Battery Voltage Internal Resistance Tester
Overview
FNIRSI "HRM-10" is our company's first handheld high-precision attery internal resistance meter. It is a true four-wire measurement internal resistance meter, designed with precision, convenient to carry. The device can automatically test internal resistance and voltage values simultaneously, with measurement results displayed on the screen. Users can also manually adjust the voltage and resistance range. The product features a sorting mode, automatically filtering the good and bad batteries based on user-set thresholds. It also supports historical records and exporting data tables of historical measurements.
Features
- Voltage Internal Resistance Battery Tester: FNIRSI battery tester can automatically test internal resistance and voltage value at the same time. The measured value can be used to determine whether the battery quality has decreased.
- TFT HD Color Display: The display adopts advanced color HD technology and excellent layout. Compared with traditional monochrome displays, it can present test results more clearly and vividly, greatly enhancing the user's measurement experience.
- Accurate Measurement: Adopts customized Kelvin four-wire connection method to avoid wire and contact resistance and improve measurement accuracy. Users can also manually adjust the voltage and resistance range.
- Wide Application Range: Suitable for all kinds of batteries. Car battery tester, household battery. It supports historical records and export data tables of historical measurements. View 8 sets of voltage and resistance values to batch select batteries.
- LED Display Handheld Meter: The resistance measurement range is up to 200Ω and the voltage measurement range is up to 100 V. The device must not be used with a DC voltage higher than 100V. Do not apply AC voltage under any circumstances.

Easy Claims Process
It is not a long complicated process to file and resolve a claim. Be warned--sometimes they will want you to send back the defective or damaged product, even if it's not worth the shipping ---they pay. Overall worth the investment though.

Asurion you made the return process simple
Working with Asurion was an easy process. My previously covered milk frother stopped working, and they fully refunded it with no questions asked. All I had to do was ship the broken item back to them and they sent me a gift card. To cover the initial cost, no questions asked. The refund process was a very simple and painless.
