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
2
)
Vis= Visible light (Lux or Foot-candles)
T= Temperature (Centigrade or Fahrenheit)
RH= Humidity (%Relative Humidity)
The unit automatically turns off 10 seconds after the button is released unless a button
is held down for over 5 seconds, this will cause readings to be taken continuously until
a button is pressed.
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 5 seconds for a continuous readout.
Note that the buttons should be pressed firmly for a second or so to ensure reliable
operation.

of inactivity. A round blob shows the unit is in continuous reading mode until a
button is pushed, nothing here means that a single reading is being taken.
The L indicates logging is in operation, W is shown if logged data is wrapped.

Set\Clock\Hide-Unhide.
If a battery symbol appears at B it means that the batteries need to be replaced.
