OPERATION:
•
The meter is supplied complete with
a 9V battery. Remove the battery com-
partment cover on the back of the
meter and install the battery while pay-
ing attention to its polarity.
•
Put the light sensor on a stable sur-
face and the meter at a proper
distance to avoid any interference or
disturb to the sensor illumination.
•
Turn the meter on by pressing the
ON/OFF key.
•
Press one of the three "Range keys"
to select the proper scale according
to the intensity of the light.
•
“1. “ on the LCD indicates that it is
necessary to increase the measure
scale. Press the next range key. The
decimal point will move through the
display and finally the correct value
will be shown.
•
Wait for about 1 second for the reading to stabilize.
•
After about 5 minutes of non-use, the meter shuts off.
Note: It is recommended to check if the sensor is clean before
taking any measurement.
BATTERY REPLACEMENT:
When the battery becomes weak, the meter
displays a blinking "V".
When the low battery indicator appears, the
battery has only a few hours of working time
left. A low battery will result in unreliable mea-
surements. It is recommended to replace the
battery immediately.
Battery replacement must only take place in a
non-hazardous area using an alkaline 9V bat-
tery.
Turn the meter off, slide off the battery com-
partment cover on the meter back and replace
the battery with a new one.
Make sure the battery contacts are tight and
secure, seat the battery in its compartment
and slide back the cover.
