Strain gauge Measurement

Post by Nick » Sun, 05 Mar 2006 19:28:05


Hello All,
I am using SCXI 1520 using Terminal Block 1314 for Strain Gauge
Measurement.
We have got a Strain Gauge of 120 Ohm with the NI Hardware which was
connected to CH02(One of the 8 channels provided), Now my problem is
that if I connect the Strain Gauge to some other channel(except Channel
2) I am not able to get any readings , and if I reconnect it back to
Channel 2 it gives prorper results.
I have connected the strain Gauge in
a Quarter bridge Configuration(obviously for a Single Strain Gauge) as
per the circuit diagram provided correctly.

I have Pentium -4 , 256MB RAM, Win XP SP2 machine.

Could anybody please try to explain where I am going wrong.

With Regards
Sandeep
