## Key Features
True RMS AC measurement capability ensures accuracy across varied waveform geometries. Four-wire Kelvin resistance measurement eliminates lead resistance errors in precision applications. Frequency measurement from 3 Hz to 100 kHz supports characterization of power supplies, oscillators, and signal sources. Native thermocouple and RTD support eliminates external conditioning circuits for temperature monitoring.
## Typical Applications
Electrical component verification, circuit troubleshooting, automated production testing, thermal system diagnostics, and frequency characterization in embedded systems and power electronics development.
## Compatibility & Integration
USB 2.0 (Full Speed) connectivity integrates with SCPI-compatible test frameworks and data acquisition platforms. Direct measurement logging to host computers enables time-stamped data analysis and statistical trending without intermediate data translation layers.
