Power-saving automatic cut-off
To save power, power to the SET is automatically cut off if it is not operated
for the selected time.
Resume function
When the Resume function is set to "On," and the power is switched off and
then on again, the screen appearing before the instrument was switched off
is redisplayed. Also, all parameter settings are saved. Memory backup
period is about one week, after which the Resume function is cancelled.
EDM ALC
Set the light receiving status of the EDM. While carrying out continuous
measurement, set this item according to the measurement conditions.
• When EDM ALC is set to "Free," the amount of light received is adjusted by
the instrument's EDM ALC. Set to "Free" when the target is moved during
measurement or different targets are used.
• When "Hold" is set, the amount of light received remains fixed until
continuous measurement is completed.
• If an obstacle intermittently obstructs the light beam during continuous
measurement and the "Signal off" error occurs, each time the obstruction
occurs it takes some time for the amount of light received to be adjusted
and the measurement value displayed. Set to "Hold" when the light beam
used for measurement is stable but is frequently obstructed by obstacles
such as people, cars, or tree branches etc.
The EDM ALC setting will automatically be switched to "Free" when the
distance measurement mode is set to "Tracking" (target is moved during
distance measurement).
