Figure 1-1. Installing the NI 4050 and Cables
The test probes connect to the NI 4050 accessory cable via shrouded
banana jacks. The shrouds around the banana jacks prevent you from
contacting potentially hazardous voltages connected to the test probes.
You can also connect the cable to standard, unshrouded banana jack probes
or accessories; however, use unshrouded probes or accessories only when
the voltages are less than 30 V
rms
or 42 V
pk-to-pk
.
Caution To prevent possible safety hazards, the maximum voltage between either of the
inputs and the ground of the computer should never exceed ±250 VDC or 250 V
rms
