Measurement and Instrumentation In DC potentiometer measurments, a second reading is often taken after reversing the polarities of the DC supply and the unknown voltage and the average of the two reading is taken. This is with a view of eliminate the effects of Stray thermal emfs. Stray magnetic fields. Errorneous standardisation. Ripples of the DC supply. Stray thermal emfs. Stray magnetic fields. Errorneous standardisation. Ripples of the DC supply. ANSWER DOWNLOAD EXAMIANS APP
