BASIC OPERATION
To take a reading the appropriate yellow button is pushed depending on the
measurement required and the reading is taken.
UV= Ultra Violet (µW/lumen or mW/M

)
Vis= Visible light (Lux or Foot-candles)
T= Temperature (Centigrade or Fahrenheit)
RH= Humidity (%Relative Humidity)
The unit automatically turns off 20 seconds after the button is released unless a button
is held down for over 3 seconds, this will cause readings to be taken continuously until
a button is pressed again.
If the T and UV buttons are pressed together then all parameters are displayed at the
same time. Hold both the buttons down for over 3 seconds for a continuous readout.
RH & T pressed together shows atmospheric pressure and other information (see
below). This only works with later models (Hardware version greater than 13).
