FIXTURE
A versatile test fixture is provided with the
SR715/720 that provides a 4 wire Kelvin
connection to most types of leaded devices. (A
Kelvin connection uses two wires to carry the test
current to and from the device and two
independent wires to sense the voltage across the
device.) This prevents the voltage drop in the
current carrying wires from affecting the voltage
measurement.
Radial leaded components (where the leads are on
the same side) are simply inserted into the test
fixture, one lead in each side.
Axial leaded devices (leads at opposite ends)
require the use of the axial fixture adapters.
Surface mount (SMD) devices or components with
large or unusually shaped leads can be measures
with SMD tweezers or Kelvin Clips. A BNC adapter
is available for interfacing to remote fixtures.
If the device leads are dirty or coated with wax,
clean them before inserting them in the fixture.
See the maintenance section for information about
cleaning the fixture.
