Its bold new look is matched by its menu-driven Windows CE™ based interface. This powerful tool is also easy to use and intuitive enough to master in minutes. While the handheld style makes it great for field service, this meter can also be networked via USB or RS-232. A special USB cable is included, while a special RS-232 cable may be purchased separately. The built-in features of the 842-PE include a complete statistics package that lets you choose between a line plot and a histogram. Using the same screen enables you to set the data sampling parameters depending on whether a power or energy detector is being used. It is easy to recover data from measurement interferences: for example, the last value or the last period in the statistics buffer can be canceled, enabling you to continue without stopping your work. In addition, you can zero your reading when measuring pulse energy. There are also many options for saving data, saving statistics, or both. The 842-PE meter is equipped with a DB15 input connector for direct compatibility with Newport's 818P Series High Power (Thermopile), 818E Series Energy (Pyroelectric) or new 918D and 918L Series Low Power (Photodiode) Detectors. For interfacing with 818 Series Low Power Detectors, the 841-DIN adapter can be used (ordered separately).
