Part Ii Chapter 1: Installing The Pc Program - Klein K Series User Manual

3 Title of this help project
To use the K Colorimeter, you must have a
· K Colorimeter
· 5v Power Source (supplied, or plug into a USB port for power)
· Windows based PC with a RS-232 comm port (win 95 or greater)
· Klein K Colorimeter PC program (requires 20M of hard drive space)
K-1 Colorimeter
The K-1 is designed for measuring luminance and color from a diffuse source, such as a CRT. The K-1 is
also useful for taking Lux measurements from a front projector.
K-10 Colorimeter
The K-10 has a +/- 5 degree angular input aperture, and is used for measuring luminance and color from
a directional but partially diffuse source, such as an LCD display or a rear projector display.
Flicker Meter Function Included
Both the K-1 and the K-10 are also fully functional flicker meters. They feed real time data to the pc
program which performs a Fast Fourier Transform and graphs the data as frequency versus amplitude.
Optical Filters
Inside the Klein K Colorimeter are three optical filter sets, one each for CIE X, Y, and Z, and three silicon
detectors.
Electronic Filters, A/D and Microprocessor
Each Optical Filter and silicon detector has its own electronic channel consisting of a 6 step auto-
ranging amplifier and access to a 12 bit A/D with 4 dither steps. The A/D is read 256 times per second
by a microprocessor.
Each electronic channel amplifier has a 3 pole 28 Hz analog filter, which, along with digital the averaging
function, filters out unwanted 60 Hz and faster noise. For flicker measurements, the data is sent as raw
unaveraged 256 measurements per second.
On-board Flash Memory in the Colorimeter
The K Colorimeter will store up to 96 custom calibrations in Flash memory. These are easily accessable
via the Klein Colorimeter PC program. The calibration files can be named by monitor type for ease of
remembering which calibration file is which.

2.1 Installing the PC Program
The Klein K Colorimeter PC Program is intended to be run on pc's with windows 95 and later. The PC
program uses a comm port for communication to the colorimeter, and it uses database functions for data
logging.
