The NI4050 instrument kit contains the NI 4050 accessory cable that

connects the NI40 50 to a pair of test probes with shrouded banana plugs,

which are also included in the kit. Both the NI4050 accessory cable and the

test probes meet international safety requirements including UL 3111 and

IEC 101 0-1 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 NI4050 accessory cable and probes with the NI 4050, first

connect the cable to the card as shown in Figure1-1. The accessory cable

connector is polarized so that it cannot be plugged in incorrectly.
