* When using the Z3003 Multiplexer Unit, ensure that the total of the unit’s internal wiring
resistance (including relays) and the wiring resistance from the connector to the measure-
ment target does not exceed the values in the above table.
You can verify that the unit’s internal wiring resistance is 1 or less using the self-test.
See: "8.6 Performing the Multiplexer Unit Self-test" (p.166)
