Sequoia / Tahoe Series User Manual California Instruments
M447352-01 REV-A 83
WARNING!
When performing the Sequoia unit in eLoad operating mode make sure that the
UUT voltage range is compatible with the Sequoia Voltage range and operate the
Sequoia unit with the appropriate voltage range to protect against hazardous
voltages that are present on the input and output.
4. Synchronize the Sequoia with the UUT output by pressing the Sync button from the front panel
dashboard screen, refer to the below image.
5. The sync button will be highlighted once the synchronization has happened or else an error
message will be displayed with the text “Sync Settings Error” If the error occurs, verify the
programmed sync voltage is matching with the output voltage of the UUT.
6. Set the required programming parameters through the front panel dashboard screen and enable
the output of the sequoia.
4.1.3.5 Basic Functional Test of eLoad – Current Programming Mode
.
WARNING!
When performing the functional tests, exercise appropriate care to protect
against hazardous voltages that are present on the input and output.
A basic functional test of the Sequoia in eLoad Mode could be performed with the following steps:
1. Connect a UUT output to the Sequoia output connector.
2. Connect a DVM to the Sequoia output connector. Recommended equipment: DVM, Keysight
34461A.
3. With the AC mains verified as being off, make the AC input voltage connections to the Sequoia
unit input connector.
4. Turn on the AC mains, and then turn on the POWER switch on the Sequoia front panel.
5. Verify that the front panel display lights up. After several seconds the display should show the
DASHBOARD Screen Top-Level Menu or the Default screen; refer to Section 5.6 for the
description of menus.
6. Switch on the UUT and set voltage 150V(RMS), frequency 60Hz.
7. Set the sync voltage, sync frequency, and sync phase to the Sequoia and perform synchronization
(refer to section 4.1.3.1).
