This differential probe extends the measurement capability of
oscilloscopes in electronic power converters, inverters, motor speed controls, switch mode power supplies and many other
applications by enabling conventional oscilloscopes to display and measure in-circuit waveforms that are referenced to high common
mode voltages. The 4241A meets EN61010 Category II
Requirements and is ideally suited for measuring high-speed voltage
surge in power electronics circuits.

*Voltage limit is the lesser of the DC+Peak AC and RMS values.
** a. The supplied voltage must be less than 12V and greater than 4.4V,
otherwise the probe could be damaged or will not work properly.
b. Polarity is "+" inside and "-" outside. For wrong polarity, built-in
circuit protects the probe, no danger or damage will occur.
c. When the voltage of the cells become too low, the power indicator on the
panel will flicker.
