Delay Menu (only available when trigger mode is set to Threshold)

When using threshold triggering for load capture, the Delay menu provides a means
of manually controlling the duration of the stroke capture. Load capture begins
when the load crosses the threshold value and ends after the fixed delay time. This
is advantageous for applications that normally see the load drop below and then rise
above the threshold value more than once within a single press stroke (i.e. a double
hit).
In this example of a double-hit, the load rises above the
threshold value, peaks, and then drops below the
threshold to end Hit #1. However, the load then rises
slightly above threshold once again before finally
dropping once more (Hit #2). This behavior will
commonly cause the peak tonnage to update twice,
which prevents the monitor from displaying the true
peak at the end of the stroke. This can be remedied by
entering a delay value (1 second in this example),
which prevents the stroke from ending too early.
To change the Delay Value
1) Push to enter change mode. Current setting is then selected.
2) Push or to change the setting, or
Push or to change in a larger increment.
3) Push to accept the change, or push to cancel the change.
Notes:

You can choose any time delay value from 0 seconds up to 9.999 seconds.

Setting the time delay value to zero disables the delay feature. The load capture will
end when the load drops below the threshold value.
