... The other model has four test voltages of 50, 100, 250 and 500 Vdc measuring insulation resistance up to 1000 MΩ. The only other difference between the five analog models is the type of power source. Power for models MJ159 and MJ160 is derived from a low-voltage, hand cranked generator which has bee ...

1 Measuring resistive devices
... Real voltage sources, however, always have internal resistances, resulting in parasitic voltage losses within the source itself, and they have power limits which restrict the amount of current that can be sourced. In general, we can model a real voltage source as an ideal voltage source ∆V in series ...
