The new mode of Guzik Test System operation allows for performing tests approximately 20–30% faster. This is an optional purchase component of WITE32, which requires a license.

The two new enhanced performance modes are Immediate Start Mode (Full Revolution) and Immediate Start Mode (Partial Revolution). The following four modes of operation are available in WITE32 version 4.00:

Mode 1: Start on Index (Full Revolution)
Mode 2: Start on Index (Partial Revolution)
Mode 3: Immediate Start (Full Revolution)
Mode 4: Immediate Start (Partial Revolution)

Please refer to the chart below for comparison of the typical production test time for all four modes.
