The true RMS AC/DC clamp-on ammeter 393 FC with safety in accordance with measurement category CAT III 1,500 V was developed for PV installation and maintenance engineers who work in applications with high DC voltages. Connect the measuring lines securely to the clamp-on ammeter to measure the voltage and current of individual panels or a series of panels in PV-systems. The PVLEAD1 test leads with MC4 connectors are used for regular testing and measurements and for troubleshooting PV solar modules. When using the PVLEAD3 SOLAR MC4 test leads, the power cables can remain connected during the measurements. This allows measurements to be made during operation. Use the IRR1-SOL irradiation meter to determine the solar radiation required to calculate the current voltage characteristic of the output power. Check if the panel or the series of panels is delivering the correct voltage.
