(1) The current readback accuracy of the 5 mA range is measured in constant voltage mode. (2) From 10% to 90% or from 90% to 10% of total power excursion. Using positive output polarity.
(3) Fall time at full load when output is disabled.
(4) The set voltage will change to 0 V when the power supply output is 30 V.
(5) Time for output voltage to recover within 50 mV for a load change 50-100% of full load. Output speed set to Fast.
(6) Typical time required for output to begin to change following receipt of command data.
(7) Relay off function only supported for CH1.
