This report is the first of a series that describes the quantitative data analysis and the results obtained with ARNICA at the TIRGO during the commissioning of the camera (November 1992 -- June 1993).  The series of reports is based on broad-band data acquired in nineteen nights at the telescope (11 nights in December/January, 4 nights in February, and 4 nights in March), as well as data from laboratory tests.  Presented here in the first report are the techniques used to characterize the detector and the derived parameters.  In particular, we analyze detector performance in terms of:  1) conversion factor or gain; 2) read noise; 3)~dark current; 4)~non-linearity and its correction; and 5) cosmetic quality and the correction for bad pixels.
