Power-saving automatic cut-off/Backlight Off
To save power, power to the SRX is automatically cut off if it is not operated for the selected time.
The backlight will similarly be turned off if the instrument is not operated for the selected time.
However, the backlight will not be turned off when "Backlight" is set to "ON".

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 instrument's ALC will be automatically adjusted if an error
occurs as a result of the amount of light received. Set to "Free" when the target is moved during
measurement or different targets are used.
• When "Hold" is set, the amount of light received will not be adjusted 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.
