I just had to try out the sweep functionality of the 2450 on a 12V zener. Very easy to set up and the graph mode is very functional.The pan and zoom is a little slow and seems to have a glitch if you zoom in too far. Still very awesome.
As graphed with auto on X and Y axis Y is in linear mode
As graphed with auto on X and Y axis Y is in Logarithmic mode. Notice Amperage is shown as all positive ??????
Zoomed on the knee of the Linear Y graph
Zoomed on the knee of the Logarithmic Y graph
Zoomed on the forward conduction of the Logarithmic Y graph
Time to get back to getting used to this unit and doing the review.
