Reference Setup
The default reference setting: the bottom of the instrument.
Press to switch the reference point between the top,
bottom, tripod, and end-piece of the instrument. There is a
beep warning tone when a reference point is changed.
The reference point will return to default every time when
the unit is powered off.
I.E. the measuring reference point is from the bottom of
the instrument every time when it’s powered on.
Single Measurement
Press to activate the laser.Aim the laser at the object which is to be measured and press
again to take measurement. Results will be seen on the screen’s display immediately.
Continuous Measurement (max/min distance)
Long press to activate continuous measurement. Under this mode minimum or maximum distance
can be measured from a fixed measuring position by sweeping ideal points.
Note: Continuous measurement will stop after 5 minutes.
Area Measurement
Press once to activate area measuring function. The symbol will appear on the display.
Press to take the first side distance measurement (e.g. length).

Press again to take the second side distance measurement (e.g. width).
The results of length, width, perimeter, and area will be seen on the display.
Volume Measurement
Press twice to activate the volume measuring function. The symbol will appear on the display.
Press to activate the laser, and aim at the target. Press again to take the first side distance
measurement (e.g. Length). Then, respectively press to measure the width and height. The
resulting volume will be display in the summary line.
Addition/Subtraction
Distance
1. Take a measurement of a distance.
2. Press the addition button . The next measurement’s data will be added to the former one.
3. Press the subtraction button . The next measurement’s data will be subtracted from the former
one.
This operation can be repeated. The results will be displayed in the main area of the screen.
Area/Volume
1. First take a measurement of area or volume.
2. Press the addition button , and measure the second area/volume. This measurement will be
added to the former one.
3. Press the subtraction button , and measure the second area/volume. This measurement will be
subtracted from the former one.
Indirect Measurement
This device can measure distance to inaccessible points, such as the distance to a wall which is blocked
by obstacles or the height of a tree, using a trigonometric function. To ensure measuring accuracy,
indirect measurements should be based on the following conditions:
(1) The measuring points of the object which is to be measured should be on the same horizontal or
vertical line.
(2) Put the device at a fixed but horizontally and vertically rotary tripod.
Indirect Measurement: Pythagoras Two Points
As shown (Figure A), if a user wants to measure the height of the pink line, he can use Pythagoras Two

Points to calculate the height.
1. Press three times. The symbol will appear on display.
2. Press to activate the laser and aim at the point which is to be measured.
3. Press again to take the first measurement (1), and then again to
take the second measurement (2).
4. The height of the pink line (third side of triangle), first, and second
distance values will be seen on display.
Figure (A)
Note:
(1) The device will automatically determine the longer distance as the triangle’s hypotenuse, and the
shorter distance as the right-angle side.
(2) When measuring the right-angle side (Distance 2 in FigureA), user should ensure laser beam is
right-angled to the target line.
Indirect Measurement: Pythagoras Three Points
As shown in Figure (B), if the user wants to measure the height of the pink line, he can use Pythagoras
Three Points function to calculate the height.
1. Press four times. The symbol will appear on the display.
2. Press to activate the laser and aim at the point which is to be measured.
3. Press again to take the measurements from first (1), second (2), and to
third (3) points.
4. The height of the pink line, first, second, and third distance points’ values will be
seen on display.

Figure (B)
Note:
(1) The device will automatically determine the longer distance as triangle’s hypotenuse, and shorter
distance as the right-angle side.
(2) When measuring the right-angle side (Distance 2 in Figure B), the user should ensure that the laser
beam is at a right-angle to the target line.
Angle Measurement
Press button . The symbol will appear in the function field. As shown in Figure (C). Press
to measure the tilt and the distance.
Figure(C)
Auto Horizontal Measurement
Figure (D)
Press twice. The symbol will appear on the display. Press to measure the tilt and

on display. Refer to Figure (K).
Auto Height Measurement

Figure (E)
Press three times. The symbol will appear on the display. Press button to measure the
distance to the top of the object, bottom of the object, distance of two hypotenuse, and the height of
object. The results will be seen on the display. Refer to Figure (E).
Triangle Area Measurement
Figure (F)
As shown in Figure (F), press four times. The symbol will appear in the function area. Press
button to measure the three sloping sides respectively. The area of triangle will be displayed in the
result bar.

1. Range: The maximum measuring range is determined by the version of the meter. Exact measuring

range for the laser distance meter is shown on the gift box. In poor daylight or reflection conditions,
please you the target plate or a better reflective surface.
2. Accuracy: In optimal conditions (good target surface properties and room temperature) the
measuring range is up to 328’ (100m). In unfavorable conditions (intense sunshine, poor reflectivity
in target surface –i.e. a black surface, or high temperature variations) the deviation over the entire
328’ may increase.
