5.0 ENERGY TESTING - SET-UP
5.1. The AC line cord of the Model 4431 is a standard IEC cord with North American grounded plug. It
should be plugged into a grounded outlet. For non-North American locations, a line cord having the
correct mains plug can be obtained from a local computer or electronics store. Otherwise, cut off the
plug and install the appropriate plug for the location.

5.2 Connect the BNC connector from the M o d e l 4431 Discharge Unit into CH-1 of the oscilloscope.
The 50 Ohm Terminator provided must be used in order to match the 50 Ohm output impedance of the
CT-1 to the 1 MegOhm impedance of the scope.
5.3 Turn on the computer and verify you are using Windows 10. If you purchased the system and
computer from ETS, the software has already been loaded. Verify that there is an ETS4431 Test
Manager icon on the screen, and there is a C:\ETS\ folder on the hard drive. If not, see Appendix C in
this manual for the setup procedure.
If using computer control, plug the following connections into the computer after the computer is on
and finished booting.
Connect the 25 pin-to-9-pin cable to the 9-pin-to-USB adapter. Connect the 25-pin end of this
cable to the DB25 connector on the rear of the Model 4431. Connect the USB end of this cable
to the 1
st
computer USB port.
Connect the USB-to-USB cable from the oscilloscope to the 2
nd
USB port on the computer.
If a printer is used, connect it to the 3
rd
USB port on the computer.
In case of miscommunication with the computer, unplug and re-plug the USB connector and try
again. Also see Appendix B for USB information.
5.4 If the red jumpers are present, confirm that they are located on the sides of the capacitive
sensor are plugged in the front (“nJ”) position. This programs the capacitive sensor for energy
measurements.
5.5 If using the Foot Switch, then with the Model 4431 Discharge Unit powered OFF, plug the phono
plug from Foot Switch into the REMOTE DISCHARGE jack on the rear panel of the unit.
