When a Source Bypass is enabled and the External or Trigger Link arm control source is
selected, operation will loop around the appropriate control source on the initial pass through
that layer. Note that the Source Bypass for the scan and measure layers also loops around the
Delay.
If programmed for another pass through the specified layer (count >1), the bypass loop will not
be in effect even though it will still be enabled. The bypass loop will be in effect if operation
first goes back into the previous layer (or idle).
Enabling the Source Bypass for the arm and scan layers also enables their Output Triggers.
When operation leaves the arm or scan layer, the appropriate output trigger pulse will occur. If
the Trigger Link (TLINk) control source is selected, the output trigger will be available on the
programmed Trigger Link output line. For all other control source selections, the output trigger
pulse will be available at the METER COMPLETE Output connector. The Output Trigger in
these two layers is disabled when the Source Bypass is disabled.
The Output Trigger in the measure layer is always enabled and occurs after the Device Action.
With ACCeptor selected, the bypass is disabled, This simply means that operation will not pro-
ceed through the specified layer until the appropriate event occurs.
