INTELLIGENT RECORDER HELPS PROCESS FIRM TEST TRANSMISION FLUIDS.

Recent developments in data recording have resulted in 'intelligent' chart recorders that can record twelve or more channels of information in graphical form and simultaneously print the data in numerical columns with 0. 01% accuracy. These can also record test or process setup conditions, analyze the data, calculate, and print summaries of the results. In the application discussed here, a Dianachart Model DC-12 recorder replaced a lightbeam oscillograph in a system that provides precise data on the performance of various types of transmission fluid. The DC-12 recorder can accept 12 input channels, digitize them, store them in internal buffer memory, and print them out in graphical or tabular form using a dot-matrix printer, with full annotation.
