is pressed, the unit reset current angle to zero.
Direction of tilt icons, show the tilt angle direction
Dual-Axis Mode. Both the X and Y axis angle will be showed. Dual
axis mode measures inclination up to +-40 degree for each axis
before it automatically switch to single axis mode.
Single Axis Mode. Measure slope up to +-90 degree.
The triangle icon indicates the direction of tilt with respect to the
bottom right corner of the unit.
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.

Calibration
Calibrate the unit, once you found that there is accuracy drift on the unit. You can
verify the accuracy at below step:

2014 Dec 10

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 “Calibration”
mode, press “SET”. Place the unit on a flat table (no need perfect level table)
LCD display “CALIBRATE DUAL AXIS PRESS SET”, 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.
