The following check verifies the SLAVE voltage regulation performance.
1. Set the power supply to the INDEP operating mode by disengaging both
TRACKING mode switches (both switches out).
2. Set up the digital multimeter to measure 30 VDC.
3. Connect the digital multimeter and load resistors to the + and – terminals of
the SLAVE output as shown in Figure 4. See Table 9 for the appropriate load
resistor values.
4. Verify that you can adjust the power supply from 0 to 30 V.
The following check verifies the 5 V fixed voltage regulation performance.
1. Set up the digital multimeter to measure 5 VDC.
2. Connect the digital multimeter and load resistors to the 5V FIXED 3A
terminals. Use the test setup illustrated in Figure 4. See Table 9 for the
appropriate load resistor values.
3. Verify that the power supply maintains an output of 5 V,
±0.25 V
