Timer Function; Practical Advice - Bosch GLM 80 Professional Notice Originale

The requirement for a correct area calculation is that the first
measured length (for example the ceiling height A) is
identical for all sub-areas.
Grade measurement (see figure G)
Press the button for grade measurement (3) to bring up the
indicator for grade measurement
of the measuring tool serves as the reference level. Press the
button for grade measurement (3) again to use the sides of
the measuring tool as a reference level and rotate the display
view by 90°.
Press the measuring button (2) to fix the measured value
and transfer it to the measured value memory. Press the
measuring button (2) again to continue the measurement.
If the display flashes during measurement, the measuring
tool has been tipped too heavily to the side.
If the "digital spirit level" function is activated in the basic
settings, the grade value is also displayed in the other meas-
uring functions in line (d) of the display (1).

Timer function

The timer function is useful when the measuring tool should
be kept stationary during measurement, for example.
Press and hold the button for the timer function (6) to bring
up the indicator on the display.
The time period between triggering the timer and starting
measurement is displayed in the measured value line (a).
The time period can be set between 1–60 seconds by press-
ing the plus button (11) or minus button (5).
The measurement is made automatically after
the set time period has expired.
The timer function can also be used for dis-
tance measurements within other measuring
functions (e.g. area measurement). It is not possible to add
or subtract measuring results or carry out continuous meas-
urement.
List of the last measured values
The measuring tool stores the last 20 measured values and
their calculations and displays them in reverse order (with
the most recent measured value displayed first).
To retrieve the saved measurements, press the
button (7). The result of the last measurement
appears on the display, along with the indic-
ator for the measured values list (e) and with
storage space for the numbering of the dis-
played measurements.
If no further measurements are saved upon pressing the but-
ton (7) again, the measuring tool switches back to the last
measuring function. Press one of the buttons for the measur-
ing functions to exit the list of measured values.
To permanently save the currently displayed measured
length value as a constant, press and hold the button for the
list of measured values (7) until "CST" is shown on the dis-
play. An entry in the list of measured values cannot be retro-
spectively saved as a constant.
To use a measured length value in a measuring function (e.g.
area measurement), press the button for the list of meas-

ured values (7), select the desired entry and confirm it by
pressing the results button (6).
Deleting measured values
Briefly pressing the button (8) will delete the last measured
value in all measuring functions. Repeatedly pressing the
on the display. The rear
button briefly will delete the individual measured values in
reverse order.
To delete the currently displayed entry in the list of meas-
ured values, briefly press the button (8). To delete the com-
plete list of measured values and the constant "CST", press
and hold the measured value list button (7) and at the same
time briefly press the button (8).
In the wall area measurement function, a brief first press of
the button (8) will delete the last individual measured value;
a second press will delete all lengths B
the ceiling height A.
Adding measured values
To add measured values together, first perform any meas-
urement or select an entry from the list of measured values.
Next, press the plus button (11). "+" will appear on the dis-
play as confirmation. Then perform a second measurement
or select another entry from the measured value list.
When the sum has been calculated, you can add more meas-
ured values or measured value list entries to this result if you
press the plus button (11) before each measurement. Press
the results button (6) to end the addition.
Information on addition:
– Mixtures of length, area and volume values cannot be ad-
ded together. For example, if a length value and an area
value are added together, "ERROR" will appear briefly on
the display when the results button (6) is pressed. The
measuring tool will then switch back to the most recently
active measuring function.
– The result of a measurement (e.g. volume value) is always
added; for continuous measurements, the measured
value displayed in the result line (c) is added. It is not
possible to add individual measured values from the
measured value lines (a).
Subtracting measured values

Practical advice

General advice
The reception lens (17) and the laser beam output (16)
must not be covered during the measuring process.
The measuring tool must not be moved during a measure-
ment (with the exception of the continuous measurement
; a third will delete

Press the results button (6) to retrieve the sum
of both measurements. The calculation is
shown in the measured value lines (a) and the
sum is displayed in the result line (c).
To subtract measured values, press the minus
button (5); "-" will appear on the display as
confirmation. The subsequent steps are the
same as for the "Adding measured values" sec-
tion.
