Long press in boot mode button, until the screen displaying press again when blinking Press fourth until to the screen displaying CRL.O press again Button into add subtract range with-7-7mm as adjustment, press again button Save settings when the calibration is completed.

Battery level indication

While all the segment code inthe battery column are all displayed, It means that the battery level shall be at the fulfilled status. While the displayed segment code is quite less, it refers to the relative lower battery level; while the empty battery column is displayed, the new battery should be used for replacing the old one inside the device.

Clear-off function

short Press on button,the last measurement will be canceled. While using the same function or single measurement to the area or volume etc), the clear-off button can be used to eliminate last measuring operation and arrange the measurement once again.

Signal strength indication

While all the segment code of signal are displayed, it means that there shall be the stronger echo signal strength of measurement; while less segment code was displayed, it shall mean the relatively reduced echo signal strength of measurement.

V. Measurement Single measurement

while the laser is off, press button shortly for opening the laser, and the laser icon on the screen will be flashing, with short press button again itshall start measurement. The device will display the measurement result automatically.

Continuous measurement

With laser on, long press on button for about2 seconds itshall start the continuous measurement.Press this button once more to stop continuous measurement.
While performing continuous measurement, the main displaying area will showthe real­ time measurement value, and the maxormin value during the measuring process shall be shown in the supplementary displaying area accordingly. Use the button to select MAXorMIN

VI. Functions Area measurement

Press button shortly until was shown on the screen. To press button to finish the measurement on the first edge, then to press button againto finish the measurement on the second edge and the device will perform the area calculation automatically, and the result will be shown inthe main displaying area.
