Victor High-Precision Handheld LCR Meter Series (4080/4082) – 100kHz Continuously Adjustable Frequency, DCR Mode, Dual-Parameter Display & 2.8″ TFT Screen
Price range: $119.99 through $249.99
The 4080 and 4082 series represent a new generation of professional handheld LCR meter instruments, combining laboratory-grade accuracy (0.2% basic precision) with portable convenience for field service, production lines, and R&D laboratories. These versatile meters measure inductance (L) up to 2000H, capacitance (C) up to 20mF, resistance (R) up to 20MΩ, and impedance (Z), with secondary parameters including X, D, Q, Ø, and ESR for comprehensive component characterization. The 4082 model elevates performance with a continuously adjustable test frequency from 100Hz to 100kHz (starting from 1Hz), while the 4080 offers fixed frequencies at 100Hz, 120Hz, 1kHz, 10kHz, 40kHz, and 100kHz. Both models feature a 0.3Vrms/0.6Vrms signal level (0.1Vrms-1.1Vrms adjustable on 4082) and selectable output impedance of 100Ω. As a truly intelligent handheld LCR meter, it includes exclusive DCR mode (4082) for DC resistance measurement of inductors and transformers, internal bias for semiconductor testing, and electrolytic capacitor mode for accurate large-capacitance evaluation. The 2.8-inch TFT color LCD displays primary and secondary parameters simultaneously, with three selectable test speeds (fast/medium/slow) to balance throughput and precision. Auto-ranging, open/short circuit calibration, data hold, and data recording functions simplify daily operation. Powered by a 2600mAh rechargeable lithium battery or via Mini-USB, this lightweight (423g) and compact (190×90×50mm) handheld LCR meter delivers benchtop performance in a handheld form factor, making it an essential tool for engineers, technicians, and hobbyists who demand accuracy, versatility, and portability in component testing.

- Laboratory-Grade Accuracy in a Portable Form Factor
With a basic accuracy of 0.2% (0.3% for 4080), this handheld LCR meter delivers measurement precision that rivals bulky benchtop instruments. The high-resolution 2.8-inch TFT screen provides clear readouts of both primary parameters (L/C/R/Z) and secondary parameters (X/D/Q/Ø/ESR) simultaneously, allowing you to fully characterize components in a single test. Whether you are sorting SMD capacitors on a production line, verifying inductor Q values in RF circuits, or troubleshooting power supply filter capacitors in the field, the exceptional accuracy ensures reliable decisions. The 4082 model's continuously adjustable frequency from 100Hz to 100kHz (with 1Hz step) enables detailed impedance profiling across the entire audio and switching frequency spectrum – a capability rarely found in any handheld LCR meter at this price point. - Versatile DCR Mode & Internal Bias for Advanced Testing (4082 Exclusive)
The 4082 model introduces a dedicated DCR (Direct Current Resistance) mode, which measures the DC resistance of inductors and transformers without the influence of inductive reactance – critical for evaluating copper losses and winding quality. This feature is invaluable for power supply designers, motor manufacturers, and transformer repair technicians. Additionally, the internal bias function allows you to apply a DC bias voltage during capacitance or inductance measurements, simulating real operating conditions for semiconductors, varactors, and electrolytic capacitors. As a comprehensive handheld LCR meter, the 4082 goes beyond basic LCR testing, providing engineering insights that help you understand component behavior under actual circuit stresses. - Electrolytic Capacitor Mode for Large-Capacitance Testing
Large electrolytic capacitors present unique measurement challenges due to their high capacitance values and equivalent series resistance (ESR). This handheld LCR meter includes a specialized electrolytic capacitor mode that optimizes test parameters for accurate readings on capacitors up to 20mF. Combined with the ESR measurement capability, you can quickly identify aging or failing capacitors in switch-mode power supplies, motor drives, and audio equipment – a common failure point that causes ripple, noise, and system instability. The ability to test large capacitors in the field without a benchtop LCR bridge saves downtime and reduces maintenance costs. - Dual-Parameter Display & Three Selectable Test Speeds
The large 2.8-inch TFT LCD shows main and sub-parameters on the same screen, eliminating the need for mode switching and reducing test time. For example, you can simultaneously view capacitance (C) and dissipation factor (D) or inductance (L) and quality factor (Q) – essential for pass/fail sorting and component matching. Three test speeds – Fast (4 readings/s) for high-throughput production, Medium (2 readings/s) for balanced performance, and Slow (1 reading/s) for maximum accuracy – let you tailor the handheld LCR meter to your specific application. Fast mode boosts productivity in inspection lines, while Slow mode ensures precise measurements for calibration and reference work. - Auto-Ranging, Open/Short Calibration & Data Management
The auto-ranging function intelligently selects the optimal measurement range, making operation effortless even for less experienced users. For critical measurements, the open and short circuit calibration features eliminate parasitic impedance from test leads and fixtures, ensuring that the displayed value reflects only the component under test. This calibration is particularly important when measuring low-value resistors or small-capacitance components. The data hold function freezes readings for documentation, while the data record feature stores multiple measurements for later analysis. This intelligent handheld LCR meter also supports Mini-USB communication (virtual serial port) for remote data logging and PC-based analysis, bridging the gap between portable field testing and laboratory data management. - Continuous Frequency Sweep (4082) for Comprehensive Impedance Analysis
The 4082 model's ability to continuously adjust test frequency from 100Hz to 100kHz (starting from 1Hz) is a game-changer for impedance spectroscopy. You can sweep frequencies to observe how a component's impedance changes with frequency – identifying self-resonant points in inductors, dielectric absorption in capacitors, or frequency-dependent ESR in electrolytics. This feature is typically reserved for expensive benchtop impedance analyzers, but this handheld LCR meter puts it in the palm of your hand. Combined with the 0.1Vrms–1.1Vrms adjustable signal level, you can also test components at different drive levels to detect voltage-dependent capacitance (common in MLCCs and varactors). - Built-in Safety Features: Capacitor Discharge Warning
Testing charged capacitors can damage the meter and injure the user. This handheld LCR meter displays a prominent "DISCHARGE CAPACITOR BEFORE TESTING" warning on the screen, reminding you to safely discharge capacitors before connecting them to the test terminals. The five-terminal (HCUR/HPOT/LPOT/LCUR/GUARD) configuration supports both three-terminal and five-terminal measurements, reducing lead inductance and improving accuracy for low-impedance components. The GUARD terminal effectively shields against external noise, ensuring stable readings even in electrically noisy industrial environments. - Long Battery Life, USB Charging & Portable Design
Powered by a 2600mAh rechargeable lithium battery, this handheld LCR meter offers extended operation for full-day field testing without frequent recharging. The Mini-USB port serves dual purposes – charging the battery and providing a communication link to your PC. Weighing just 423g and measuring 190×90×50mm, it fits comfortably in your hand or tool bag, making it ideal for on-site troubleshooting, inventory sorting, and educational demonstrations. The rugged construction and intuitive button layout (including dedicated keys for FREQ, RANGE, LEVEL, SPEED, and COMPARE) ensure quick, one-handed operation. Whether you are a quality control engineer, an electronics repair specialist, or a university lecturer, this handheld LCR meter delivers professional-grade performance with unmatched portability and value.
