Storage for the " UV sensor "
UV sensor is with extremely precise structure. Once don't use it , be sure to store it in the dry environment. For example, put the whole sensor including Desiccant ( Drier ) into to the Plastic bag and seal the bag as tightly as possible ( refer the following figure ).
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 decreased and shorten the calibration period. It is also necessary to replace the Desiccant ( Drier ) periodically.

5. MEASURING PROCEDURE
Under the " Lo range " if the " Display show " ", it
1) Push the " Power Button ( 4-2, Fig. 1 ) continuously until
the " Display " ( 4-1, Fig. 1 ) on then release the " Power Button : will power ON the meter.
* After power ON if push the " Power Button ( 4-2, Fig. 1 )
once a while again will power OFF the meter.
2) Select the max. range on the " Range Switch "
( 4-3, Fig. 1 ).
Lo range : 1999 uW/cm^2 x 1 uW/cm^2 Hi range : 19990 uW/cm^2 x 10 uW/cm^2
* 1000 uW/cm^2 = 1 mW/cm^2
3) Hold the " Probe Handle " ( 4-7, Fig. 1 ) & let " UV Sensor"
( 4-8, Fig. 1 ) face to measuring UV light source , then the Display ( 4-1, Fig. 1 ) will show values of UV light on the display reading.
6. MEASURING CONSIDERATION
1) As the " Lo range " is designed & to measure the UV light
values more than 2000 uW/cm^2 . If the measured UV light values more than 1999 uW/cm^2, it should select the " Range Switch " to the " Hi range " to get the exact measuring value.
*
means the measurement value already over range, then should select the " Range Switch " ( 4-3. Fig. 1 ) to the " Hi " position ( 19990 uW/cm^2 range ).
2)Zero Button ( 4-4, Fig. 1 ) can be operated under the
Lo range ( 1999 uW/cm^2 range ) and the display value 100 uW/cm^2 only.

2) Storage for the " UV sensor "
When LCD display shows " " in the left corner,
UV sensor is with extremely precise structure. Once don't use it , be sure to store it in the dry environment. For example, put the whole sensor including Desiccant ( Drier ) into to 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 decreased and shorten the calibration period. It is also necessary to replace the Desiccant ( Drier ) periodically.
7. BATTERY REPLACEMENT
1)
It is necessary to replace the battery. However, in-spec measurement may still be made for several hours after low battery appears.
2) Slide the " Battery Cover " ( 4-6, Fig. 1 ) away from the
instrument and remove the battery.
3) Replace with 9V battery and reinstate the cover.
4) Make sure the battery cover is secured after changing the
battery.
