9.2 Battery Control
When the instrument is switched on the green LED
on the right of the ON/OFF switch lights up. When
the battery is exhausted the red LED to the left of
the ON/OFF switch will light up. You should then
immediately replace the battery.
A new alkaline-manganese battery will last for
approx. 60 hours of continuous measuring.
9.3 Preparing the Measurement
Screw the protective filter supplied with the instru-
ment or one of the close-up lenses on the ocular of
the MAVO-SPOT. For measuring either the protec-
tive filter or one of the close-up lenses must be
attached. Connect the MAVO-SPOT with the
MAVO-MONITOR by means of the connection
cable.
Select a suitable measuring range at the
MAVO-MONITOR and switch both instruments on.
9.4 Measuring
View through the ocular of the SLR viewfinder of
the MAVO-SPOT and direct the measuring circle
you see in the viewfinder to the area to be meas-
ured. This area should be illuminated uniformly
and be as large as possible as compared to the
measuring circle.
After that press the memory switch of the MAVO-
MONITOR and read the measuring value on the
display. When the measuring range is exceeded,
switch over to the next higher range and repeat the
measurement.
