Although data measurement and recording techniques have improved dramatically over the years, producing greater amounts of useful data, analysis techniques and operator interface technologies haven’t fully kept pace. Operators can view and study this data without having to use a separate PC and special software. The latest generation instruments benefit from secure high capacity data storage, able to save months or even years of historical data within the device. Modern data acquisition instruments are replacing old recording technologies such as pen and ink chart recorders. More advanced systems can securely save data for viewing on demand, this is particularly useful for reviewing historical data, and comparing this data to present conditions. These instruments use color graphical displays to allow operators to view input signal data, and to control equipment or processes in real time. The most common method for viewing and analyzing information is through data acquisition and oscilloscopes. Testing facilities and research laboratories often find themselves drowning in data, and struggling to use data in meaningful ways to improve operations. Therefore, little or no training is required to introduce multi-touch to the end user, resulting in quick adoption and immediate gains in productivity and effectiveness.įigure 1: Multi-touch technologies implementation in tablet PC and data acquisition enables remote control and data analysis through Bluetooth or WiFi. In addition, multi-touch technology has become intuitive to most all engineers due to the proliferation and widespread use of smartphones, tablet computers and other handheld electronic devices (Figure 1). This three-fold increase in productivity is made possible because two-point touch technology condenses multiple touch-and-click operations into a single fast swipe action. One of the main reasons for this trend is that multi-touch screen manipulation is three times faster than with knobs and buttons, greatly increasing operator efficiency and productivity. Multi-touch technology is rapidly migrating from smartphones and tablet computers to test & measurement instruments. One of the main responsibilities of engineers and technicians is data analysis, and this article will show how multi-touch technologies can be used to improve the performance of this and other related tasks.
