FIGURE 1:
UV LIGHT METER OPERATION
1. Turn the meter on by pressing the POWER BUTTON
(3-2, fig. 1).
2. Zero Adjustment: Set the RANGE SWITCH
(3-7, fig. 1) to 199.99. This is the far left setting. Cover
the UV SENSOR (3-8, fig. 1) with hand to protect
it from the environment for a more accurate zero
reading. Press the ZERO BUTTON (3-6, fig. 1). The
display should read 0.0. Remove your hand.
NOTE: if the display shows: “CALO” the further
adjustment is needed. Turn the power off by pressing
the POWER BUTTON. Press and hold the ZERO
BUTTON. Press the POWER BUTTON again. The
bottom line of the display will show “0000”. Adjust the
VR9 by turning the knob on the right of the unit until
the top line of the display reads “0”.
3. Select the desired range by switching the RANGE
SWITCH (3-7, fig. 1) NOTE: If the display shows “----”
then there is too much light for the meter to read in
this range. Select the next higher range.
4. Place the UV SENSOR (3-8, fig. 1) directly under the
light source you wish to measure. Hold for at least 0.4
seconds. The meter will measure the light and display
the value. Limit the angle of light from the source
being measured to 45 degrees; if possible, limit the
angle of light to within 30 degrees.
5. To hold a measurement on the display, press the
HOLD BUTTON (3-3, fig. 1) while a measurement is
being taken. The LCD will show DH in the upper left
portion of the display to indicate that the value is a
“held” value. To cancel the data hold feature, simply
press the HOLD BUTTON a second time.

6. To record a measurement, press the RECORD
BUTTON (3-4, fig. 1) while a measurement is being
taken. The LCD will show REC in the lower left portion of the display to indicate that the value is being
recorded. To deactivate the record function, press the
RECORD BUTTON again.
7. Memory Recall: Use the RECALL BUTTON (3-5, fig.
1) to recall the minimum and maximum readings.
When the REC symbol appears or the display,
press the RECALL BUTTON (3-6, fig. 1) once. The
maximum recorded value will be displayed. The
letters “Max” will also appear on indicating that this
is the maximum or highest reading. A second press
of the RECALL BUTTON will display the minimum
reading. The letters “Min” will also appear indicating
that this is the minimum lowest reading.
Note: The Data Record function must be in use to
utilize the Memory recall features. Once the RECORD
BUTTON has been pressed a second time to
deactivate the data record function, the minimum and
maximum values are no longer stored.
CARING FOR THE UV LIGHT METER
It is recommended that the meter be recalibrated every
year. The sensor is extremely sensitive to humidity. Store
in a low humidity environment by keeping it in its case
with the Humidity Sponge™ provided. Proper storage
will extend the length of time between recalibration of
the unit.
ALL OPERATIONAL DIFFICULTIES
If this Ultra Violet Light Meter does not function properly
for any reason, please replace the battery with a new
9-Volt alkaline battery (see Low Batt section, above).
Low battery power can occasionally cause any number o
“apparent” operational difficulties. Replacing the battery
with a new fresh battery will solve most difficulties.
COMPUTER SERIAL INTERFACE
This unit features computer output. A COMPUTER
OUTPUT SOCKET (3-11 fig. 1) is located on the top
of the unit. To utilize this feature, connect the unit to a
PC with an accessory Data Acquisition System. See
Accessories.

alkaline battery. Use an alkaline battery, NOT a regular or
heavy duty battery. Property connect the battery. Replace
the battery cover. Incorrectly installed batteries may
damage electronics.
The unit has an automatic shut off feature to prolong
battery life. If no button on the unit is pressed for ten
minutes, the unit will automatically shut off. To deactivate
this feature, press the RECORD BUTTON while a
measurement is being taken.
