NOTE: Depending on the value of high voltage, the over current limit may or may
not be exceeded even when the load is shorted.
If the Over Current LED illuminates when the PVX-4140 B is in Auto Reset mode
(see Section 4.7), the pulse output will be inhibited for 6 to 7 milliseconds. If Auto
Reset is not enabled, the instrument must be manually reset. (A manual reset is
accomplished by pressing the Enable button twice: Once to reset the fault, and the
second time to enable the output. The instrument may also be reset via the remote
reset function. See section 4.7.)
If the Over Current LED illuminates continuously, the cause of the over current
fault should be corrected before attempting to operate the instrument.
4.6.6 Control Error LED
To permit burst mode operation, the Control Error LED is not used in this
instrument model.
4.6.7 Current Monitor
The Current Monitor BNC connector provides a 10 A per V scaled version of the
output current for display on an oscilloscope. The scope input impedance should
be 50
Ω
.
4.6.8 Voltage Monitor
The Voltage Monitor BNC connector provides a 1 V per 1000 V scaled version of
the output pulse voltage for display on an oscilloscope. The scope input
impedance should be 1 M
Ω
