Spectrocolorimeter «TKA-VD»/02

Spectrocolorimeter «TKA-VD»/02

Spectrocolorimeter TKA-VD is an instrument for the visible range of spectrum. The device is designed to measure chromaticity coordinates and correlated color temperature of the light sources. It can be used as illuminance meter. They are for measurement of the color features, illuminance of the signal lights, light indicator panel, advertising screen, traffic light and etc.

Construction and principle of work

The principle of work of the device is based on measuring of radiation spectrum of a distant source of optical radiation in a visible range of (390…750) nm with further mathematical treatment of the results of measuring by microprocessor.

The device consists of two functional blocks: a BOS and a polychromator, connected with a floppy multi-core cable.

Introduction of front panel:

«ON / OFF» - MAIN POWER SWITCH OF THE INSTRUMENT;
«HOLD» - Data-Hold,
«MODE» - SELECT OPERATION MODES.

Introduction of Rear Panel: battery compartment.


To switch over to another regime use the button “MODE”. It goes around a vicious circle:
1. Depicting of Illumination E, lx and chromaticity coordinates (x, y) (CIE1931);
2. Depicting of Illumination E, lx and chromaticity coordinates (u’, v’ ) (CIE1976);
3. Depicting of tristimulus values X, Y, Z;
4. Depicting of correlated colour temperature TCC, K.

To keep the measured reading on a display press the button “HOLD”.
A letter “H” will ap-pear in the right part of a display. To continue measuring press the button “HOLD” once more.

The following ways of information display are possible:
1) output onto a built-in LCD;
2) output to RS-232 port.
Use the supplied RS232 cable (USB cable), settings are: 115200 Baud, 8 data bits, no parity, 1 stop bit, no handshake.
Platform: Microsoft Windows 95/98/NT/2000/XP/Vista.
The software will automatically find the used port (COM 1...8) after starting the program,
if the instrument is connected to the PC and the power supply.
