The MW 3517BF is designed to include all the functions necessary for the maintenance and installation of photovoltaic (PV) panels. It can measure AC voltages up to 1500V and DC voltages up to 2000V using the optional SA163 probe adapter specially designed for measurements on  photovoltaic installations.

All the normal functions of a multimeter are present including frequency, capacitance, resistance, continuity and diode test modes.  It is also possible to measure currents up to 600A AC and DC or up to 3000A AC using the optional SP295 or SP296 Flex clamps.
An integrated datalogger function allows you to record all types of measurements with selectable intervals of 1, 15, 30 or 60 seconds.

With its Bluetooth interface you can monitor your measurements and record them in real time on your phone or tablet using the dedicated app (Android or iOS).  The recorded data can be downloaded and exported via the tablet or the smartphone in .csv format for display or processing in a spreadsheet or other software.
