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 ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
