Using Angle Beam Probes

When connecting an angle beam probe to the instrument, adjustments must be made for probe characteristics as well as test piece geometry. 
These adjustments include:

•

Probe angle

•

Probe X value = the distance from the probe Beam Index Point (BIP) to the front edge of its wedge

•

Test piece thickness

•

O-Diameter

3.2.1

Setting the Angle Beam Probe Parameters

To configure the instrument for an angle-beam probe, follow this procedure:

1.

In the 

SETUP

 menu, activate the 

EVAL

 submenu using the joystick (

).

2.

Use the joystick (

) to select the function titled 

PROBE ANGLE

. Input the angle for the installed probe. Surface evaluation is 

performed by installing the correct probe/wedge and setting this value to > 89°.

Note:

This function has both coarse and fine adjustment modes. Coarse adjustments are made with the function toggle, while fine 
adjustments are made with the joystick.
