You get what you pay for and then some. The Superscribe™ Series 4900's pen positioning system utilizes a unique capacitance transducer rebalance element. Developed by Houston Instrument, the capacitance transducer
eliminates many of those problems associated with the conventional resistence slidewire type rebalance recorder. Since this patented innovation is a non—contacting device the slidewire wear resulting in "glitches" and "noises" inherent in conventional recorders is thereby eliminated. The results—increased recorder life, accuracy, reliability and infinite resolution.

Features 280 switch selectable chart speeds. A 3-position RUN; STOP; ADVANCE switch is also provided for local control of the chart. Remote control of the chart is accessible through a rear input connector. A toggle switch allows for local up/down control of the pen. Also accessable through a rear connector for remote control. Fourteen calibrated ranges in a 1—2—5 switching sequence from 1MV full-scale to 20V full-scale. Variable control gives between range span adjustments. Push-Button and front panel Zero control provides positioning of the pen from - 1 0 % to + 1 1 0 % of full-scale. Pen response 0.25 sec. from zero to full scale. Optional integrator is a modern, inexpensive all solid-state integrator which is independent of line frequency and responds instantly to the input signal. The integrating trace is displayed along the zero base and gives 100 counts per transverse with a " b l i p " every 1000 counts. A front panel "integrator balance" is provided to compensate for base line drift. Circle # 8 5 for literature Circle # 8 6 for a representative to call
