not stable output values

1) dasylab 9.0

2)personal daq/3000 series 16 bit/1-mhz usb data aquisition system

 

We take measurements in volts and with an equation in input module we take kg

the values appear unstable continiously in the displays windows.

How we can make the values stable ?

This is a normal effect with data acquisition system especially block based.  you have three options

- reduce the sample rate to a logical frequency.  No need to use 10Khz when you only need 10Hz

- filter the signal before it goes into the display.  This is what I usually do

- use the average to reduce the points
