Overview
Oscilloscope users are often faced with the need to make measurements between two voltages, both of which are not at earth ground. Differential probes are designed to allow earth grounded oscilloscopes to make safe, accurate floating measurement between these two points. The CT4447 Series probes convert these floating signals to low-voltage ground-referenced signals that can be displayed safely on any ground-referenced oscilloscope.
Compatible with oscilloscopes (with 1 MΩ input) from all major manufacturers, the probes can be powered by batteries (included), a universal mains adapter (included), or by the oscilloscope, if USB equipped.
The probe series is cTUVus certified to IEC 61010-031: 2015, for user safety and confidence.
Available with NIST Calibration as CT4447-#-NISTCAL
