Micro-Ohmmeter Model 6250

CHAPTER 8
APPLICATION EXAMPLES
The proper procedures for using the Model 6250 in some specic applica-
tions are outlined throughout this section.
8.1 Measuring Winding Resistance of Motors
and Transformers
WARNING: Prior to and after testing a transformer winding, the energy
stored in the magnetic field must be dissipated by shorting the trans-
former terminals. For additional safety, the transformer terminals should
be jumpered together before the instrument is disconnected.
One terminal of the sample should be grounded for safety!
Make connections to the transformer as shown in Figure 8-1. On larger
transformers, the measurement stabilization time will increase.
