Creating Lookup table in Labview 7.1

[Imti]

well my problem is... i have eperimental data which says

  voltage             distance

  4 to 4.2 mv        6cm

  4.3to 4.5mv       5 cm

  4.6 to 4.8mv      4 cm

so on... there should be a contron which takes my input voltage and give corresponding distance.

i.e. if my input is 4.4 mv the output should be displayed as 5 cm.....

i thought i would implement this using lookup tables, but i m not getting the hang of it....

so could u please suggest me what to do?

I am baffled why the previous posting is not working for you unless you are still using the first quicky VI I posted as a fast example.

Try this zip. In it you will find updates of all of the above VI's.

I have adapted it explicitly for your data. Please watch it run in execution highlighting mode to learn how it works.

What you should see is

1) First the translation table is loaded with your data.

2) A loop iterates and generates random values between 4. and 4.8 mV.

3) Each simulated reading is translated using your table.

4) The raw mV and translated cm values are plotted as two seperate traces on the chart.
