1 in stock


The 4231 is designed to safely analyze floating signals. The built in amplifier scales
and converts the high voltage differential input to a low, voltage single-ended BNC output,
compatible with any oscilloscope. The inputs are useful in measurements of power semiconductor circuits,
robotic drives, NC machines and the latest switching circuits.

* a. The supplied voltage must be less than 12V and greater than 4.4V, or the probe could be damaged or will not operate properly.
b. polarity is “+” inside and “V” 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.
