Resistor Matcher

Would this work?

My lame meter only has 20k/V of resistance, so at .1V range, it's only got ~2K of resistance, so I cannot match resistors of large resistance with just a wheatstone bridge.

The only connections not shown in the diagram is the Null offset, which is not available in CL. I still need to figure out the exact values for R 14, 15, 16, but basically they would set my input impedance and thus the sensitivity of the circuit (for different test resistor ranges).

first of all you can check resistance R9.
