3x.
Press to measure the length of the hypotenuse (a).
Press to measure the length of the base-side (b).
The meter will automatically calculate the length of the leg (x).

FUNC
4x.
Press to measure the length of the leg (a).
Press to measure the length of the base-side (b).
The meter will automatically calculate the length of the hypotenuse (x).
(3) Press FUNC 5x, the hypotenuse flashes
Press to measure the length of the hypotenuse (a).
Press to measure the length of another hypotenuse (b).
Press to measure the length of the base-side ©.
The meter will automatically calculate the length of the leg (x).
(4) Press FUNC 6x, the hypotenuse flashes
Press to measure the length of the hypotenuse (a).
Press to measure the length of the base-side (b).
Press to measure the length of another hypotenuse ©.
The meter will automatically calculate the length of the leg (x).
In the Pythagorean measurement mode, the length of the leg must be
less than the length of the hypotenuse; otherwise the meter will display
an error signal prompt. In order to ensure the measurement accuracy,
users should make sure to measure from the same starting point and in
the order of hypotenuse and leg.
6. Addition/Subtraction
The single distance measurement values can be added or subtracted. After
getting the result when taking a single distance measurement, press to
enter the addition/subtraction mode.
Short press +, the "+" symbol will show on the primary display, and then it
will enter the addition mode. The addition value of the last and the current
measurement values will show on the display.
Short press , the "
﹣"
symbol will show on the primary display, and then
it will enter the subtraction mode. The subtraction value of the last and the
current measurement values will show on the display.
Not only the distance can be added and subtracted, but also the area and
the volume.
Area addition: Measure the first area and get the result, as shown in Figure 1
below. Then press to measure the second area and get the result, as
shown in Figure 2 below, and a plus sign will be displayed in the lower left
corner. Finally, press to get the result of adding these two areas, as shown
in Figure 3. The addition and subtraction of volume is similar to it.
7. Data Storage
If the current data is valid when measuring, press and hold for 3 seconds,
and the data will be automatically stored in the meter memory. In the area,
volume and indirect measurement modes, the data can also be stored after
all the tests are over. At this time, the meter will store the complete
measurement record under this mode.
8. View/Delete Data
Short press to query the stored data. Press + to scroll forwards, and press
to scroll backwards. When viewing data, short press to delete the
current record, and long press to delete all records. Press or to exit.

** Under harsh environments, such as excessive sunlight and ambient
temperature fluctuations, weak reflection on reflective surfaces, and
insufficient battery power, the measurement results will have errors. At this
time, using the target reflector can improve the measurement accuracy.
Maintenance
Do not place the meter in a high temperature and humidity environment for
a long time. When not using the meter for a long time, please take out the
battery and put the meter in the carrying bag, and store it in a cool and dry
place.
Remove dirt with a moist, soft cloth. Do not use aggressive detergents or
solutions. The laser window and focusing lens can be wiped according to the
method of wiping the optical device.
