Stress Stop Function at Abnormal Status
On the STRESS: STRESS SETUP screen, you can select whether the stress stops or
continues when an abnormal status occurs. When an 4155B/4156B is stopped by the
stress stop function, a message is displayed in the message display area.
The stress stop function is not effective until the stress has been forced for 10
seconds. For example, if
STOP AT ANY ABNORM
or
STOP AT COMPLIANCE
is
selected and abnormal status occurs after forcing stress for 5 seconds, the stop
function does
not stop stress until stress is forced for 10 seconds.

STRESS SETUP screen:
• STRESS Status = CONT AT ANY
