INTRODUCTION
The Sper Scientic 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 eects of
overexposure.

2. The secondary display indicates the advanced
functions or data recording (minimum or maximum
reading of the current data set) or your one of your
20 recorded data points.
Meter Function Flow Chart
1. Press MODE to choose the main function
(MAX/MIN/AVG, Zero, Unit, Type or Time). MAX/MIN/
AVG Mode is Normal Mode for this meter and has
several sub-functions as indicated in the diagram on

MODE AND UNIT SELECTION
Mode Selection
1. Press MODE continuously to cycle through MAX/MIN/
AVG, Zero, Unit, Type, and Time Modes, respectively.
Maximum, Minimum and Average/Normal/Current Mode
1. Press MODE continuously to cycle through modes
until you reach MAX/MIN/AVG.
2. The current measured value appears on the
primary display.

The secondary reading displays the outcomes of the
advanced functions or data recording. There ar four
modes of measuring functions. Press Sbutton to change
the mode of measuring: None - Max - Min - Avg.
4. Maximum, minimum and average values will appear
and freeze on the secondary display and will update
only when a new maximum, minimum, or average value
is reached on the primary display. Then the secondary
display updates automatically. The average value on the
secondary display updates according to the detected
maximum and minimum values of the current reading.
5. The Max-Min-Avg values can only be recalled if you
saved each point to the memory. Press Mto save the
current, max, min, or avg value for each data point and
the meter will move to the next data point. The stored
data can hold either one current, max, min, or avg value
for each data point.
6. Press S to reset.
Data Hold
1. While in Normal Mode, press HOLD to freeze the
secondary display value. “HOLD” will appear on the
bottom left corner of the LCD.
2. Press HOLD to cancel Hold Mode.
