2013 Aug 1 SINGLE DUAL.X DUAL.Y RANGE Vertical / Single axis mode alarming angle (Degree) Horizontal/ Dual axis mode X axis alarming angle (Degree) Horizontal/ Dual axis mode Y axis alarming angle (Degree) The range (Degree)that will trigger the audible alarming For example: SINGLE. set to 20.00 RANGE set to 01.00 While the unit is in +19° to +21°or -19 ° to -21°, the unit will alarm ACTIVE IN or OUT to set the alarm will alarm in of range or out of range

Calibration

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

2013 Aug 1 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 “SET” or “ANGLE” 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.

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 “CALIBRATE VERTICAL PRESS SET”, 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

ANY ANGLE measurement: *DXL360S/C only 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 not move the unit. The rotation axis:
