The F-250 is a high performance, high precision, multi-functional UV illuminance measuring instrument that can measure the maximum optical power, cumulative energy, instantaneous optical power and other parameters.
The measuring probe of this instrument is external, and the measuring spectral range can be divided into: UVA (320-390nm) @365nm; UVV (395-445nm) @405nm; UVV2(445-500nm)@450nm three, customers need to choose the spectral range when purchasing, an instrument can only choose a spectral range can not be both.
Press the power key every time F-250 illuminance meter is used, the machine is turned on after initialization, all data will return to zero, press the RUN key to enter the test state, the LCD screen can display the energy value and light power respectively, press the SELECT key to switch the display of the above different functions, and long press the RUN key to clear the data above zero, detailed parameters see the product specification.
When the measurement is completed, long press the power button to turn off the instrument. The device will automatically shut down without induction or any key action. Correct operation will effectively extend the battery life of the instrument.
