Transient response
time
<50 μs for the output to recover to within 15 mV following a change in the output
current from full load to half load or vice versa.
Settling time <90 ms for the output voltage to change from 1% to 99% or vice versa following the
receipt of the VOLTage or APPLy command via direct GPIB or RS-232 interface.

(Average time for the
output to start to drop
after the OVP condition
occurs)
<1.5 msec when the trip voltage is equal or greater than 3 V
<10 msec when the trip voltage is less than 3 V
[1] Accuracy specifications after a 1-hour warm-up period with no load and calibration at 25 °C.
[2] Meter accuracy specification at a minimum of 10 mV decimal limited by the front panel resolution.
