6. Measuring Procedure
1. Connect the "Probe Plug" (4-15) to the "Input Socket" (4-7).
2. Power on by pushing the "Power On Button" (4-2)
3. Range selection:
a) Select the "2 mW/cm2" range by pushing the "2 mW/cm2 Button" (4-5)
b) Select the "20 mW/cm2" range by pushing the "20 mW/cm2 Button" (4-6)
4. Use the hand to hold the "UV Probe Handle" (4-14) and face the "UV Sensor" (4-13) to the
measuring UV light opposite, then the display (4-1) will show light values directly.
5. Data Hold
During the measurement, pressing the "Hold Button" (4-3) will freeze the display value, at the
same time the LCD will show the "HOLD" indicator. To release the Data Hold function, just
press the "Hold Button" again, then the "HOLD" indicator will disappear and cancel the Data
Hold function.
6. Data Record
The data record function records the maximum and minimum readings. Press the “REC”-
button (4-4) once start the Data Record function and there will be a “REC” symbol on the
display.
With the “REC”-symbol on the display:
a) Press the “REC” button (4-4) once, the “REC. MAX” symbol along with the
Maximum value will appear on the display. If intend to delete the maximum value, just
press the “Hold”-button (4-3) once, then the display will show the “REC” symbol only &
execute the memory function continuously.
b) Press the “REC”-button (4-4) again, the “REC. MIN” symbol along with the
Minimum value will appear on the display. If intend to delete the minimum value, just press
the “Hold”-button (4-3) once, then the display will show the “REC” symbol only & execute
the memory function continuously.
c) To exit the memory record function, just press the “REC”-button for 2 seconds
at least. The display will revert to the current reading.
7. Power Off
Pushing the "Power Off Button" (4-2) will power off the meter.
7. Measuring Consideration
1. The "20 mW/cm2" range is designed to measure the UV light values more than 1.999 mW/cm2.
If the measured UV light values are less than 2 mW/cm2, should select the 2mW/cm²-range to
get the exact measuring value.
2. Storage for the "UV Sensor"
UV Sensor is with extremely precise structure. Once don´t use it, be sure to store it in dry
environment.
For example, put the whole sensor incl. Desiccant (Drier) into the plastic bag and seal the bag
as tightly as possible. Take the sensor out of the bag only when use it. Comply to above
method will extend the life of UV sensor. Otherwise, the gain of the UV Sensor may be
decrease and shorten the calibration period. It is also necessary to replace the Desiccant
(Drier) periodically.
