Instructions Remove the battery compartment cover on the back of the meter and install the battery while paying attention to its polarity. Put the light sensor on a stable surface and the meter at a proper distance to avoid any interference or disturbance to the sensor illumination. Turn the meter on by pressing the on/off key. Press 1 of the 3 "range keys" to select the proper scale according to the intensity of the light. A "1" on the LCD indicates that it is necessary to increase the measure scale. Press the next range key. The decimal point moves through the display and finally the correct value is shown. Wait for about 1 second for the reading to stabilize. After about 5 minutes of non-use, the meter shuts off.
Note: It is recommended to check if the sensor is clean before taking any measurement.
Battery replacement: When battery becomes weak the meter will display a blinking "V". When the low battery indicator appears, the battery has only about 50 hours of working time left. A low battery will result in unreliable measurements. It is recommended to replace the battery immediately. Battery replacement must only take place in a non-hazardous area using an alkaline 9V battery. Turn the meter off, slide off the battery compartment cover on the back of the meter and replace the battery with a new one. Make sure the battery contacts are tight and secure, seat the battery in its compartment and slide back the cover.
