*	It can be used as it is for the model that has the power supply terminal for the active probe in the oscilloscope body. In addition, for models that do not have a power supply terminal for active probe, you can use this current probe by using a separately sold power supply (PS-26).
*	If the input BNC terminal of the oscilloscope is buried in the outer case and the SS-250/SS-240A connection is obstructed (Our product is Simplified King), please prepare a conversion BNC plug for the jack plug. ..
*	When the SS-250/SS-240A is used with an oscilloscope equipped with a probe power supply and the measured current value is large, the current probe power supply PS-26 may be required.
*	If the measured current value is large, the PS-26 power supply for current probe may not be able to use two SS-250/SS-240A simultaneously.

Note
1.	To avoid short circuit and personal injury, please use this product on the electric circuit below the maximum operating circuit voltage.
2.	Do not use with bare conductors to avoid a short circuit or personal injury when the tip of the clamp core is opened.
