A system and method for process instrumentation and control equipment. The system including a paperless, microprocessor-based, panelboard recorder having built-in data acquisition functions, a mechanism for archiving data, and a variety of display types. Memory space is conserved by deriving quantized data comprising signal samples received at a first rate and storing them for a first relatively short period in a fine quantized memory, and storing in a coarse memory, for a longer period of time, a subset of said signal samples recurring at a rate lower than the first set and having fewer quantized levels than the first set of samples. The operator can then determine whether coarse data obtained over a relatively long period or fine data obtained over a shorter period are displayed.
