daqcard 700 read always 9,9658 volts

[wakeup]

I have a  daqcard 700, It always read 9,9658 volts in all channels since several days ago. I measured in the 1 channel it has 1,5 volts before go into the pcmcia, but it always read the same in the 1 channel and in the other channels with no connections. If I remove the cable of data it read the same in all channels too  9,9658 volts

Do you know what could be happening?

Thanks in advance

I have no direct experience with this card but what you are seeing for unconnected channels is normal. Search the forum for 'ghosting' to get an explanation. As far as what you are seeing on ch 1, what you haven't provided is whether you have configured the card for RSE or DIFF and what connections you have used for the signal and reference. There are sections in the manual that explain both.

I have only  connected in RSE to channel 1 1,5 volts, and nothing more connected. And it read 9,9 in all channels.

I think it doen't ghosting because it is a analog and few changeable input.

Thanks

Connect your AI Gnd up. Did you read the manual and the section on how to connect signals up?

I have connected it.

I read it.

It run a week ago, and without changing any connection it started to fail...

I think the card died 😞

Yep-

me thinks you blew the input gain stage.  Be more careful after you get this one repaired

Do they still repair this card?
