17.3 Grade Display
WHY: Some jobsite plans mention the slope requirements in dierent units. Depending
on planning or regional requirements, the plan may require the slope in percentage,
per mill or degree.
WHAT: The GL1425C provides three dierent possibilities to display the slope value:
percentage, per mill or degree. This can be changed in the Settings menu. Changing
the grade display will result in the correct calculation from percentage into per mill
and into degrees accordingly.
HOW: Press the M button (h) to enter the menu. Scroll to >>Grade Display<< and
press the E button (j) to enter the sub menu. Scroll to the desired grade display mode
and select percent (%), per mill (‰) or degree (°). Press E button (j) to conrm the
selected display mode.
>>%<< (default)
>> ‰<<
>> °<<
Note: The grade value for % and ° is shown with maximum two digits after the point.
The grade value for ‰ is shown with maximum one digit after the point.
17.4 Start Grade
WHY: The laser always starts with the latest grade value stored when the unit was shut
o. This is convenient when starting the job at the next day with the same value for
the grade. For some users this is a risk when the laser is shared within dierent teams.
There is a chance that the wrong grade value is used when the user does not check
the grade value before the work starts.
WHAT: Change the settings to start with the previous stored grade value or start with
zero grade.
HOW: Press M button (h) to enter the menu. Scroll to >>Settings<< and press the E
button (j) to enter the sub menu. Scroll to >>Start Grade<< and press the E button (j)
to enter the sub-menu. Choose Saved(default) or 0 Grade.
>>Saved<< (default)
>>0 Grade<<
17.5 Backlight
WHY: Under dark ambient light conditions, the display is often hard to read. A
backlight helps to view the display on the laser and remote control. Using the backlight
too long reduces battery life.
WHAT: Depending on the need of longer visibility for the backlight or saving the
battery life, the laser provides two dierent times to shut o the backlight: 8 seconds
or 60 seconds.
HOW: Press the M button (h) to enter the menu, scroll to >>Settings<<, press the E
button (j) to enter the sub menu. Scroll to >>Backlight<< and press the E button (j)
to enter the sub menu. Choose backlight time of 8 seconds (default) or 60 seconds.
Press the E button (j) to conrm the selection.
>>8 seconds<< (default)
>>60 seconds<<
