OPERATION MANUAL
UV LIGHT METER UV340B
UVA and UVB measurement
Thanks for your purchase of our UV LIGHT METER ,
please read the following instructions carefully and
always keep this manual within easy reach. UV light
meter is with extremely precise structure. Once don’t
use it, be sure to store it in the dry environment. We
suggest you put the whole light meter including
Desiccant into to the plastic bag and seal the bag as
tightly as possible.
Please take the sensor out of the bag only when use it
and replace the Desiccant periodically.
Comply to above method will extend the life of UV
light meter. Otherwise, the gain of the UV sensor may
be decreased and shorten the calibration period.

5. OPERATION INSTRUCTIONS
1) Connect the battery, and then press the button ‘on’
2) Press the range selection switch to desired range.
3) Remove the photo detector cap and face it to UV
light source in a horizontal position.
4) Data-Peak mode: press the ‘PEAK’key to select
PEAK Hold model. When ‘PEAK’mode is selected,
the UV light meter show the peak measuring value on
the LCD. Press the button ‘PEAK’to the ‘ON’, the
peak value will be cancelled.
5) Read the test value from the LCD display
6) When the measurement is completed, replace the
photo detector cap and turn the power selector ‘OFF’.
6. BATTERY REPLACEMENT
1) It is necessary to replace another one 9V battery,
when left corner of LCD display show “”.
2) After turning off the meter, slide the battery cover
and push in the direction of the arrow to open.
3) Disconnect the battery from the instrument and
replace it with a standard 9-volt transistor battery and
reinstate the cover.
4) Make sure the battery cover is secured after
changing the battery.
7.MAINTENANCE
1) The white plastic disc on the top of the detector
should be cleaned with a damp cloth when
necessary.
2) Do not store the instrument where temperature or
humidity is excessively high.
3) The reference level, as marker on the face plate, is
on the top of the sensor.
4) The calibration interval for the sensor will vary
according to operational conditions, but general the
sensitivity decreases in direct proportion to the
product of luminous intensity by the operational
time. In order to maintain the basic accuracy of the
instrument, periodic calibration is recommended.
