✦ 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.
