Generating Multiple Calibrating Voltages SimultaneouslyCalibrating unit containing signal generator controlled by microprocessor puts out ac signals of known voltages on fifty channels simultaneously. Signals used to calibrate high-frequency tape recorder channels for multiple, ac-coupled strain gauges simultaneously. Calibrating voltage required on each tape channel determined by remote computer, and corresponding data and commands transmitted to microprocessor via modems.
