The product is equipped with 3.7V/850mAh lithium battery
which is built-in and non-removable
Please charge it if it can not be turned on or there is no power
indication after starting up.
Please use charging adapter with DC5V and 1A to charge it,
the charging port is the Type C port. (We recommend to use
phone charger).
The battery icon will be displayed in scrollable way during
charging process. The battery icon will be displayed and
flashing when the charging process is completed.
Keep it with full power if no operations for a long time; and
charge it once every half year to avoid the battery damage.

Calculate the length of two legs by measuring the hypote-
nuse and the angle.
Short press four times, when the hypotenuse of
blinking,
Press ,measure the length of hypotenuse (a),and
calculates the angle (α) between the bevel and the bottom at
the same time.
Device calculates the horizontal distance (b) and vertical
height (h).
Calculate the hypotenuse by measuring the length of two
legs.
Short press five times, when one leg of blinking,
Press
, measure the length of one leg (a) Press ,
measure the length of another leg (b) Device calculates the
length of hypotenuse (x)
Press six times till the one side of blinking on the screen.
Press ,measure the length of one side (a)
Press ,measure the length of the median line (b) Press
, measure the length of another side (c) Device calculates
the length of the leg in full line (x)

The device can be used for length addition and subtraction.
Press
to select the function once get the length measur-
ing result.
Short press , "+" shows in the major display area, entering
cumulation mode. Value of last measurement and the result of
cumulation will be showed on the screen.
Short press , "-" shows in the major display area, entering
regressive mode. Value of last measurement and the result of
cumulation will be showed on the screen.
Not only length can be calculated in addition and subtraction,
but area and volume can do the calculation as well. Take area
as sample:
Area cumulative function: Measure the first area as showing in
PIC1. Then press button ,and measure the second area as
showing in PIC2, there is a "+" in the left bottom. At last, press
button
to get the summation result of these two areas
which is showing in PIC3.
Press seven times till the hypotenuse of blinking on the
screen.
Press ,measure the length of one hypotenuse (a)
Press ,measure the length of another hypotenuse (b)
Press ,measure the length of one leg (c)
Device calculates the length of the leg in full line (x)
Legs must short than hypotenuse, or there will be "err"
shows on screen. In order to guarantee the accuracy, please
make sure all measurements are start from the same point.

Note:
Use a target plate to increase the measurement range
during daylight or if the target has poor reflection properties.
Typical Tolerance: ±2mm, when reflectivity 100% (white
surface), environment light <2000 LUX. 25 °C Tolerance is
usually affected by the distance, reflectivity, and environment
light etc. It probably gets tolerance around ±

Please check if the accessories are completed according to the
below list.
The meter should not be stored in high temperature and
strong humidity environment for long time; if it is not used
very often, please take out the battery and place the meter in
the allocated potable bag and store in cool and dry place.
Please keep the device surface cleaning. Wet soft cloth is
applied to clean dust, but erosion liquid is never allowed to
