Half Cycle 

 

A half-cycle test is to an angular displacement relative to tared zero. 

 

Movement always ends at the angle set in the starting direction, shown in red below. 

 

A half-cycle only starts when the drive spindle is at the furthest displacement position, 
relative to tared zero, from the end position. 

This can appear confusing. The conditions in the shaded rows of the table below provide 
a true half-cycle test. 

Familiarise  yourself  with  why  the  others  effectively  result  in  a  full-cycle  movement.  A 
single cycle test is usually a better choice. Note that row conditions 3 and 4 under a full 
cycle test (any number of counts) will also result in a half-cycle action. 

Half-cycle tests will always end with the display reading the final angle that was set. To 
re-run, the drive spindle must be returned to zero, or the displayed angle tared to zero.
