Single measurement:
Press the 6 button briefly to turn on the device, the device will automatically switch to the single laser measurement interface and
the speaker will emit the current measurement mode;
Point the laser at the target to be measured and press the single measurement button and the measurement result will appear in
the main display area (as shown in FIG 12) and the speaker will inform you of the current value.
Continuous measurement:
press button 6 for a long time to enter continuous measurement mode and the auxiliary display area will display the maximum value
(max) and minimum value (min).
Function selection:
press 5 or 8 to enter the selection mode (as shown in FIG 13) and select the appropriate function;
Press 6 again to enter the appropriate function interface and then follow the mode icon on the display screen.
THE FOLLOWING MEASUREMENT MODES ARE DISPLAYED ON THE SCREEN, ARRANGED FROM LEFT TO RIGHT AND FROM
TOP TO BOTTOM::
Measurement aggregation: in this mode, the values of many individual measurements will be accumulated and the results will be
Subtraction measurement: In this mode, the value of multiple single measurements will be reduced and the results will be display-
Surface measurement: measure the surface of a rectangle. Measure the length and width of the rectangle according to the screen
mode. The results are displayed in the main display area.
Indirect measurement: Using the Pythagorean theorem, measure one anti-rectangular side and one right side respectively and
the device automatically calculates the length of the second right side of the angle, which is displayed in the
main display area Note: during the measurement, two measurements mean that the reference point of the
measurement must remain unchanged and the line between two laser points and three reference points
must be a rectangular triangle, otherwise the result of the calculation will be completely different from the
actual results.
Indirect measurement
from two triangles: when measuring 2 counter-angle edges and 1 right angle edge, ensure that the reference points of 3 me-
asurements remain unchanged and that the right angle edge must be perpendicular to the target edge to be
measured, otherwise the calculated results are completely different from the actual results.
Historical measurement data: In this mode, press 5 or 8 to display the historical measurement data, which contains up to 30 last
Setting a reference point: Set the measurement reference on the front or rear of the device, The last reference setting is default
when the device is switched on
Unit switch: Set the laser unit of measurement to m or in and ft
Voice transmission: Disable or enable the voice transmission function. When the voice transmission function is deactivated, the voice
transmission function on the instrument is cancelled, the instrument retains only the buzzer tone. The default
setting is the last time the device is turned on
