Self-calibration function is provided to ensure the
precision of the device.
After the adjustment, press to save the calibration
result.
For example, the actual distance is 3.780m.
If the measured value is 3.778m, 2mm smaller than
the actual value, the calibration value can be adjusted
up by 2mm on the existing basis with through the
calibration function.
If the measured value is 3.783m, 3mm larger than the

measurement, it is necessary to ensure that the
measurement is taken from the same starting point
and in the order of the hypotenuse and right Angle
side measurements.
The device automatically calculates the length of
one side of the solid triangle (x).
Press seven times, shows on the screen,
the hypotenuse of the triangle flashes
Press to measure the length of the hypotenuse
of a dotted line (a).
Press to measure the length of the dotted line
as shown (b).
Press to measure the length of the hypotenuse
of the other dotted line in the picture (c).
The device automatically calculates the length of
the right Angle side of the solid line (x).
Measure the three dotted edges of the triangle,
and indirectly measure the length of one side of the
triangle.

In measurement mode, if the current data is valid, it
will be automatically stored in memory, and the record
number at the top of the screen will continue to
accumulate.
Record Function
Short press , when \"-\" shows in the major display
area, the device enters subtraction mode. The screen
displays the difference between the last measured
value and the current measured value.
Measure the first area and the result is shown in PIC1.
Then press to measure the second area and the
result is shown in PIC2, and \"+\" will appear in the
lower left corner of the screen. Finally, press to get
the sum of two areas, as shown in PIC3.
Not only length can be caculated by addition and
subtraction, but also area and volume. Take area as
an example:
Short press , when \"+\" shows in the major display
area, the device enters addition mode. The screen
displays the sum of the last measured value and the
current measured value.

Prompt Cause Solution
Signal is too weak
Out of the
measurement range
Use the device within the
measurement range.
Choose the surface with stronger
reflection. Use the reflecting plate.
Signal is too strong Choose the surface with weaker
reflection.
Low battery voltage Charging the battery.

Pythagoras measuring
breaks the rules
Re-measure and ensure that
hypotenuse is longer than legs.
Use the device in the specified
temperature.
Long press to browse the stored measurement
data, use to scroll backward for record, use to
scroll forward for record. While browsing records, long
press to clear all records. Short press or to

* \"d\" indicates the actual distance.
** In harsh environments, such as strong sunlight, large
fluctuations in ambient temperature, the reflecting surface with
weak reflection effect, and low battery, there will be a large
error in the measurement results. In this case, to enhance the
measurement effect, please use the target reflector.
The meter should not be stored in high temperature
and humid environment for a long time. If it is not
used very often, please take out the battery and
place the meter in the portable bag and store it in
cool and dry place.
Please keep the device surface clean. Use a soft
wet cloth to wipe the dust on the surface. Do not use
corrosive liquid to clean the device. Use the same
method as wiping optical devices to wipe the meter
and focusing mirror.
