Hi Ladies & Gents;

I need a little help. I have a strain gage .vi program but I need to change/add two things:

1) Filter. I need an adjustable filter to filter out low frequency noise.

2) How do I zero out my gages? One gage reads .0012 and the other reads .0004 when nothing is turned on. How di0 I reset/calibrate them to zero?

Program Attached below.

Labview 8.0

Thanks for any help you can provide. I am new to labview, but quickly learning.

1) Look into the function palette-->Signal processing-->Waveform conditionning

2) One of the simple ways would be to acquire the data once before looping and substracting the values in your loop.

Here's a hint. You don't have to loop through an arrray to do simple arithmetic - just use the arithmetic functions they will operate on arrays using a scalar input.
