PWM is the abbreviation of Pulse Width Modulation, and 

refers to the method of controlling signal intensity by 
controlling the ratio between the ON period and OFF period 

of a pulse signal.

A pulse signal is a signal which repeatedly alternates 
between ON and OFF, and the percentage of ON period 

during a single cycle is referred to as the "duty cycle". 

PWM-controlled lighting is a method for controlling the 

brightness of a lamp by controlling the duty cycle (lit time) of 

light from a pulse-emission source. As the lit time becomes 

longer, the light becomes brighter, and conversely, as the lit 

time becomes shorter the light becomes darker.

Period when LED is lit

Measurements of up to 30 points can be controlled. A CCF 

(Color Correction Factor) function is also provided to enable 

calibration to user standards. 

Reads measurement data from T-10A series Illuminance 

Meters directly into Excel

®

. Further processing of data can 

then be performed easily using the various functions of 

Excel

®

.

When using T-S10w, 

measurements can be taken 

and data sent to Excel

®

 by using 

not only the computer keys but 
also by using the buttons on the 

T-10A main body.
