=====Resistive Bridge Testing=====

==Five Lump Element Resistive Bridge==
In-1-2-3-4-Out
^          ^ 1st ^ 2nd ^ 3rd  ^ 4th  ^ 5th  ^
| R (Ohms) | 6.3 | 12  | 17.6 | 23.5 | 29.2 |
| V (mV)   | 35  | 52  | 71   | 87   | 98   |
This is working as expected.

==Aluminum Strip (Wire Bonded)==
In-1-2-Out
^          ^ 1st ^ 2nd ^ 3rd ^
| R (Ohms) | 4   | 5   | 6.2 |
| V (mV)   | 41  | 61  | 93  |
This is working as expected.

==1st Chromium Strip (Not Wire Bounded)==
In-1--2----3--------Out
^           ^ 1st ^ 2nd ^ 3rd ^ 4th  ^
| R (KOhms) | 2.0 | 2.9 | 4.1 | 7.7  |
| V (V)     | 1.2 | 2.5 | 5.2 | 10.4 |
This is working as expected.
\\

==2st Chromium Strip (Not Wire Bounded with Surface defects on the second half)==
In-1--2----3--------Out
^           ^ 1st ^ 2nd ^ 3rd ^ 4th  ^
| R (KOhms) | 2.5 | 5.0 | OL  | OL  |
This does not work. This method is sensitive to any surface and volume defects.

==Wire Bonded Chromium Strip==
In-1-2-3-4-5-6-7-8-Out
^           ^ 1st ^ 2nd ^ 3rd ^ 4th ^ 5th ^ 6th ^ 7th ^ 8th ^ 9th  ^
| V (V)     | 1.5 | 2.5 | 3.5 | 4.3 | 5.1 | 6.1 | 7.2 | 8.2 | 10.1 |
This works just the way we expect.

There was a 10th wire bound but it failed to bond the first time. This lead to a poor contact resistance. As a result it's resistance was equal to the rest of the system combined. This shows the potential problem with wire bonding!
