Overview:The sensors of forearm and rear arm have been calibrated before sending out. But if you need calibrate again, please review following steps for reference:
Step 1: Remove Angle SensorsRemove sensors of forearm and rear arm with hexagonal wrench and put them down the table horizontally, as shown in figure 1;
Figure 1 angle sensors
Step 2: Access to Calibration ModeConnect Dobot with PC, and open DobotTerminal under the file of DobotTools, then set baud rate to 9600(If it is the version of V1.0, baud rate is 25600), now it can be connected successfully, as shown in figure 2.
Figure 2 baud rate setting
Step 3: Access to Calibration ModeFirstly hold down the button Sensor Calibration on the controller, then press the button Reset to restart control panel, keep on holding Sensor Calibration for 2 seconds and then loosen it, now there is a warning that remind you to "start calibrating", as shown in figure 4.

Step 4: Start Calibrating1.Keep sensors of forearm and rear arm flat with level 0°; 2.Single click Sensor Calibration (calibration of rear arm), at the moment, serial port will hint that calibration compensation of “Long arm angle” and measurement error of "Long arm angle new"; If got successful calibration and proper error, it will updates calibration success, as shown in figure 5.

4.If there appears "failed, need to be re-calibrated" shown in figure 7, please make sure put down sensors horizontally and then return the steps 3~5;
Figure 7 message of calibration error
5.Restart circuit board after calibrating.
Notice: 1.Make sure enough key-hold time for about 2 seconds so that can be detected. 2.Calibration message will be kept in EEPROM and take effect in the next measurement.
