About this app

This app allows you to control a Larson Davis HVM200 through WiFi. The HVM200 is a hand-held or worn instrument for measuring human exposure to potentially harmful vibration, performing relevant calculations and providing overall metrics. As a measurement is performed, each axis and the vector sum can be viewed and displayed in real-time. View and modify instrument settings from your phone or tablet to customize each measurement.

If you have multiple HVM200s, the app can find and display a list of meters. From this list you may select an individual HVM200 to view or configure. You will need to configure your HVM200s to use the same WiFi hotspot as your phone or tablet. Alternatively, you can also set your HVM200 to access point mode and connect your phone directly to the HVM200.

Human Vibration Exposure

Exposure to high levels of vibration has been shown to cause permanent injury if left unchecked and untreated. Determining potential for injury from exposure to vibration should be considered part of a comprehensive ergonomic evaluation and risk assessment program.

The HVM200 from Larson Davis, a PCB Piezotronics division, provides a portable, practical means for quantifying exposure on the job, whether the work is performed inside manufacturing or process plants or at the most remote agricultural, mining or construction sites. Features in the HVM200 support the measurement of Hand-Arm Vibration (HAV), Whole Body Vibration (WBV), and general low-frequency vibration. Detailed vibration levels are easily stored on a removable SD card. These vibration measurement files can then be downloaded to a PC for analysis and archiving.

Product Compliance Testing

Measuring all three axes of vibration simultaneously greatly simplifies the setup of a test and enhances the repeatability and correlation of the vibration data. From the three channels of measured data, the HVM200 automatically calculates the important vector sum information and presents it as a fourth set of data values. For compliance with the latest measurement standards, the HVM200 employs digital filters for each channel that can be enabled as needed.
