± (% output + offset)
Activation time

< 0.5% + 0.5 V
< 1.5 msec, OVP ¥3 V/< 10 msec, OVP < 3 V
1. Accuracy specications are valid after a 1-hour warm-up with no load and calibration at 25 ºC.
2. Meter accuracy specication is at minimum 10 mV decimal limited by front panel resolution.
3. Maximum time required for the output voltage to change from 1% to 99% or vice versa following the receipt of VOLTage or APPLy command via direct GPIB
or RS-232 interface.
4. Average time for output to start and drop after an OVP condition occurred.
