The device is designed to measure illuminance pulsation coefficient and illuminance in the visible region of the spectrum (380 ÷ 760) nm.The device has a unique possibility to determine illuminance values in real time mode and calculate accurate values of illuminance pulsation coefficient by a special programme protected by the Certificate of official registration of the program for computer ?2003612397. The integral method of calculation of average illuminance value for calculation of illuminance pulsation coefficient is implemented in the device.
Calculation of readings on the screen of the device is carried out once a second, thus digitisation of a signal from a photosensor is made at a frequency of 3 kHz, clock frequency of the processor 4 MHz, before 12-bit ADC there is an active low-pass filter on 1000 Hz, for suppression of "reflections" at digitisation there is a digital low-pass filter on 400 Hz.
