LEADING-EDGE VIBRATION ANALYSIS
What’s the best way to transform a good product into something that is truly best in class? Listen to your customers, of course!
Using as our benchmark the legendary vb3000™ instrument, our most popular portable vibration analysis instrument, we engineered the all-new vb7 instrument’s electronics from the ground up using state-of-the-art, lightweight components; we then sculpted the vb7 instrument into a superbly comfortable tool designed both by and for predictive maintenance professionals.
Delivering unmatched customer value is the core philosophy driving Commtest’s innovation efforts. We understand that what you value most is the ability to complete your work as quickly and comfortably as possible, confident that you are getting high quality data first time, every time. With customer feedback directly guiding our product development, the all-new vb7 instrument offers usability enhancements that are sure to make your working relationship a pleasant one.
The vb7 instrument’s elegant ergonomics are what catches the eye first. The vb7 instrument has been contoured to fit comfortably in your hands, providing hours of strain-free use. Also employed is an innovative neck-strap attachment system designed to ensure that the instrument remains horizontally balanced while collecting data. The keypad offers true right and left-handed operation using raised keys that provide a reassuring tactile response. On-screen menu choices are highlighted with intuitive icons, ensuring a minimum of key presses are required to access the most frequently used functions.
In addition to refined ergonomics, a larger and clearer LCD display now provides simultaneous two-channel display with enhanced graphic capabilities.
Just one of the vb7 instrument’s enhancements that must be experienced first-hand is its amazingly light weight: fully 40% lighter than its predecessors. The vb7 instrument offers true two-channel on-route data collection with data collection speed further maximized by Commtest’s unique patent-pending adaptive settling technology. In addition, the vb7 instrument offers a battery life of over ten hours, fast data transfer via USB and Ethernet, and a massive 1 GB of onboard memory. Together, these refinements mean you will spend less time with your vb7 instrument sitting idle connected to the battery charger or PC, and more time out in the field.

The vb7 instrument is an all-in-one tool suitable for every level of vibration analyst, from novice through to expert. The Ascent ® software contains the collective experience of over 25 years of expert in-depth machine fault analysis.
1. Users with no prior experience or without previously recorded vibration history can now establish a measurement program utilizing proven baseline values from ISO standards and “The Proven Method” from Technical Associates.*
2. Experienced users can now generate meaningful spectral alarm bands automatically rather than just relying on basic overall alarms or spectral band guesswork. Statistical alarm creation ensures that families of similar machines are compared consistently against developing trends.
3. Veteran analysts can now objectively evaluate and compare their findings against a time-tested and proven historical foundation. Statistical alarm editing and adjusting ensures the alarms remain fine-tuned for maximum usefulness.
