Micro-Ohmmeter Model 5600
Application Examples
The Model 5600 performs reliably on a variety of low resistance
situations. Typical applications include:
• Contact resistance of breakers and switches
• Wire to terminal connections
• Winding resistance
• Motors and generators
• Aircraft and rail bonds
• Grounding connections
• Many other very low resistance samples
The proper procedures for using the Model 5600 in some specific
applications are outlined below.
Measuring W
inding Resistance of Motors and Transformers
CAUTION: Prior to and after testing a transformer winding, the
energy stored in the magnetic field must be dissipated by shorting the
transformer 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 7. On larger
transformers, the measurement stabilization time will increase.
