Half Cycle
If the AFTI is switched off or loses power during an active test in AFTI Control mode, 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.
Within the ‘Edit Test’ display on your test stands front panel there is an option called ‘Move to Start’, setting this
feature to ‘Yes’ means that the stand always moves to the start position.
In some instances, this means the first direction of movement is opposite to the primary test movement. Jog

PIN Code
Within the PIN code menu, it is possible to set a four-digit number that can be used to lock the menu feature of
your Vortex-
dV
. Please note once this has been set you cannot access the menu without the PIN, so it is crucial
that you keep a record of this safe.
If the PIN code has been set and then lost or is unknown, please contact your local agent or
