Current set point

Transient List point data entry method.

Transient list points are numbered sequentially from 0 through 99 and executed in this order.
Each list point or list entry has 9 parameters as shown in the table above. To enter list point data,
the keypad must be used. The shuttle knob is used to increment or decrement the list point
sequence number (#). The sequence number can only be increased to the next available empty
(new) list point.

To move to the next or previous parameter, use the UP () or DOWN () cursor keys

It is not necessary to use all list points, only as many needed to accomplish the desired output
sequence.

Setting Data Values

Data values can be set for each point in a list. If all data values in a specific list are going to be
the same value (e.g. the current limit parameter is set to the same value for the entire transient
program), only the first data value for that parameter has to be set. Setting only the first data
point will automatically repeat that value for all subsequent points in the transient list.

Setting Slew Rates

Very often, output changes must be done as fast as the power source can make them. This
means the transient list slew rate is set to its maximum value. If this is the case for all the data
points in the list, it is sufficient to set just the first data point's slew rate for either voltage and/or
current. Setting only the first point of any parameter in the list will automatically cause all points
for that parameter to be set to the same value. This saves a lot of data entry time. The max slew
rate can be set by entering a value of 0. When the enter key is pressed, the value will change to
“MAX”.

If however, one or more data points require a specific slew rate such as needed to do a ramp, all
other points have to be specifically set to their required slew rates, including the maximum slew
rate.

Saving Transient Lists

Once completed, a transient sequence can be saved along with the steady state setup of the
instrument by using the REGISTER, SAVE menu. Registers that may be used for this purpose
are 1 through 15. It is advisable to do so, especially for longer transient lists.
