More Information
For more information about collecting, recording, displaying
and analyzing data, refer to the User’s Guide or Online Help
System for the data acquisition software.
Select a Range
To select a range, press one
of the Range Select Buttons
on the sensor. The green
light emitting diode (LED)
for that button will shine.
The sensor continuously
monitors light input, even if
data are not being recorded.
It detects when the light
input is too high for the
selected range. When this
occurs, the LED for the
selected range will blink,
and the LED in the button for the next higher range flashes.
Press the button with the flashing LED to select the proper
range.
