UNI-T UT-P31 Differential Probe – English Description
Overview
The UNI-T UT-P31 Differential Probe provides a safe and reliable measurement solution for use with oscilloscopes. It converts high differential input voltages (≤1500V Peak) into a low-voltage signal (≤7V) that can be displayed and analyzed on an oscilloscope. With a bandwidth of up to 100MHz, it is ideal for high-power testing, research and development, troubleshooting, and maintenance applications.
The probe's attenuation values are specified for oscilloscopes with a 1MΩ input impedance. When used with a 50Ω terminator, the attenuation factor becomes twice the indicated value.
For extended applications, the UT-P31 can also be used with the PL-10 Impedance Converter, allowing more accurate voltage measurements using a digital multimeter. While a typical oscilloscope offers approximately 1% accuracy, a digital multimeter can provide significantly higher measurement precision.
