Narrative:
Flying the karoo arrival into rdu; I asked the first officer to select the lowest altitude on the arrival which was 6;000 MSL. I pulled up the direct/intercept screen and looked at the vsi rates required to meet all the restrictions and I selected a vsi rate of 900 FPM which I thought would meet all the restrictions. I must have not thought it out correctly because we descended below the floor of one of the restrictions by 500 ft. I immediately noticed and entered a climb back up to the appropriate altitude. ATC said nothing to us and we continued the flight without further incident.this happened because I set an incorrect descent rate to meet all the restrictions. Also; I have learned my lesson that I should always set the individual floors of the arrivals one by one instead of just asking for the lowest altitude of the arrival to be set. If I had asked the first officer to set the first floor; then the second; then the third and so forth this problem would never have happened. In the future I will do it that way.
