NI 9219 Half Bridge.

[stevem80]

Does the unit have internal half bridge completion resistors?  The manual says the measurement is made wrt EXC-, which is essentially a voltage divider meassurment, yet this link http://digital.ni.com/public.nsf/allkb/3F3165FE0709B8B38625733E007D7C55 says that it has internal bridge completion resistors.  The input signal range of 500mV/V also suggests that it is just a voltage divider measurement.

Hi stevem80,

Sometimes the amount of documentation we have can get confusing!  Yes, the NI-9219 has built-in bridge completion resistors for half-bridge configurations.  If you have any other questions about it please let us know!
