I have a NI 6014 board connected to a AMD Athlon XP 2700, 256 mb ram, asus motherboard.
The board return a incorrect reading when i try to read a dc signal from AO pin, in measurement & automation explorer software. The setting are following:
reading: channel number 1
input: NRSE
rate 1000 hz
mode: everything
Out: DC signal connected to channel 1. Value: 5 Volts, for example.
Pin 22 (AO0) connected to 33 (AI1) and Pin 55 (AOGND) connected to pin 32 (AIGND)
Signal characteristics:
The signal acquired shows a typical signoidal oscillation range 4.3 to 4.8 volts. Moreover there is a hysteresis to get the maximum value, mainly on differential input.
The problem is the same when the signal is acquired by softaware (visual basic program).
I don´t tested in NIDAQ tradictional software.
Do you have any ideia about this problem?
Tank you.
