Unless already at -30 the spindle will first travel to that point. The stand will then move to +1000 from tared zero,
followed by a final movement back to -30 .

Data capture within VectorPro™
VectorPro manages the test configuration to control test stand operation, ensuring the speed and test orientation
match your requirements. VectorPro also provides real time visualisation of results during testing. Data is stored
with VectorPro's database for analysis, and can be exported to most popular formats using the built-in reporting
templates, such as PDF, XLSX, CSV, TXT, HTML, and many more.
At the end of a test, or in a stopped condition, you may need to move the crosshead to clear a sample, or the
drive spindle to remove residual torque.
Never restart a test from a stopped condition with a residual torque, and always Reset the gauge before a
subsequent test.
For more information please refer to the

Half Cycle

If the test stand is switched off or loses power during an active test, the drive spindle will stop.
A half-cycle test is to an angular displacement relative to tared zero. A cycle starts when the crosshead is at the
first displacement position and ends back at the second position.

Unless already at -90 from tared zero, the spindle will travel to that point and then move to +180from tared
zero, and stop.

Operation sequence and move to start
Operations, such as the half cycle consist of two datum points, a clockwise angle and anticlockwise angle.
For operations with the primary movement being clockwise, the following is true:
· The 'Anticlockwise Angle' is the start position for the test and the 'Clockwise Angle' is the finishing
position.
For operations with the primary movement being anticlockwise, the following is true:
The 'Clockwise Angle' is the start position for the test and the 'Anticlockwise Angle' is the finishing position.
Options Options
Choose whether the test direction is clockwise or anticlockwise
Select if the test moves to the start position first
