NOTE: Additional test voltage and current restrictions of the 3550 unrelated to test fixtures apply for
measurements exceeding 1MHz.
Frequency Measurement Range
42Hz ~ 10kHz 100mƻ ~ 1Mƻ
10.1kHz ~100kHz 1ƻ ~ 100kƻ
101kHz ~ 1.00MHz 10ƻ ~ 10kƻ
The Model 3510 Radial/Axial Lead adapter is a
general-purpose accessory used for testing
components with radial or axial leads. Components
are tested by plugging the leads directly into the
adapter sockets.
The Model 3510 is designed for 5-terminal
measurements and is capable of measuring a wide
range of impedances.
Model 47454 Kelvin Klip Leads are designed for 5-
wire, Kelvin measurement of all types of component
styles. They may be used for both low and high
impedance measurements.
Kelvin Klips are particularly convenient for low
impedance test devices or components with short
leads, however, the measurement frequency and
impedance range are limited as shown in Table 4.4.
Exceeding the recommended measurement ranges
may result in erroneous and inaccurate readings.
