INTRODUCTION The Sper Scientific UVA/B Light Meter (Model 850009) is a light-weight, portable instrument that measures damaging UV (ultraviolet) light in both natural and manmade environments. The UV Light Meter measures long and medium wave UV-A/B light for applications such as forensics, chromatography, electrophoresis and dermatology. You can use the meter almost anywhere to determine UV light intensity and avoid the harmful effects of overexposure.

In Normal Mode, press and hold M for 2 seconds. “AUTO” appears next to “REC” on the LCD. As soon as the meter reaches 20 data points, the unit will turn off. Maximum, Minimum and Average (Normal Mode) 1. Press MODE continuously to cycle through modes until you reach MAX/MIN/AVG. 2.
MEMORY Manual Recording In Normal Mode, press M to store the current value that appears on the primary display. The flashing DATA(01~20) icon stops flashing for 2 seconds and moves to the next storage location. (Refer to Maximum, Minimum and Average/Normal Mode on pages 10-11 for instructions on saving max, min, and avg values.) Auto Recording To utilize auto recording, you must first set an interval time for recording measurement values.
MODE AND UNIT SELECTION Zero Adjustment 1. Press MODE continuously to cycle through modes until you reach Zero Mode. 2. Cover the sensor. If the main display has a reading other than zero, perform the zero adjustment. MODE AND UNIT SELECTION 5. In Zero Mode, press M to clear data points 0 to 20. Unit Selection 1.
