in the manual measurement range. This function can be deactivated by pressing the button

The measurement values can be indicated in Lux, FC (foot candle) and Candela. To change the
unit, press the button "Lx/Fc/CD". To change to Candela, press the button "Lx/Fc/CD" for a longer

Using the MAX/MIN function, the respective largest and smallest measurement value can be indi-
cated. In order to deactivate the function, press the button "MAX/MIN" as often as required until
