The 844-PE-USB Virtual Power Meter with a USB connection uses a computer as the instruments monitor, allowing the user to access the full computational power of the computer. When equipment space is tight or you need to control multiple power meter channels, 844-PE-USB is an ideal solution. In addition to USB output, it also has a configurable analog aoutput that reach from 0-10 V for full scale represntation. Installation of the application is simple and includes the USB driver installation. PMManager™ is a powerful application software that controls the power meter and takes measurement data.
