*Connect the null detector II common lead to the low terminal of the TI, and wait until the thermal emf
caused by the heat from the operator's hands has subsided.
4.3.7 Set the null detectors operate–zero switch–to zero.
4.3.8 Set the voltage sources for minimum output, and disconnect the test configuration.
