Installation 3–2
The instrument is not suitable for battery operation.
The power switch is located on the left of the front panel.
3.3 Location
The 4300 is intended for use either on the bench or in a rack. The instrument is convection
cooled and care must be taken not to restrict any of the air inlet slots.
3.4 Measurement Connections
The 4300 can be used with any of the following Wayne Kerr leads, fixtures or adaptors. In each
case ensure that the colour-coded BNC connectors are mated correctly with the corresponding
front panel BNC’s.
Kelvin Clip Leads Part No. 1EVA40150
General purpose 4-terminal measuring leads for conventional components giving good accuracy
except for measurement of very small capacitances or very small inductances where the use of
the 4-terminal component fixture, part number 1EV1006, will give better results.
Kelvin Clip Leads ((large jaws), Part No. 1EVA40180
Similar to part number 1EVA40150 but with larger jaws making them more suitable for
connection to terminal posts or larger diameter component leads.
Four-Terminal Lead Set, Part No. 1EV1505
600mm screened cable terminated in four crocodile clips at the component end. Not
recommended for use above 30kHz.
Four-Terminal Component Fixture, Part No. 1EV1006
Remote fixture with sliding jaws to accommodate both axial and radial leaded components.
This fixture will give the greatest accuracy for 4-terminal measurements of conventional
components. The jaws can be set to the component width for trimming and component
measurements can be performed without moving the measuring leads: stable lead positioning is
important when measuring low value inductors.
