The ILT770 has the ability to apply meta data to the saved results. See Applying meta data in
chapter 10 software, on page 8.
4 GRAPH MODE
The Graph button has four functions (Start Graph, Stop/Review Graph, Data Analysis and
Exit) that cycle
forward
each time button 4 is pressed. It is not possible to return to a previous
screen.
GRAPH: Changes the display to graphical mode and start plotting the results and temporarily
storing the readings for final data analysis.
STOP: Stops graphing and holds the display showing the last 60 results.
(NOTE: you cannot return to this screen, to save the results, Press 3, Save now)
DATA: Shows the data analysis from when Graph was first pressed, including Min, Max,
and Average.
(NOTE: you cannot return to this screen, to save the results, Press 3, Save now)
EXIT: Returns the display to numerical /non graphing mode and clears the previous graph
data from the display.
ERASE ALL SAVED DATA
Press and hold both buttons 3 & 4 at the same time to delete all saved reading from the
internal memory of the ILT770.
3. TAKING A MEASUREMENT
The ILT770 sensor is calibrated with the sensor aperture over filled with light perpendicular to
the light source. The calibration reference plane is the front surface of the housing. When
taking an irradiance or dose measurement the same conditions should be applied. The light
source to be measured must fully cover the input optics opening with light. The sensor should
be placed so that the front surface is at the treatment location and perpendicular to the
source.
