Chart recorder features digital storage

The ViewGraf is a novel combination of digital storage and chart recorder providing a comprehensive presentation of signal data.

The ViewGraf is a novel combination of digital storage and chart recorder providing a comprehensive presentation of signal data.

Data acquisition to an onboard hard disk enables recordings to be made over long unattended periods, or archived for further analysis.

Alternatively an 11in writer can be installed to provide high quality paper output giving an instant hard copy record.

The 12.5in removable display presents a real-time display and fast post-storage analysis of the data.

ViewGraf offers high-performance signal condition on up to 32 channels, and up to six input positions provide for differential, strain/bridge, accelerometer and thermocouple capability coupled with 12 or 16bit acquisition resolution.

Additional computed waveforms are available using math on individual channels or channel combinations to provide live analysis.

Digital storage rate is up to 500Ksample/s with 100% pre or post trigger and with paper speeds to 100mm/s.

The control provides ease of access to the chart speed, amplifier spans, signal position, display speed and start/stop of the acquisition and chart for fast response during testing.

Connectivity and data transfer is available via USB, Ethernet or removable Zip drives.

ViewGraf's modular design enables systems to be configured to meet specific requirements.

This configuration flexibility makes ViewGraf suitable for a wide range of applications.

The front panel and display is detachable for remote control and display viewing and the signal conditioners are modular to configure the input channels for any type of signal.

Even the real-time writer is removable, allowing you o use the system as a traditional chart recorder; or, remove the writer to take the system into field applications, acquire the data, and output on the chart paper for review in the laboratory environment.
