Returned Signal Checking - Sokkia 30R Series Operator's Manual

11. DISTANCE MEASUREMENT
11.1

Returned Signal Checking

• Check to make sure that sufficient reflected light is returned by the reflective
prism sighted by the telescope. Checking the returned signal is particularly
useful when performing long distance measurements.
• When the light intensity is sufficient even though the center of the reflective
prism and the reticle are slightly misaligned (short distance etc.), "*" will be
displayed in some cases, but in fact, accurate measurement is impossible.
Therefore make sure that the target center is sighted correctly.
PROCEDURE
1. Allocate the [AIM] softkey to the
Meas mode screen.

The intensity of the light of the
returned signal is displayed by a
gauge.

the greater the quantity of
reflected light.
• If "*" is displayed, only enough
light for the measurement is
returned.
• When "*" is not displayed,
accurately resight the target.
Press [BEEP] to make a buzzer
sound when measurement is
