research spectroradiometers
The display supports the majority of Photo Research spectroradiometers, including the following:
● PR-655 SpectraScan
● PR-670 SpectraScan
● PR-680 / PR-680L SpectraDuo
● PR-730 SpectraScan
● PR-740 SpectraScan
● PR-788 SpectraScan
The Photo Research instrument must have the USB interface. This is optional on some models but is required
for connection to the display. If multiple interfaces are supported by the instrument, the USB communication
method must be enabled and active.
