4.
Press and release the On/Off button on the radiometer’s face plate to turn the unit on.
5.
On the radiometer’s display, the top line displays the light source and the second line displays the mode.
Repeatedly press and release the Light Source button until “Line Array” is displayed in the top line of
the display.

6.
Press and release the Mode button to select the operating mode. Repeatedly press the Mode button
until the mode you desire appears on the second line of the display. The different operating modes are:
Peak Intensity -
Shows the highest intensity in mW/cm
2
seen by the detector during the
measurement and stores that value in the display.
Intensity -
Shows the intensity in mW/cm
2
at the detector during the measurement. This is a dynamic
readout of intensity.
Dose -
Shows the total energy dose in mJ/cm
2
at the detector during the measurement.
Note: This measurement is time dependent.

Taking measurements
Static readings for general process control when emitter and target are fixed and working distances
are greater than 0 mm:
1.
Using a fixed location in the field of the array emissions, place the aperture of the adapter as
close to center as allowable.
NOTE: Repeatable placement is key to getting consistent readings at working distances
beyond direct measurement at the emitter face. An alignment fixture can help ensure
accuracy at these working distances.
2.
Select the measurement mode appropriate for the data required and take readings. To
improve accuracy, it is suggested that multiple measurements be taken and averaged.
