Please put the sub VI. Thanks.

Calculating wet bulb from dew point and ambient temperature is hard. It requires iterative algorithms. It is easy to calculate RH, absolute humity and enthalpy.
I have attached a paper I find usefull, "Numerical calculations of psychrometric properties on a calculator" by Singh, et al.
If I find an algoritm for wet bulb or figure out how to implement Singh's I will upload my VI.

For calculations with relative humidity the trial version on www.psychrometricchart.net is also very usefull.

Can anyone please help with how we could use lookup tables for calculating dew point temperature or other parameters?
Basically, I want to know how we could use lookup tables.

If you have a lookup able, you don't need to calculate anything, you just need to look up values. Do you also want to interpolate?
What "other parameters" are you interested? You need to be more specific, we cannot read your mind!
What have you tried? Do you have the relevant tables?

A few years back I made an excel plugin to do Psych calcs. Someone after me translated it into a python script which if works you might be able to integrate into labview, or you can use the excel plugin to generate look up table perhaps.

The chapter of the ASHREA book is posted as a PDF in the zip file.
If you just need to do one implementation you may be able just to use the equations from the book.
