The arrangement for minimum range setting is designed to facilitate
identification of individual signals reflected from targets and other objects in
the path of the laser beam.
By using this arrangement an operator is able to not receive (i.e. reject) signals
reflected from objects within a given minimum range (gated range). A value of
gated range can be set within 40...4500 m. For this purpose:
- set the MODE switch to the C position;
- switch on the ON switch;
- observe the value of minimum range in the left eyepiece;
- continuously rotating the MIN RANGE handle set a required value of
minimum range;
- set the MODE switch to the F position and measure the range to a target as
explained in 5.2.
Due to the fact that a portion of the transmitter beam is intercepted by objects
in front of a target, a signal from the target can be lower than the level of
operation of the rangefinder receiver, so, when measuring range, sight the
rangefinder on a target so that as few objects in front of the target as possible
are within the transmitter beam.
If the C -indicator lights, this means that one or more targets (without
indication of their number) are gated out by the minimum range setting.
