Internally i don't believe the voltage input jacks on the meters are fused... just the current inputs.

Don't know about the others but the Fluke 88 has fuses for both current and voltage.

The Fluke 88 only has fuses for current. One fuse is for the low current and one is for the high. Voltage does not need a fuse becasue it is a high impedance input.

Re: AC / DC Amp Meter Question

yeah its like a 50 megaohm input.... to high to draw any current at pretty much any voltage.
