Battery Charging
It has a built in Lithium Ion rechargeable battery. A standard charger is supplied that the
input voltage is 110V to 240V AC, 50/60Hz, and the output is 5V DC, 500mA. The
charger operating procedure is list below:
1) Plug the Charger into AC socket, the RED indicator on the charger should turned
ON,
2) Plug the USB charging cable to the Charger,
3) Insert the other end of the USB cable to the unit,
4) The battery icon on the LCD blinks to indicate charging in process. Upon charging
complete, the icon stops blinking.
5) The charging time is approx. 3 hours.
The unit could also be charged by connecting the USB cable to the unit and a computer’s
USB port. This has the same effect when charging the unit with the provided adaptor.
Note: When the unit is turned OFF, and plug in the USB charge cable, the LCD will no
show anything, it is NORMAL. Once the unit is turned ON, the battery icon should flash
indicating the unit is in charging mode.

LEVEL CAL.
Calibration
Calibrate the unit, once you found that there is accuracy drift on the unit. You can verify
the accuracy at below step:
At Step1, you measured X and Y value, X1 and Y1
At Step2, you measured X2 and Y2, in theory X1=-X2, Y1=-Y2.
If the error is too large, you can enter calibration mode to eliminate the error
Accuracy drift is causing by large ambient temperature change (5 to 10 Degree Celsius)
or the unit has been dropped.
Calibration Procedure:
Step 1: Press and hold the “Angle/Set” key enter Menu mode. Select “LEVEL CAL.”
mode, press “SET”. Place the unit on a flat table (no need perfect level table)
LCD display “DUAL AXIS CALIBRATION”, press “SET” and buzzer will beep; wait until
the beep sound stop. While the buzzer is beeping keep the unit stable.

Step 2: Then rotate the unit 180 degree with the other side against the same place.
Press the Set button again and wait for the beep finished.
Step 3: LCD display “SINGLE AXIS CALIBRATION”. Place the unit horizontal like the
picture “STEP 3” and then press “SET”, wait until the beep sound stop.
Step 4: Then rotate the unit 180 degree at the same place. Press the “ZERO” button
again and wait for the beep finished.

Step 5: LCD display “SINGLE AXIS CALIBRATION”, mention that the ON/OFF Key at
upper side, hold on a flat wall. And then press “SET” Key. Wait for the “Beep” sound stop.
Step 6: Then rotate the unit 180 degree with the other side against the same place of
wall (ON/OFF Key at upper side). Press the Set button again and wait for the beep
finished. Now, the LCD should go back to the selection menu. The calibration is done, by
selecting “Back” to go back for normal operation
GYRO ANY ANGLE measurement:
Any angle measurement is using gyro technique.
You can measure the angle between two faces, not only in earth gravity direction.
1) Press Angle key at the first face, and then rotate slowly and must keep the rotation
axis to another testing face
2) It will then show the angle once you do not move the unit.
