Figure 2-7. Peak-To-Peak Measurement Test Setup, CV PARD Test
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.
Use the equipment setup of Figure 2-5 to display output voltage transients while switching the load between 10% with the
output set at:
60Vdc (6030A)
7Vdc (6031A)
20Vdc (6032A)
200Vdc (6035A)
Proceed as follows:
a. Connect the test equipment as shown in Figure 2-5. Operate the load in constant-current mode and set for minimum
current.
b. Turn the unit's power on, and, using DISPLAY SETTINGS pushbutton switch, turn up current setting to full output.
c. Turn up output voltage to:
60Vdc (6030A)
7Vdc (6031A)
20.0Vdc (6032A)
200Vdc (6035A)
as read on the digital voltmeter.
d. Set the load to vary the load current between:
15.3 and 17Adc (6030A)
108 and 120Adc (6031A)
45 and 50Adc (6032A)
4.5 and 5.0 Adc (6035A)
at a 30Hz rate for the 10% RECOVERY TEST.
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 2-8.
