Tapping the “MODE” key once more will advance the unit to SCREEN #3.
SCREEN #3 will scroll “Intensity xxxx” to indicate absolute UV measured intensity

times 10, in µW/cm where “xxxx” is the value of measured intensity in µW/cm x 10.
For example:
SCREEN #3: “Intensity 1234” (the absolute measured
2
intensity is 1234 x 10 – 12,340 µW/cm ).
Tapping the “MODE” key once more will advance the unit to SCREEN #4.
SCREEN #4 will display “dxyz” to indicate the number of days elapsed since
the baseline* reset where “d” signifies days and “xyz” is the measured value
of days elapsed.
For example:
SCREEN #4: “d321” (the lamp has been used for 321 days
since the baseline* reset).
*This is to reset the baseline of all measurements with the exception of the absolute intensity
measurement (SCREEN #3).
Tapping the “MODE” key once more will advance the unit to SCREEN #5.
SCREEN #5 will scroll “Hold To Reset”. By holding down the “MODE” key for more
than 3 seconds the radiometer will reset the lamp percentage’s reading to 100%
and days elapsed to 0.

Mounting the Sensor
Mounting the Controller
If this option is installed, a linearized analog voltage is output with the following
end points:
The data logging voltage will be set according to the baseline reset procedure
outlined above.
The UV sensor must be mounted facing the lamp(s), approximately 3-10” (8-25 cm)
away from the lamp(s). If the radiometer displays “Sensor Saturated” – the sensor
2
has detected UV intensity greater than 21,300 µW/cm . Move the sensor away from
the lamps until this condition is resolved.
Using two screws, mount the sensor on a at, clean surface where no water will drip
directly on the sensor.
For optimal performance be sure to keep the sensor clean. To clean the sensor, we
recommend using a cotton swab and isopropyl alcohol with compressed air.
The controller should be mounted outside of the air handling unit.
Mount in an area with a temperature less than 50˚C and 90% RH.
Mount on a at, clean surface within the range of the cable.
Use two or three screws to mount the controller by using the keyholes in the
back of the controller.
Connect the sensor to the output port of the controller using the supplied cable
Connect power to the controller
0% = 0 Volts
100% = 10 Volts ± 500 mVolts
