    4. Data-hold button ： Press the HOLD button to select HOLD mode. When HOLD mode is selected, the illuminance meter stops all further measurements. Pressing the HOLD button again cancels HOLD mode, causing the illuminance meter to resume measurement. 5. Range button ： Pressing the range button changes from 200 LUX, 2,000 LUX, 20,000 LUX and 200,000 LUX range sequentially.
