14. Results - changes how the data will be displayed on the LCD graphic
display after a test is completed. There are three selections available (LAST,
ALL, P/F). The LAST setting displays the last step within the program
sequence. The ALL setting will display the results of every step within the test
sequence in a list format. The P/F, or PASS/FAIL, will display banner text of
PASS or FAIL depending on the results of the test.
15. OC Fold - reduces the voltage, or folds the voltage back, in a linear
fashion while maintaining a constant current to help run inductive loads.
16. Transient (MANUAL Mode) - allows the operator to perform transient
testing while in Manual Mode. Transient is only selectable when the source is
configured for AC output.
17. Lock – allows the operator to lock out the buttons and rotary knob on the
front panel. The level of security is determined by the Mem Lock function.
18. Mem Lock – allows the operator to restrict access to memory and step
locations. Lock must be set to ON in order for Mem Lock to function.
19. Volt Sense - configures the for internal or external voltage sensing. If
internal is selected, the instrument will measure the output voltage at the
output relay. If external is selected, the user must connect sensing wires from
the Ls and Ns terminals located on rear panel output terminal block to the
DUT. Using external sense will provide a more accurate measurement when a
large voltage drop occurs over the output wires.
20. Sync Signal - provides an output signal that may be used to trigger an
oscilloscope. The output signal is provided on the rear panel via the BNC
connector labeled Sync. There are 4 Sync signal options: 1) OFF: the Sync
output is disabled, 2) ON: the Sync signal is active during testing, 3) EVENT:
the Sync signal is active when the output voltage changes, 4) FREQ: the
Sync signal provides a square wave output at the same frequency as the
instrument’
s output voltage.
21. Function (Option 08) - configures instruments for either Parallel, 1 3W
or 3 4W operation when multiple AC power sources are interconnected.
Parallel operation allows the operator to increase the total output current by
connecting 2 or 3 sources in parallel. 1 3W operation allows the operator to
increase the output voltage to 600 VAC using 2 sources outputting voltage at
180 degrees. 3 4W operation allows the operator to configure the
instruments for 3 operation.
