You must click S1, S2, or S4 to initialize program.
Selecting a new Fault requires that you initialize program by selecting No
Fault and then closing one of the switches.
Failure to initialize program results initial fault to remain in circuit when a new fault is selected.
Vout will always equal an integer between 0 - 7 and will not deviate from an integer voltage by more than .02 volts. See animated schematic top of page.
Operational Amplifier Gain (Minimum) = 100000
Operational Amplifier Input Offset = 1mV (Max.)
Resistor Type = precision ( + or - 1% )
Maximum closed switch resistance = .5 ohms
= 15.0 + or - .05 Vdc
Vneg = -15.0 + or -.05 Vdc
R2 is 8200
S4 closed resistance high
Vneg = -14.88
R4 = 1031
