Solar Application specialist, Will White, walks through the screens and user interface of the Fluke SMFT-1000 Solar Multifunction PV Tester www.fluke.com/en-us/product/e...
With this device was impossible to check I-V curve for N type PV panels. I have try with two model (astroenergy CHSM54N-HC 425Wp and trina other model ) and the device returns error no. 14 - Isc current overloaded. I have send the panels to a laboratory and and they are good. It is not written anywhere that N type panels cannot be tested.
