Source delay
NOTE For the Model 2430 Pulse Mode, source delay is not used. The following
information assumes that the Model 2430 is in the DC Mode of operation
(“Vpls” or “Ipls” displayed). To select the DC Mode, press CONFIG and
then SOURCE V or I, select SHAPE from the available menu items, and
then select DC.
The source delay options are used to set the settling time for the source. This
source delay is the delay phase of the Source-Delay-Measure (SDM) cycle. See
Section 6. The auto delay option is used to automatically set the delay. The delay
period is range dependent (Table 3-4).
The delay option is used to manually set the delay from 000.00000 seconds to
9999.99900 seconds. Manually setting the delay disables auto delay.

1. Press CONFIG then SOURCE V.
2. Select DELAY from the displayed choices, then press ENTER.
3. Enter the desired DELAY value, then press ENTER.

To set the auto source delay state from the front panel:
1. Press CONFIG then SOURCE V.

3. Select ENABLE or DISABLE as desired, then press ENTER.
