5. Operating instructions
• Press the power button ‘ ’ to turn on the meter.
• Press the ‘W/B’ button to select measurement range W/m²or BTU/(ft² × h).
• Remove the protection cap of the photo detector and expose it to the light source in horizontal position. Read the
photometer value from the LCD display.
• After the luminosity value has stabilized. Press ‘HOLD’ button to hold the testing data (NOTE: If display shows ‘OL’, it
means that the input signal is too strong and a higher range must be selected.)
• After the measurement is completed, cover the protective cover, the LCD display should be displayed at ‘000’, if not please
