The swivel-head is one of the most advantageous features of this meter. Swivel the
head of the meter to the right or left when the measurement is difficult due to the
position of the surface to be measured.
6. Zero setting adjustment
When the light receptor is completely covered by hand (a condition where no light
enters into the light receptor), the pointer should be at zero. If it isn't, turn the zero
adjusting screw on the back until the pointer comes to the zero position.
7. General Precautions
1) Be careful not to give any shadow on the light receptor at every
measurement.
2) Position the meter (more exactly the surface of Lumidisc) in parallel to the
surface to be measured.
3) Avoid to leave the meter for long hours in a place of high temperature and
humidity.
4) Store it in the case and keep in a dry place when not in use.
