Asterion DC Series Programming
Ramp V Example 2
9.14.5
Program a unit with no load at the output, to ramp its output voltage from 5 VDC to
25 VDC in 30 seconds upon the trigger command.
// Use SYST:ERR? after each command to verify no programming errors.
// turn on the unit.

Power On INIT Example
9.14.6
Program a unit to power-on and initialize to 2 VDC @ 1A with an overvoltage protection
level of 3 VDC. Verify proper power-on initialization.
// Use SYST:ERR? after each command to verify no programming errors.
// turn on the unit.
