Measuring Input Offset Voltage
... Input Offset Voltage = (Vref to Vout) / ((R7/R8) + 1) = (Vref to Vout) / 101 Alternatively, with this circuit configuration, the Input Offset Voltage can be measured between the input terminals of the op amp. R9 & R10 eliminate any offset at the output due to Input Bias Currents therefore any offset ...
