Lithium-ion Polymer Batteries
This measuring tool is powered by a built-in 3.7V 850mAh lithium-ion battery
which cannot be removed. As an improved version of ordinary lithium-ion
batteries, Li-ion polymer batteries are rechargeable batteries that use
colloidal or solid polymers instead of liquid organic solvents, having a great
improvement in life extension, energy density, safety, and charging speed.
This measuring tool has its own charging circuit with clear Battery Low
Indicator and Charge Indicator.
Battery charging: Please use a good-quality charging head,output: DC5V 1A
, it is recommended to use the charging head of mobile phone.
After the battery has been used for a period of time, the capacity is reduced
and the power is insufficient, so the tool can’t be turned on normally, or after
the tool is turned on, the battery symbol is blank or flashes, at this time
please charge the battery in time.

The measured value is displayed in the result line.
For several subsequent length measurements, the last measured results
are displayed in the measured-value lines.
The current measured value will be displayed in the result line.
MAX/MINMaximum/Minimum value: All measured values are
automatically saved, in which the maximum value and the minimum value
will be displayed directly in the measured-value lines.
Pressing the measuring button or the wheel measuring button once
to end the continuous measurement. The last measured value is
displayed in the result line.

Press the same button once to measure the 2nd width( width 2), the
sum of two areas will be automatically calculated and displayed in the
result line.
Indirect height measurement / Simple Pythagoras Measurement
The indirect measurement is used to measure distances that cannot be
measured directly because an obstacle would obstruct the laser beam or no
target surface is available as a reflector. Correct results are achieved only
when the right angles required for the respective measurement are exactly
adhered to Pythagorean Theorem(a²+b²=c²).
There are four Pythagoras modes specially-designed for users to measure
conveniently.
1.
2.
3.
4.
In Simple Pythagoras Measurement, the measuring tool can only calculate
when the side of right angle is shorter than the hypotenuse, otherwise, it will
display “ERROR”. In Simple Pythagoras Measurement, in order to ensure
the accuracy of measurement, it is necessary to ensure that the measuring
tool is measured from the same starting point, and follow the measure order
indicated on LCD.
Wheel Measuring
Switching on the laser tape measure, press the button for 3 seconds to
enter into the Wheel Measuring Mode. The symbol will show on LCD,
indicating that this tool enters into Wheel Measuring Mode for measuring the
length of curved surface. Rolling its wheel along the line to be measured and
the the result value will display in the result line, in this way you can measure
curved line or straight line in any kind of surface. It’s better to draw a line
firstly on the surface to be measured to make sure the route you are going to
roll along.

Specifications
“d”represents the actual distance
In an unsuitable environment, such as too strong sunlight or too large
fluctuation of ambient temperature, the reflection effect of the target surface
will be weak, which will affect the measurement results. In this case, the
hand-held reflector should be used to cooperate with your measurement to
obtain better effect.
When the battery power is insufficient, the measurement result may occur
errors, so please charge it in time.
