“A 9-inch color CRT is contained. Both test results and waveforms are displayed on the CRT screen. If measurement is made three times to obtain the best result, the respective respiratory waveforms can be displayed simultaneously in different colors for the convenience of selection. Records are printed by a silent thermal printer. This model can be conbnected with FNV-600N (OPTION), to allow the closing volume, N2 wash out and FRC to be measured on the nitrogen open circuit method. Furthermore, this analyzer can be modified to be connected with a general purpose computer, for transfer of test data. A special table is available on request.”
