Comprehensive Electrical Parameters
Provides D/Q/Z/X/θ/ESR readings to fully characterize component behavior and performance. -
Five Selectable Test Frequencies
Offers professional testing at 100Hz, 120Hz, 1kHz, 10kHz, and 100kHz for different types of components and applications. -
Four RMS Test Levels
Adjustable excitation levels (0.1V / 0.3V / 0.6V / 1.0V) enable optimized measurement stability across various component types. -
Dual Series/Parallel Equivalent Comparison
Simultaneously displays series and parallel equivalent values to minimize parasitic interference and enhance measurement accuracy. -
Full-Band Sweep Mode (100Hz–100kHz)
Provides fast multi-frequency analysis with a single action, enabling detailed characterization of component frequency response. -
Intelligent Sorting with Tolerance Grading
Automatically evaluates components based on preset nominal values and tolerances for rapid OK/NG batch testing. -
Dual-Form Testing: Tweezer Tips + Kelvin Clip
Straight and curved tweezer tips allow easy testing of small components, while the Kelvin clip provides precise four-wire measurement for larger or through-hole components. -
Smart Recognition & Display Functions
Features automatic R/C/L component recognition, dual-parameter display, HOLD/Max/Min, and adjustable system settings. -
Auto-Rotate Orientation
Hand-sensing screen rotation supports both left-handed and right-handed usage for effortless operation. -
Portable Magnetic Design
Includes a magnetic attachment for easy storage and handling, ideal for fast access in field environments. -
1.47" HD Color Display
Offers clear, high-contrast visualization of measurement data for efficient on-site and laboratory usage. -
