4.1.2 System Grounds and IsolationThere are three scenarios possible when connecting your signal source to your PCI-DAS1000 board. 1. The PCI-DAS1000

WARNINGIf either the AC or DC voltage is greater than 10 volts, do not connect the PCI-DAS1000 to this signalsource. You are beyond the boards usable

Relying on the earth prong of a 120VAC for signal ground connections is not advised.. Differentground plugs may have large and potentially even danger

4.2.1 Common Ground / Single-Ended InputsSingle-ended is the recommended configuration for common ground connections. However, if some of your inputs

4.2.4 Common Mode Voltage < +/-10V / Differential InputsSystems with varying ground potentials should always be monitored in the differential mode.

4.2.6 Isolated Grounds / Single-Ended InputsSingle-ended inputs can be used to monitor isolated inputs, though the use of the differential mode will i
