The Model 841-P-USB Virtual Power Meter is easy to use and intuitive enough to master in minutes. A USB cable is included with the meter to connect to your PC or laptop computer, though which the device is powered up. Its low cost and small form factor makes it an ideal tool in a manufacturing setting, busy labs with small workspaces, or in a suitcase of a service engineer.
The built-in features of the 841-P-USB Software include a complete statistics package, which lets you choose between a line plot and a histogram. Using the same screen, the user can set the data sampling parameters. It is easy to recover from measurement interferences. For example, the last value or the last period in the statistics buffer can be cancelled, enabling you to continue without stopping your work. There are also many options for saving data, saving statistics, or both.
