Application Notes and User Tips
1. Protective Cap
The protective cap used to protect the light
sensor from damage and creates a complete
dark environment for the meter to self-calibrate
on start-up. When the meter is not in use,
please keep the protective cap in place over the
light sensor. This will prolong the life of
the sensor.
2. Adjustable Sensor
Depending on the application, the
light sensor can be adjusted or
removed from the meter. For
maximum accuracy, allow the light
under test to fall directly on the
sensor as perpendicular as possible
to avoid any false readings.
Note:
Do not expose this meter
to areas of high temperature and
humidity.

Push the Power Button to turn the meter on. To turn the meter off, press
and hold the power button during the countdown cycle from 3 to 0.
2. When turning the meter on it will perform an automatic zero

Note:
Keep the protective cap on the sensor during the automatic zero

properly secured.
