Differential Probe for Power Management- Model 4237
Enabling conventional oscilloscopes to display and measure in-circuit wave forms that are referenced to high common mode voltages.
The differential probe extends the measurement capability of oscilloscopes in electronic power converters, inverters, motor speed controls,
switch mode power supplies, and many applications. The probe is in compliance with IEC-61010-031 CAT III, Pollution Degree 2.

* a. The supplied voltage must be less than 10V and greater than 4.5V, or the probe could be damaged or will not operate 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.
** (Input Voltage)The differential and common mode voltage range is the operating voltage range and the absolute voltage range is the safety voltage range.
