2.2 Measuring
Important!
Gallilux can be measured to a maximum of 2000 Gallilux!
Higher values are not measurable. Measured Gallilux values
in the range 2000-20.000 Gallilux are not correct, but Lux
values are correct.
Point the sensor of the Galli-Luxmeter to the light source. In the
range, 200 Gallilux/Lux the measurement result can be read di-
rectly off the display (drawing 1: item 2). In the range up to 2000
Lux, values must be multiplied by 10. If the measured Lux value
exceeds the measurement range, the figure ‘1’
will appear in the
display and it will be necessary to measure again but with the
switch in a higher range position. After measuring, switch off
the Galli-Luxmeter by turning the switch in the OFF position.
2.3 Maintenance
2.3.1 How to change the battery
The Galli-Luxmeter is equipped with a built-in 12V alkaline bat-
tery type: A23. When the icon for empty battery appears in the
display (drawing 1: item 1), the battery should be replaced to
ensure accurate measurement.
Replace the battery as follows:
•
Put the Galli-Luxmeter in the OFF position.
•
Remove the screw at the back of the enclosure with a proper
size Philips screw driver and carefully remove the back casing.
•
Carefully remove the battery and replace it with the new battery
of the same type. Make sure that the poles are in the right posi-
tion.
•
Place the rear back and screw it on again.
