Device description Light attenuation meter FOTOMETER 2008 consists of modulated light source, lock- in type light detector and control unit. Device measures intensity of light traveling from the light source to the light detector. It makes the device suitable for measurement changes of attenuation of light in the area between the light source and the light detector.
Display content Display on control unit shows measured light intensity value as well as other related information like actual range, measurement mode, selected input filter and so on. The layout of the display is described in the table below. Switching status Mode Overflow status Range number...
Operating device in automatic mode In automatic mode the device switch to more sensitive range, when intensity value decrease below 8 percent of current range. When intensity rise over 100 percent of current range, device automatically switches to less sensitive range. During switching device displays SWITCHING message on the display.
Setting reference To set reference press SET button bellow the reference you want to set. Current intensity value is stored as reference value. Using input filter Light detector has two input filters. Fast filter is intended for measurement of values changeable in time.
