 +==== AD5940 Z Test Board ====
 +
 +The AD5940 Z Test board is designed to model skin impedance, body impedance, electrode contact impedance and electrode impedance. There are 5 banks of switches on the board labelled S1, S2, S3, S4 and S5. The function of each bank is described in the following table: 
 +^ Switch Bank ^ Bank Function ^
 +| S1         | Used to model Body Impedance  |                
 +| S2 | Used to model contact impedance on F+ electrode |
 +| S3         | Used to model contact impedance on S+ electrode |
 +| S4         | Used to model contact impedance on F- electrode |
 +| S5         | Used to model contact impedance on S- electrode |
 +
 +The following tables indicate the resistor or capacitor value associated with each switch in the bank. Moving the switch to the ON position connects the corresponding resistor or capacitor value in series on the signal path. If more than one switch is active the corresponding resistor values are connected in series.
