Linear Recording Instruments
The Versagraph's Reverse Chart Drive puts you a step ahead. Because t h e 8 0 0 Series Versagraph™ precisely feeds chart paper in either direction, sequential analytical runs can be made exactly side by side, or even superimposed, on a single sheet for convenient and accurate comparisons of an entire series. Especially useful as a quality control instrument, the Versagraph permits variations from Acceptable Quality Level Standards to be iden tified at a glance. And priced at only $1095.00. it's much less than you'd have to pay for much less. Compare a few of the exclusive Versagraph features: Front Loading Paper Another breakthrough in flatbed design. Lift the front deck, drop in the paper, engage the chart drive, and you're ready to run. All from the front. The Versagraph feeds paper
like a fine movie camera feeds film, forward or reverse and always under your precise control. Signal Fine Tuning To give you better control of specific signal levels, we added a fine tuning control system that can "zero in" on the specific portion of the signal that's important to you. A calibrated 1 % incremental increase or decrease of the recording scale up to 9 9 9 % is made possible by digital control circuitry; and push button calibration of full scale on any range offers exceptional recording versatility. Unique Pen Drive Control The inability of recording pens to respond to small signal changes is a problem usually defined as Deadband ". The Versagraph doesn't have it. D u e t o a p a t e n t e d ' Pulse
Modulated Servo Drive System that consumes very little power, heat and zero drift are minimized, and deadband is, for all practical purposes, eliminated while linearity and accuracy are enhanced. We could go on about the built-in event marker, Automatic servo shut down protection, right or left zero, and our 1 cm/sec top speed; and we do in the Series 800 Versagraph Bulletin.
