I just did that,and the meter flicks between .1 and .2 ohm's-->so no where near 1 ohm.
Dont forget this error(if there is one)must also be accounted for on R1-not just R2. So if R2 is a higher value than that indicated,and the P/out is less than indicated,then R1 is also a higher value by the same amount,and thus the P/in also decreases.

Tinman,

But the converse is true if the measured 10R3 values are too high, as I suspect they are.  The measured 98R4 resistor value could be off a bit as well (re the meter's .8% accuracy spec).

My leads here are typically in the 0R1 to 0R3 range, depending on how clean the connections are.  For greater precision I use the four wire resistance mode.  You can do the same if you have an accurate current source.  I agree, 1R for test leads sounds really high. 

Why the "if there is one" comment?  You do understand the discrepancy being discussed don't you?

If it is not the CVR value that is off, then what is? Obviously we can't have two different currents in a series circuit.

Or it is somewhat inductive. Measurements are at DC. What does it measure at 3kHz?

.99,

At around 0.2milliohm reactance per 10nHy @ 3KHz, I doubt that much error is related to inductance.  "Most" carbon film resistors are relatively low inductance in the 10's of nHy range.  However, some do have fairly large inductance depending on construction.  But at 3Khz?

Just throwing possibilities out there.

Maybe it's not carbon.

If the meter leads really are only 0.2 Ohm, that can't account for the discrepancy, so one other possibility is that the meter is not very accurate in the 10 Ohm range.

What Brad needs is a 1% or even 0.1% 10 Ohm and 100 Ohm non-inductive resistor for this test. Then he will know how good his meters are at 10 Ohms measurements, and the test results might make more sense.

Ok,i just went and checked the resistors a different way.
I supplied 1 volt across the 10 ohm resistors with my power supply,and used my scope to make sure there was 1 volt across the resistor. I used my DMM set to the 10 amp scale to measure the current. The DMM has a .1 ohm shunt resistor to measure current on the 10 amp scale.
The current measured was 96mA. This gives us a resistance of 10.416-minus the .1 ohm shunt in the DMM. So the measured resistance of 10.3 ohms has now been measured in two ways.
