1. Using Table 1 establish the measuring distance point from the fly trap.
2. Press either button labelled 'Amb' (Ambient) or 'Trap' to turn the meter on – The
LED's will illuminate in a sweeping motion form left to right and back again,
twice. After the sweeping the red LED number 1 will blink on and off repeatedly.
3. To measure the ambient UV light level you must first switch OFF the fly trap.
Point the meter in the general direction of the fly trap at the distance as specified
and press the 'Amb' button. The green LED number 10 will now blink on and
off repeatedly. This indicates that the meter has stored the ambient UV level
of the room.

and will have subtracted the ambient UV level in the room. The result will then
be displayed on one of the 10 LED bar indicators by illuminating a single LED
continuously. Note – the red LED number 1 will also blink on and off repeatedly
to indicate the meter has performed its calculation correctly.
