Use the ETX Inverter Production Test System Maintenance Software to do the following:

• Check whether the system contains correct components
• Interactively reset, self-test, and self-calibrate components that support those operations
• Check continuity between the internal system components and the mass interconnect

To check continuity, you also need the field diagnostic tester (FDT), a hardware accessory for the ETX Inverter Production Test System.

NI-Pulser is an NI instrument driver that lets you control the pulser, which is composed of several individual instruments, interconnecting cables, and interposers within ETX Inverter Production Test System. NI-Pulser also supports contactless current sensors inside the test system and/or within fixtures attached to the test system. NI-Pulser includes .NET API and example programs in C#.

NI-PowerSignalsDAQ is an NI instrument driver that lets you control the Power Signals DAQ, which is composed of several individual instruments, interconnecting cables, and interposers within ETX Inverter Production Test System. This instrument driver also supports contactless current sensors inside the test system and/or within fixtures attached to the Test System. NI-PowerSignalsDAQ includes .NET API and example programs in C#.

The NI-PowerSignalsDAQ API relies on the RM-26999 and supporting hardware to take measurements from signals located on J15 and J18 of the mass interconnect.

• Current measurements are taken using a current transducer. The signal level is routed back to the RM-26999 through the mass interconnect on J18.
• Voltage measurements are taken on J15 of the mass interconnect.
