Abstract
A method for testing body components of pulsed droplet deposition apparatus comprises applying a variable frequency voltage to the electrodes of each of a number of selected channel wall elements. The resulting impedance variations are used to determine the natural frequencies of the selected wall elements which, in turn, are used to determine whether the compliance ratios of the selected wall elements and the droplet liquid to be used therewith lies within a desired range of values.
