CC Mode PARD Test
CC mode PARD (periodic and random deviations) is specified as the rms input current in a frequency range 20Hz to
10Mhz. This test checks CC Mode PARD.
a. Connect the Electronic Load, power supply (Agilent 6032A or equivalent, DMM, and current probe as shown in Figure
2-3. Set power supply for 10V and >10A.
b. Turn the load's ac power off, then on.
c. Press CURR 1 0 Enter
.
d. DMM reading should be less than:
6060B: 4mA rms
6063B: 1mA rms.
Figure 2-3. Test Setup C
CC Mode Power Limit
This test verifies that the Electronic Load's power limit circuit is operating properly. If the results specified in steps d
through i are not obtained, troubleshoot the circuits as described in "Overpower Circuits Troubleshooting" in Chapter 3.
If the overpower circuit does not turn the load off within three minutes after performing step d, stop the
tests and troubleshoot the overpower circuits.
a. Connect the Electronic Load and the power source as shown in Figure 2-2.
b. Turn on the Electronic Load and run for approximately five minutes with no power being dissipated (no input power).
c. Then Press MODE VOLT Enter , then
6060B:
VOLT 2 0 Enter
.
6063B:
VOLT 3 5 Enter
.
a. Turn on and set the power supply for:
6060B: 34volts and 18mps.
6063B: 45volts and 13mps.
The Electronic Load's front panel should indicate approximately:
6060B: 33 volts and between 13 and 17 amps.
6063B: 45 volts and between 7.2 and 10.9 amps.
The front panel Prot annunciator should also be on.
