DATA: Shows the data analysis from when Graph was first pressed, including Min, Max, and
Average.
EXIT: Returns the display to numerical /non graphing mode and clears the previous graph data
from the display.
3. TAKING A MEASUREMENT
The ILT750 sensor is calibrated with the entire surface of the domed diffuser over-filled with
light. The calibration reference plane is the front surface of the housing. When taking an
irradiance or band irradiance measurement, the same conditions should be applied. The light
source to be measured must fully cover the sensor. The sensor should be placed so that the
front surface is at the treatment location and perpendicular to the source.
The ILT750 offers simple operation. Simply turn on the lamp, press and hold button 1 to turn on
the meter, place the sensor in the measurement location and view the results on the display.
3A Measurement Overview:
Long Press button 1 until the meter turns on.
Change the units as needed by pressing button 3.
Turn on the lamp and let it warm up 2 minutes (or longer).
Place the sensor in the measurement location with the front surface of the sensor
perpendicular to the lamp, at the same distance as the patient will be placed.
The meter will begin providing a readout on the display, updating every ½ second.
Press button 4 to graph and analyze the results as needed.
Long press button 1 to shut off your device, or wait 5 minutes and the meter will shut off
automatically to conserve battery life.
(Note: the ILT750 meter is a lamp/light source diagnostic tool. The meter and sensor
head are not intended to be used while a patient is undergoing treatment or to come in
contact with the patient.)
4. GRAPHING
The graph mode is designed to test the uniformity or stability of a light’s output for up to 30
seconds.
The bar graph updates every 1/2 second offering an easy to evaluate, visual response to
changes in intensity over time. The graph can display up to 60 readings (30 seconds) and will
begin to scroll forward showing only the most current 60 readings when used for longer
durations.
If the sensor is moved slowly across a bili-pad/blanket or under a lamp, the ILT750 will map the
uniformity
of the output over the target area. If the sensor is held stationary, graph mode can
verify the
stability
of the lamps output.
