What the HRM-10 Does

The FNIRSI HRM-10 is a handheld battery tester that measures voltage and internal resistance simultaneously. It uses a Kelvin four-wire connection with the supplied kelvin clip test line to minimise lead and contact resistance. Results appear on a TFT HD colour display, and the unit stores up to eight sets of readings for later review or data export.

Who It Suits and Who Should Look Elsewhere

Technicians and hobbyists who need quick health checks on lead-acid, lithium or other chemistries up to 100 V will find the range adequate. Buyers who require AC voltage measurement or DC testing above 100 V cannot use this instrument safely. It also lacks the higher resistance ranges needed for specialised industrial cell analysis.

Checks Before Ordering

Verify that every battery you intend to test stays within the 100 V DC maximum and 200 Ω resistance span. Confirm you can work with the supplied kelvin clip leads and that a colour TFT readout meets your visibility needs. The tester is battery powered, so ensure spare cells are available for extended sessions.

Questions about this item

Does the HRM-10 require any external power source or cable to operate?

No, the tester is battery-powered and ships with a date cable and kelvin clip test line for immediate connection.

Will the HRM-10 give reliable readings if I keep using my existing multimeter probes instead of the supplied kelvin clips?

The unit uses a customised four-wire kelvin method to eliminate lead and contact resistance; swapping to standard probes will reduce accuracy.

After connecting a cell, how do I confirm the HRM-10 is measuring correctly?

The TFT colour screen shows both voltage (up to 100 V) and internal resistance (up to 200 Ω) simultaneously, and stores eight historical records for verification.
