The output voltage of the sensor is related to the received radiation. SL 100 instrument is mainly an efficient and easy-to-use instrument: with small size, it has a large display with a resolution of 64*128 pixels involving a very high electronic technology.
Keyboard presentation When being switched on, “measurement screen” is displayed. From this screen, the operator has access to three others screens by pressing on keyboard; return to measurement screen is obtained by activating Function keys Directly associated to text displayed shown above on display, they allow measurement setting.
Accessible from principal measurement screen by successive pushes on key, those different screens allow instrument setting. They also inform users. Brightness To optimize display reading, the operator can : 1. Adjust brightness by pressing function keys. 2. Backlight LCD display for a better reading in a dark place. “No”...
Radiation exposure or global irradiation The instrument measures twice a second the irradiance and displays it, while memorizing minimum and maximum values. From these data, it calculates and displays the measurement duration : average value, radiation exposure or global irradiation. From start screen, the operator have access to energy measurement over a period controlled by timer and clock, he proceeds as follows: Access to exposure measurement and in sunshine control Irr.
New measurement After recording of results in his file, the operator can launch a new measurement. Here are the actions : 1. 1 x A message alerts the operator of a reset of memory backup. 2. 1 x Memory is erasing , visualized by the progress Memory is erased, the operator can launch a new measurement.
Servicing The SL 100 instrument conception allows a reduce maintenance which consists in changing batteries and cleaning the sensor with a cloth slightly dampened. Regular checking Like most measuring instruments, it is strongly recommended to regularly control and calibrate SL100. Return to the manufacturer each year will provide necessary metrological traceability.
