VDAS® MKII explained The VDAS ® MkII hardware is a computer interface module and connects the sensors and instruments of a TecQuipment VDAS ® -compatible product to a suitable PC running the VDAS ® software. Manually recording data from experiments can be difficult – it takes time and can be repetitive. Some experiments require the user to take many readings from several instruments in a short time. Other experiments require the user to take regular readings over several hours or days. It is often necessary to adjust controls and instruments while taking readings. Humans can also make mistakes when they read an instrument, write down the data, or enter it into a computer. This can lead to errors in the data and may give faulty results. VDAS ® MkII is an excellent tool for use with many of TecQuipment’s products. It removes the need to read, record and save data from experiments manually. It also reduces the chance of human error. VDAS ® can record lots of data in a short time, or automatically take readings over several hours. It also saves the data in electronic form so the user may view it later, or produce charts and tables. VDAS ® software works with VDAS ® MkII-compatible hardware to display real-time traces and record analogue data as a user-friendly alternative to an oscilloscope on selected TecQuipment products. DATASHEET
As a real-time data capture device for engineering experiments, VDAS ® MkII works with a growing list of over 90 TecQuipment products (see page 7). There are three types of VDAS ® interface:
Bench-mounted VDAS ® unit (VDAS ® -B) A hardware unit that sits on a bench and can serve many benchtop pieces of VDAS ® -compliant equipment in a laboratory. Frame-mounted VDAS ® unit (VDAS ® -F) A hardware unit that is mounted on a frame and can serve many pieces of VDAS ® -compliant equipment in a laboratory. The above units are electronically identical, but their cases are physically different. VDAS ® Onboard

The VDAS ® MkII interface is built in to the TecQuipment product and therefore requires no additional hardware.
