3.1.15 Dual Robot Calibration and Joint calibration. 
 
Dual Robot Calibration kit (Part no: 185500) 
 
Dual Robot Calibration is a calibration that calibrates the robot in the full work space. All robots are Dual 
Robot Calibrated when they are produced.  
If a joint has been replaced on a calibrated robot the calibration is not correct anymore. 
 
There are 2 options: 
-  Performing a Dual Robot Calibration after replacement of a joint will let the robot continue in the 
production line without modifying waypoints in the robot program. To perform a Dual Robot 
Calibration you need: 2 robots, calibration Horse and calibration tool connector.

-  Joint calibration described in this section: After replacing a joint a zero position of the joint can be 
adjusted but the calibration level form the Dual Robot Calibration cannot be achieved. Adjustments 
of waypoints in the program should be expected.
