ILT770 UV Light Meter Instruction Manual
1. INTRODUCTION
The ILT770 is a hand held UV meter designed to measure both irradiance in Watts per square
centimeter (W/cm²) and dose/exposure in Joules per square centimeter (J/cm²). The system
comes comfingured with one UV sensors and is calibrated as a set (paired meter/sensor).
Sensors cannot be swapped from one meter to the other as this will impact the accuracy of
the readings.
The ILT770 includes, a storage case, mini USB cable, light meter, UV sensor and NIST
traceable calibration with a certificate.
2. BUTTON FEATURES
The ILT770 meter has a membrane panel with four buttons that allows numerous processes.
1 POWER / UNITS
Press and Hold: Turn device on or off
Press: Toggle units of readouts, W/cm²or JW/cm²
Note: The ILT770 is auto ranging and will automatically scale to the correct level. A prefix will
be applied to values below 1W/cm2 ( ie mW/cm2, µW/cm2, mJ/cm2 and µJ/cm2)
2 ZERO / HOLD
Press and Hold: ZERO: Takes a reading and subtracts that value from all future readings.
2A. Dark ZERO: Cover sensor, wait 2-3 seconds, press zero. This is used to apply a
proper zero for the electronics in the working environment.
2B. Ambient ZERO: Place the sensor in the measurement location with the test source
off or covered. .Wait 2-3 seconds for the system to take a measurement of the ambient
light levels. Apply a zero to subtract the ambient from future readings. Turn the lamp on
and measure only the light supplied from the test lamp.
Press: Freezes/Holds the readings on the display
