The 670C Display Unit has a front panel that allows for full control of all the instrument’s features. All functions can be monitored and controlled via the RS-232 interface. Range switching may be done manually or automatically with the 670C, selecting the lowest possible on-scale range. A key-lock switch on the front panel determines Local or Remote control. The 670C may be used with any sensor Full Scale and will display pressure in any one of 12 engineering units. Sensor response time may be set for 1, 40, or 400 msec, and a data averaging feature allows the user to average signals from 0.1 to 10 seconds, to optimize the pressure readings for transients or noisy pressures.
