5 INSTRUMENT SETTINGS
5.1.3 Zoom Control (Zoom setting)
The zoom control function is used to select the best optical zoom system based on the scanning
distance, scanning precision, and scanning time. The GLS-1500 is equipped with three types of optical
zoom systems and the ability to change the size of the beam spot according to the scanning object,
which allows you the choice of obtaining a highly precise three-dimensional data or a quick scan.
Select the following two items below according to the scanning conditions.
Selection item (1)
Selection item (2)
The setting will become invalid when the power is turned off. Please set the scanning mode each time
the instrument is used for measurement.
5.1.4 Measuring Distance to the Scanning Object
Rough distance to the scanning object, which is required to set scanning density, is measured as
shown below.
1
Press the [ ] (star) key.
2
Press the [F3] (range check) key.
3
Collimate the scanning object using the sighting collimator.
4
Press the [ENT] key to display the measured distance.
5.1.5 Camera Setting
When scanning, the internal camera automatically takes pictures of the entire scanning area, and
keeps the data in the image file (if [SCAN+IMAGE] or [IMAGE] has been selected. Refer to Chapter
8.2.2 “Setting the Scanning Density”.)
Several photographs are taken in order to cover the entire scanning area. As the scanning area
becomes larger, number of photographs taken will increase.
Also, as the quality of the image becomes higher, the file size will increase. Select the image quality
based on your needs.
Selection item
5.1.6 Contrast Adjust
Adjust the contrast of the display according to the surrounding conditions. The contrast range is from 1
[light] to 10 [dark].
5.1.7 Backlight Adjust
Use the backlight when the display is difficult to read; for example at dusk or when you are inside a
tunnel. There is a switch to keep the backlight always ON or always OFF. When selecting the backlight
is always ON, the brightness can be adjusted. The range is from 1 [dark] to 10 [light].
UNDER 50m
Select when the distance between the instrument and the scanning
object is 50 m or less.
OVER 50m
Select when the distance between the instrument and the scanning
object is over 50 m.
NORMAL Use one optical zoom system. Scanning time is quickest.
FINE Use two optical zoom systems which measure with high precision.
Scanning time is about twice that of NORMAL mode.
SFINE Select the optimum use of three optical zoom systems which measure
with the highest accuracy. Scanning time is three times that of
NORMAL mode.
This function confirms rough distance and is not for measuring accurate distance to the target.
NORMAL Standard image(800x600 pixels) quality mode, small file size
FINE High image(1600x1200 pixels) quality mode, large file size
