SS-250/SS-240A
■Supports various applications
Displays its capabilities in full force in current waveform observation and wide-bａnd applications such as switching power supplies, optical disc manufacturing lines, and semiconductor power devices.
■Features
Low noise characteristics for easy milliampere order observation
Wide bandwidth - DC to 100 MHz (SS-250)/DC to 50 MHz (SS-240A)
High sensitivity and wide bandwidth implemented through use of thin-film Hall element
Power can be provided directly from the oscilloscope
(DS-5600A/DS-5400A series of oscilloscopes with DS-579 : Probe power option)
Clamp type, enabling easy measurement without cutting the electrical circuit
Equipped with a function that provides simple protection for excessive input
Can also be used with measuring instruments that do not have a power supply for probes (power can be provided through the optional probe power supply PS-26)

* These current probes can be used as-is with oscilloscopes that feature power supply connectors for active probes. Current probes can also be used with oscilloscopes without power supply connectors for active probe, when used in combination with the optional power supply (PS-26).
* With the power supply for current probe PS-26, if the current being measured is large, it may not be possible to use two SS-250/SS-240A units at the same time.
■Caution
1.Use this product in circuits that do not exceed the maximum usable circuit voltage, so as to avoid accidents such as short-circuits and physical injuries.
2.Do not use this product with bare conductors, so as to avoid accidents such as physical injuries and short-circuits when the leading end of the clamp core is opened.
