Ramp the Output

When ramped, the source sweeps up or down in value.
Use the ramp feature to check a switch or alarm, or when
a smooth increase or decrease of the output function is
necessary. The Product can be set to ramp up or down in
engineering units (mV, V, mA, °C, etc.) or % of scale.
While the signal ramps, the output is adjusted 4 times per
second. The size of the steps is bound by the selection of
endpoints and ramp time. For example, if you set the
Product to ramp from 1 mV to 1 V over 10 seconds, the
output is adjusted in approximately 25 mV steps.
The Ramp function continues until you get the selected
limit, or until an optional trip condition is met. The optional
trip detect works as follows: during ramping, the Product
checks for either a 1 V change in dc voltage or a change
in continuity status (Open or Short) from one ¼ second
interval to the subsequent interval.
