Test Port
The 880 is designed with two test ports: the 3-terminal port for convenience and a 5-terminal
port for higher accuracy.
Figure 3 - Test Ports
The standard banana plugs allow the connection of banana to alligator test lead. This
configuration has lower testing accuracy when compared to the 5-terminal test port. The test
lead length should be kept as short as possible.
For a more accurate measurement when using external testing leads, the 880 LCR meter is
designed with a 5-terminal test port and exclusive test fixtures that provide a 4-wire connection
with a shield for increased measuring accuracy.
