What is the difference between the ML11 and the ML12 Test Load Boxes?
The ML11 consists of a fixed capacitive load, while the ML12 consists of a fixed resistive load. Basically either type can be used on any ROD-L unit, but note that the M100DC units, because they supply a purely DC waveform, will not show any current with the ML11 boxes. The “fail” posts on the ML11 and ML12 boxes are floating points.
