[Elecraft] [OT] dumb question about oscilloscope probes

I like the way scope probes have a tip that hooks onto a component lead, 
and a little alligator clip for the ground. So I thought I could use a 
passive scope probe in the X1 position on my DVM too. I hooked one up 
with a BNC-bannana adapter, but it turns out that there seems to be a 
series resistance of about 250 ohms, which is inconvenient for 
resistance measurements. I got the same result from several probes.

My question is, what's going on here? Schematics of probes I found all 
showed that in the X1 position they were straight through.
