## Summary description

The Fnirsi HRM-10 is an internal battery resistance meter designed to measure DC internal resistance with 0.001 Ω resolution. Intended for use with batteries around 1000 mAh capacity, it provides precise resistance readings to assess cell condition and performance. Suitable for hobbyists, technicians and quality control; helps diagnose aging, capacity loss and contact issues.

## Long description

The FNIRSI HRM-10 internal resistance meter is a handheld instrument for assessing battery condition by measuring DC voltage and internal resistance with high resolution. Designed for service and workshop use, it displays results on a TFT HD color screen, stores measurements in internal memory and supports data export to a computer. The meter accepts a wide range of cell types and includes cables and a USB-C charging lead for portable operation.
Advantages
The device uses a four-wire measurement method to reduce the influence of lead and contact resistance and provides reliable readings down to low milliohm values. It offers automatic range selection and dedicated resistance ranges, a sorting function with up to eight threshold sets for quick classification of cells, and a data retention feature that keeps results visible on the display. Built-in rechargeable battery and automatic shutdown extend operating time and improve safety. The housing is made of impact-resistant ABS with anti-slip silicone elements and an integrated stand for comfortable, stable use.
Suitable for
Service centers and electronics workshops
Battery quality control and batch testing
Repair and diagnostics of mobile devices and power tools
Hobbyists and technicians testing 18650, LiPo, button and other cells

How to use
Connect the included measuring leads to the meter and to the battery terminals following polarity markings. Power on the unit and select the appropriate voltage or resistance range or leave it in AUTO. Place the leads so contacts are secure, then start the measurement; results for internal resistance and voltage appear on the TFT display. Use the sorting function to compare readings against stored thresholds and consult measurement history or export data to a connected computer for further analysis. Recharge the device via the USB-C port when the internal battery is low.
Usage recommendations
For repeatable results, ensure clean, tight contacts and allow batteries to rest after charging or heavy discharge before measuring. Use the four-wire leads supplied and enable user calibration if precise baseline adjustment is required. Avoid operating outside the specified temperature and humidity ranges.
