#### Probe Head Wrist Angle

The A Angle and B Angle boxes indicate the position of the probe head while sliding the probe configurations in place. In most cases the angle should indicate a straight down position. When calibrating slots holding extensions, the AB angle boxes should be defined prior to calibration. If you try to change the AB angle after the slot has already been calibrated, a warning will appear informing you that recalibration will be needed.

To change the AB angles from the straight down position:

1. Place the cursor in the A Angle box or the B Angle box.

2. Type the desired angle.
