dc Floating Voltage: All outputs can be floated up to ±240 Vdc
from chassis ground
Remote Sensing: Up to 10 V drop per load lead. The drop in the load
leads is subtracted from the voltage available for the load.
Command Processing Time: 7 ms typical with front-panel
display disabled
Input Power: 550 W max., 720 VA max.
GPIB Interface Capabilities: SH1, AH1, T6, L4, SR1, RL1, PP1, DC1,
DT0, C0, E1.
Regulatory Compliance: Listed to UL 1244; conforms to IEC 61010-1.
