Delay FOLDBACK

You can specify a time for the FOLDBACK delay, which can make the

instrument ignore the instantaneous change of the operating mode in the

specified delay interval. In most cases, this instantaneous situation is not

considered as a switching state, and there is no need to trigger the foldback

function and disable Output. Once the FOLDBACK delay time is exceeded, the

output is turned off.
