BASIC MEASUREMENT
- Place the device on a surface and roll it from Point A to Point B. The measurement data will be displayed on the screen in real time.
- During the measurement, the LED indicator light will flash. When measurement stops, the light will remain on.
- In the default measurement mode, data “X” is the distance from Point A to Point B, where both ends of A and B are unobstructed. See diagram below
CONTINUOUS MEASUREMENT
After the screen data is kept for 30 seconds, the current measured data is cleared to zero, and the measurement can be made again. At this time, the data in the secondary area (top right of the screen) is the historical accumulative data, and the data in the main area (center of screen) is the current single measurement data
DATA ZEROING
Short press the center key for 1 second to clear the current measurement data from the screen. The measured data will be automatically stored inside.
MEASUREMENT HISTORY

From the main page mode, press the LEFT key to change measurement modes. The functions are as follows:
- No obstruction on either the left or right side. Data is the actual rotation distance of the roller.
- Left and right sides are obstructed (such as in a window frame). In this mode, the device automatically takes the full body length into account.
- Left side is obstructed. In this mode, the device automatically takes HALF the body length into account.
- Right side is obstructed. In this mode, the device automatically takes HALF the body length into account.
- This measurement mode measures the circumference of a cylindrical object and automatically calculates the diameter of this object.
