Range: Uniaxial 4 x 90 degree/Biaxial 40 degree Resolving power: 0.1 degree Accuracy: Uniaxial 0.2 degree/Biaxial 0.3 degree Repeatablitiy: 0.1 degree Power supply: 3.7V lithium battery Magnet: Only the top and button surface has the magnet Wireless Data transmission function: Pairing: When the tilt box and the receiving device with Bluetooth device (computer, cell phone, etc.) are used together for the first time, the two need to pairing operation, the specific operation method is: open the Bluetooth search function of the receiving device (computer, cell phone, etc.), while long press the wireless transmission key on the tilt box, until the"on the LCD of the tilt box begins to flash Indicates that the caliper enters the searched mode, release the wireless transmission key, wait until the receiving device searches for the device with the name K-XXXXXXxXxx, then click connect. After successful connection, "on the LCD of the tilt box will remain on. Data tasmissin (tor example, mobile phones and computers): After the connection is successtul, open the ofie software and keep the interface active. Press the wireless tansnission key briefly, and the tit box can send data 10 the rceving devices Main display: 1. For uniaxial measurement, the main display screen only displays x- -axis data 2. For biaxial measurement, the main display screen displays X-axis and Y-axis data at the same time. Colour:black Material:plastic Package Contents: 2 x Level Inclinometer Dual
