Load Transient Recovery Time. Specified for CV operation only; load transient recovery time is the time for the output
voltage to return to within a specified band around its set voltage following a step change in load.
Proceed as follows:
a. Connect the test equipment as shown in Figure 2-3. Operate the load in constant-current mode and set for minimum
current.
b. Turn the unit's power on, and turn up current setting to full output.
c. Turn up output voltage to:
6.70Vdc (6023A)
20.0Vdc (6028A)
as read on the digital voltmeter.
d. Set the load to vary the load current between:
27 and 30Adc (6023A)
9 and 10Adc (6028A)
at a 30Hz rate.
e. Set the oscilloscope for ac coupling, internal sync and lock on either the positive or negative load transient.
f. Adjust the oscilloscope to display transients as in Figure 2-7.
g. Check that the pulse width of the transient pulse is no more than:
50mV (6023A)
75mV (6028A)
