Klein K10-A Colorimeter Guide

The K10-A is a reference class non-contact optical colorimeter with superb accuracy, the fastest read times available, superior performance at low light, and extremely high light level measurement capability (0.0002 to 10,000 cd/m²).

Klein K10-A Included Parts

  • Rubber Lens hood – to be used with the K10-A, or together with the extension tube, to make screen contact when measuring a flat panel display.
  • Cosine diffuser – To be used with the K10-A when pointed directly at a projector.

Device Driver Installation

The Klein K10-A uses the FTDI device driver.

  • Included in Calman Device Driver Pack 2.4: Link
  • Single FTDI device driver: Link
  1. Install the Calman Device Driver Pack or FTDI driver
  2. Plug the Klein K10-A into a USB port on your computer. Windows should automatically detect the K10-A device driver if you have installed the Calman Device Driver Kit.
    1. When the driver is properly installed, the Klein K10-A will be listed in Device Manager under Universal Serial Bus Controllers as USB Serial Converter
    2. The Virtual COM Port (VCP) driver also causes the Klein K10-A to appear as an additional COM port, listed under Ports (COM & LPT), as USB Serial Port (COMx)
    3. If the Klein K10-A does not appear under those two listings, the driver is not yet properly installed.
    4. Calman software can then access the Klein K10-A as it would a standard serial device, at the COMx port.
If the USB driver does not install properly:
  1. Right click on Computer/My Computer and select Properties. Or, go to the Control Panel and open Device Manager.
  2. In Device Manager. In the menu tree, you will see a USB serial device that is not working properly (yellow exclamation mark).
  3. Right-click on the conflicted device and select Update Driver.  Select Install From A Specific Location, then browse to the FTDI folder in the C:Program Files (x86)SpectraCalDrivers directory.  It may ask you to install the driver twice; this is normal. Go through the same process and the same location for the driver.

Calman Connection to Klein K10-A

To connect Calman to the Klein K10-A meter.

Meter Positioning

Flat Panels and Rear-Projectors

The K10-A ships with a rubber lens hood that can be used to position the K10-A right up against a display screen. The soft rubber hood will not damage the screen. Because it blocks all ambient light, the lens hood makes the K10-A ideal for measuring reflective displays such as plasmas.

Front Projectors

The K10-A should be placed along the line of sight from the main/central viewing location, pointed at the center of the projector screen. In other words, the K10-A should measure the screen from the same angle that the screen is normally viewed.

The K10-A should be placed close enough to the screen so that its measurement area is contained entirely within the screen test pattern area. This can be determined by enabling the meter LED pointers.
