VOLTECH AT3600 USER MANUAL DESCRIPTION OF THE FIXTURE SYSTEM
4. BEZEL
This provides an accurate location for the probe housing box and the test piece
interface plate. The design also includes support areas for the rear of the guides.
5. GUIDES
The guides help to locate the test piece into the fixture quickly and accurately.
They are adjustable to suit the test piece plan size and can be stacked or reversed if
required.
The guides are capable of having sections cut off to enable them to be used down to
small footprints. Four pairs are shown in the sketch.
6. CLAMP
A clamping mechanism may be purchased to hold the test piece in place for testing.
The clamp head has a sliding guide which allows the vertical clamping rod to move
horizontally relative to the clamp head. This minimises the possibility of side
movement to the test piece during the clamping action.
The clamp head is also designed to accommodate springs of force ratings of
2.9N/mm, 4.5N/mm and 5.4N/mm to allow for the differing types of probes used for
wound component connections.
.
7. HEIGHT BLOCKS
Height adjustment blocks are capable of being stacked in order to clamp a UUT of up
to 70mm in height in 10mm steps.
8. TOOLING
To enable the probe housing box and the test piece interface plate be drilled to the
accuracy required, drilling templates are available in the following grid pitches:
1.27mm
2.00mm
2.50mm
2.54mm
3.81mm
