conserve battery life. It is possible to graph for longer than 5 minutes when connected to a
power source, but it is not possible to save more than 95 datapoints.
The bar graph updates every ¼ second offering an easy to evaluate, visual response to
changes in intensity over time. The graph can display up to 60 readings (15 seconds) and will
begin to scroll forward showing only the most current 60 readings when used for longer
duration's.
In Irradiance mode, when the sensor is moved slowly under a lamp, The ILT770 can 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.
In dose mode the graph will show the uniformity of the increase in the dose.
To complete a measurement while graphing, press button 4 (hold). This will freeze/hold the
last 60 readings on the display for review.
Up to 95 data points, or 24 seconds of data at ¼second intervals, can be saved to the internal
memory by pressing button 3 to save the file. You must save the file for the measurement
while the display is in Freeze/Hold mode showing the graph. Once Data Analysis is activated,
the previous graph data is no longer accessible.
Press button 4 a third time to access the Data Analysis Display. The graph will be replaced by
the graph analysis window and provide a readout of the Min, Max and Average readings.
Data Analysis Results can be saved to the internal memory by pressing button 3 to save the
Data Analysis file. You must save the file while the display is in Data Analysis mode. Once
exited, the previous data is no longer accessible.
To exit the graph mode, press button 4 a third time. This concludes the graph measurement
and returns back to the meter back to a numerical measurement display.
Review: Press button 4 once to enter graph mode and take your measurements, Press again
to stop measuring and review graph. Press a third time to review the analysis and press a
fourth time to return to the main display.
5. BATTERY
The battery on the ILT770 includes a 1200 mAh rechargeable lithium battery that will run the
ILT770 for up to six hours of continuous use. The battery is rated to last for 300-500 charge
cycles. To conserve battery life, the ILT770 will automatically shut off after 5 minutes unless
plugged into a power source.
