Meaning of "Scaled" and "Inverted" in context of picoammeter analog voltage output I'm trying connect a picoammeter to an oscilloscope, and I noticed that its analog voltage output was described as "scaled" and "inverted". I'm just curious as to what that means about the oscilloscope is going to "see". Very new to electronics, and cursory google searched yielded many pages using the adjectives "scaled" and "inverted" but all with the assumption that I knew what they meant. What do they mean? What is the signal scaled to, and what does the fact that it's inverted imply about how its processing the current measurements...? If that question even makes sense. Thanks much.
