core strengths
Easy to Operate
The instrument is equipped with a high-end full-touch LCD display.
Precise Measurement
The built-in variable-frequency power supply module provides the measurement output power, with a selectable frequency of 45 Hz or 55 Hz, and utilizes digital filtering technology.
Powerful Processing Capability
It utilizes a professional DSP (Digital Signal Processor) to enhance the instrument's computational processing capabilities.
Full-Process Intelligent Measurement and Control
The instrument can automatically determine the impedance of the current loop and adjust the output current of the frequency-modulated power supply accordingly (maximum output current: 5A) without requiring manual intervention.
