Note
Before using any measurement equipment, it is important that you thoroughly
understand the safety instructions for that product. The beginning of Chapter 2, NI 4050
Operation, covers the safety guidelines for your NI 4050.
Cable and Probes
The NI 4050 instrument kit contains the NI 4050 accessory cable that
connects the NI 4050 to a pair of test probes with shrouded banana plugs,
which are also included in the kit. Both the NI 4050 accessory cable and the
test probes meet international safety requirements including UL 3111 and
IEC 1010-1 for the full ranges of applications supported by the NI 4050.
Before using any probes or accessories not supplied by National
Instruments, ensure that they meet applicable safety requirements for the
signal levels you may encounter.
To use the NI 4050 accessory cable and probes with the NI 4050, first
connect the cable to the card as shown in Figure 1-1. The accessory cable
connector is polarized so that it cannot be plugged in incorrectly.
