Select the liquid and set the bath temperature.
Take at least twelve readings spanning the recommended window for that liquid.
Plot ln P against 1/T, fit a straight line and obtain L from the gradient.
Compute the boiling point at 101.325 kPa from your fit and compare with the accepted value.
Repeat for at least three liquids, and for the unlabelled one.
