User Manual

To recharge the battery, plug the mini USB cable into the slot on the top of the meter. Plug the
USB A end of the cable into a PC, USB wall plug, USB power bank or any standard mobile
phone USB A charging device. The ILT770 will always turn on when power is supplied via the
mini USB. It will take approximately 4 hours to charge the ILT770 when the battery is drained.
The meter can be used while charging the battery.
Battery replacement cannot be done in the field. Please contact your sales representative to
schedule a battery replacement.
6. SENSOR
The ILT770 has been paired with the sensor and calibrated to create a NIST traceable
calibrated light measurement system. Swapping sensors between meters can cause
inaccurate results. Please verify your meter and sensor serial number on your calibration
certificate if there is a chance your have swapped sensors.
The sensor includes a standard male BNC connector, a 3 foot cable and an integrated
sensor/filter/optic in a low profile 42 mm diameter by 15 mm tall housing.
To attach the sensor locate the female BNC connector on the top side of the meter. Align the
connectors, press down and twist to lock the sensor in place. The meter is designed so that
the sensor can be detached when not in use, or left attached at all times.
The sensor opening must be completely filled with light. The surface of the opening should be
placed perpendicular to the light source and should be at the same distance from the source
as the product being irradiated.
The Sensor is not water proof and should not be submerged. Liquids should be used very
sparingly when cleaning the sensor to prevent possible damage.
Sensor replacements are available. Replacing a sensor requires calibration at the factory.
7. USB PORT
On the top right side of the meter is the Mini USB port. The USB port is used for both
charging the device and for downloading stored data to a PC. We recommend using the
supplied USB cable or any good quality mini USB cable.
8. CALIBRATION
An annual calibration is typically recommended for all light measurement equipment,
however, the end user may, through their own QC process, create their own calibration cycle.
