Optional accessories
•
Close-up lenses: the MAVO-Spot with the protective filter (standard equipment) placed in front of the lens allows
measuring from distances from 1 m to
∞
. For shorter distances two close-up lenses are available.
•
Close-up lens 1 (Ordering No. M496G): Reduces the measuring distance down to
approx. 51 cm to 1 m
•
Close-up lens 2 (Ordering No. M496G): Reduces the measuring distance down to
approx. 34 to 51 cm
Attention: Take care that allways the protective filter or one of the close-up lenses must be placed in front of
the lens, but one item only. Incorrect measurement values will result, if you attach more than the one filter
or more than one close-up lens.
•
Transport Case (Ordering No. M495G): for storing and transporting the complete set of
MAVO-SPOT plus MAVO-MONITOR and also the two close-up lenses, the USB cable and
spare batteries.
