Omicron CPC 100 Reference Manual

Resistance
7 - 3
Resistance - µΩ Measurement
Use the Resistance test card to measure test objects with very low resistance,
such as a contacts, windings etc.
To do so, CPC 100 injects DC current into the test object, measures the current
that flows through the test object, and calculates the test object’s resistance.
The Resistance test card provides a total of three output ranges:
•400ADC
•6ADC
• V DC (2 wire)
The test setup depends on the selected range:

measurement in the
400A DC range
Inject current from 400A DCoutput to both sides of the test object. Input VDC
measures the voltage drop at the test object, the current is measured internally
by CPC 100, and from these values the software calculates the test object’s
resistance.
