PDB182 dual-gang tracking and load swap
Campaign 154 author draft for batch 016. The complete reader accompanies this experiment archive.

Use the exact PDB182-K420K-103B1 with the verified six-terminal map.
Apply a 3.00 V supply limited to 5 mA. Keep both wipers electrically separate.
Keep the shaft at each mark as you change the single load with power off.
Measure both track totals and the disconnected load in ohms.

Fill in the blank worksheet or try the constructed example:
    python3 tracking.py constructed-examples.csv --track-a 10000 --track-b 10000 --load 10000
    python3 -m unittest -v test_tracking

Replace the example resistance arguments with measured values for bench data.
The example contains constructed values. No physical tests have been performed.
