11. Tapping the OUTPUT switch button would turn on the OUTPUT LED when the output is on.
12. Switch on the Output and operate in the desired condition. (Can Load up to 100% of the rated power)
13. Verify that the front panel power measurement is negative or observe the voltage and current
waveforms in the DSO and those will be 180 deg phase shifted. Verify that the front panel power
measurement is negative or observe the voltage and current waveforms in the DSO and those will be
180 deg phase shifted.
4.1.3 eLoad Mode
NOTE: This mode applies only to the SEQUOIA series. TAHOE series does not support this mode.
Energy flow is from UUT to facility AC input through SEQUOIA as shown in Figure 4-3. In Electronic load
mode, SEQUOIA regulates the RMS current set by the user and works as the load for UUT.
In this operating mode, the user could program the load to be applied to UUT using the following
programming types.
Current Programming: The user can program the RMS current, and phase angle (between voltage and
current) required as the load for the UUT.
Active and Reactive Power programming: The user can program the Active power and the Reactive
Power required as the load for the UUT.
Parallel RLC programming: The user can program the Resistance, Inductance and Capacitance required
as the load for the UUT.
