Safety information
• To avoid injury or re hazard, do not use this product in an explosive atmosphere.
• To avoid eye injury, wear eye protection if there is a possibility of exposure to high-intensity rays.
• Do not immerse in liquids, clean the sensor head using only a damp cloth.
• Cover sensor head when not in use to extend silicon photo-diode sensor life.

1Remove the sensor cover on the backside of the UV-A meter
2Switch the meter on by pressing the MEAS button
3Select the range by pressing the RNG button twice to Hi, so
you will see two decimals behind the decimal point (ie: 0.00).
This will now measure from 0 to 19,99 mW/cm2
4Press the MAX button so you will record the highest
output value shown in the display. MAX will appear
in the display at the top of the screen.
5Now swipe the sensor head (white – round head) slowly
along the glass of the lamp from left to right. The sensor
head should be touching the glass during this operation.
6Then press the HOLD button. H will appear in the top
of the screen (This step is optional if you have pressed
the MAX button, but it holds the reading longer in the
display).
7Now you can read the UV-A output value.
8To take the next reading, press HOLD button
again to turn off HOLD (It now disappears from
the top of the screen). Press also MAX to clear
the reading.
Then repeat step 1 to 7 above.
Prior to taking a UV-A reading, make sure that the lamp has been working for at least 5 minutes.
Depending on the ambient temperature, it can take up to 5 minutes for a UV-A lamp to reach
its full UV-A output.

Lamp is effective: (strong y attractant UV-A spectrum)
5 mW/cm2 (3 mW/cm2 for Basic Line) is required min. UV-A output, which ensures that the unit
stands out from its environment and insects notice the light in the perimeter around the y control unit.
Lamp needs replacing (ineffective y attraction level).
