Overview
The Fnirsi HRM‑10 is a compact, handheld meter designed to measure both battery voltage (up to ±100 V DC) and internal resistance (0–200 Ω) with high precision
Key Features
- Voltage range: 0 to ±100 V DC (auto and 1 V/10 V/100 V ranges)
- Resistance range: 0 Ω to 200 Ω (auto, 20 mΩ to 200 Ω scales)
- True Kelvin 4‑wire connector with 1 kHz AC test signal for milliohm-level precision
- Pass/Fail mode with threshold settings and data storage/export
- USB‑C port for charging, and CSV data transfer
Use Cases
Battery health testing:
Internal resistance increases as batteries age. A high resistance reading—even if voltage looks okay—can mean the battery is no longer reliable under load.
User Notes
The Kelvin‑lead clamps must not touch each other when measuring, to ensure correct readings
