Product Description Product DescriptionThe Battery Internal Resistance Analyzer, also known as the general-purpose rechargeable battery internal resistance tester, is designed to measure the internal resistance, voltage, and temperature of rechargeable batteries such as lead-acid and lithium batteries. It serves as an instrument to assess the health status of batteries and can also be used for measuring the Equivalent Series Resistance (ESR) parameters of electrolytic capacitors (for reference only). This instrument employs AC 4-terminal testing method to measure battery internal resistance, ensuring accurate measurements unaffected by contact resistance between test leads, terminals, and battery electrodes. It features functions such as data storage, data retrieval, alarms, and automatic shutdown. The device is sophisticated in design, broad in measurement range, high in resolution, easy to operate, portable, accurate, reliable, and stable in performance, with strong anti-interference capabilities. It is indispensable in scenarios such as battery production, battery installation, equipment production, and equipment maintenance.The general-purpose rechargeable battery internal resistance analyzer is controlled by a microprocessor, equipped with a 16-bit ADC internally to accurately detect battery internal resistance, voltage, and temperature. It operates without stopping the UPS system during measurement, using AC low-resistance measurement and noise reduction technology. This allows measurements to be conducted without interrupting the normal operation of the equipment being tested, significantly reducing testing time. Additionally, it includes features such as data storage, bar graph display, data upload to computers, and wireless measurement and data retrieval via Bluetooth connection with smart devices like computers, smartphones, and tablets.Product FeaturesResistance Measurement AccuracyMeasurementMaximum DisplayMaximum ResolutionTesting Accuracy0.000mΩ~3 Ω3.100 Ω1 uΩ±0.5 % Voltage Measurement AccuracyMeasurementMaximum DisplayMaximum ResolutionTesting Accuracy0.000V~70 V±71.00 V1 mV±0.2 % Temperature Measurement AccuracyMeasurementMaximum DisplayMaximum ResolutionTesting Accuracy-10.0oC~60.0oC60.0oC0.1oC±1.0oCDetailed PhotosProduct ParametersFunctionsBattery internal resistance, battery voltage, temperatureAccuracy Assurance for Temperature and Humidity23oC±5oC,Below 75%rhPowerDC 3.7V lithium batteryResistance Resolution1 u ΩVoltage Resolution1 mVTemperature Resolution0.1oCMeasurement RangesInternal Resistance: 0.000 mΩ to 3.100 Ω (4 ranges) Voltage Measurement: 0.000V to ±71.00V (2 ranges) Temperature Measurement: -10.0oC to 60.0oC (single range)Maximum Input VoltageDC 70V (+ measurement terminal to - measurement terminal), no AC input allowedMeasurement MethodInternal Resistance Measurement: 1kHz AC 4-terminal test method, open circuit terminal voltage 3V maxMeasurement Current: 2.0mA to 200mA (varies with range settings)Temperature Measurement: NTC temperature sensor (10KΩ at 26oC)A/D Conversion Method: Successive approximation typeDisplay Update Rate: 5 times per secondResponse Time200msMeasurement TimeApproximately 2 secondsLCD Size70.1mm × 52.6mm / 3.5 inches (320×240 resolution 16-bit color screen)Instrument DimensionsLength × Width × Height 190mm×121mm×51mmUSB InterfaceIncludes USB interface for data storage, upload to computer, and saving for printingBluetooth ConnectionYesHold and Storage FunctionsManual hold and storage, automatic hold and storageMeasurement Judgment FunctionPreset PASS, WARNING, FAIL threshold judgmentsBattery VoltageDisplays 5 levels of battery capacity, alerts for low battery voltage to prompt chargingAuto Power OffAutomatic shutdown after approximately 15 minutes of inactivity (can be disabled in settings)Power Consumption300mA MIN / 500mA MAXWeightInstrument: 480g (including battery)Operating Temperature and Humidity-10oC~40oC;≤80% RHStorage Temperature and Humidity-20oC~60oC;≤70% RHInsulation Resistance≥20MΩ (between circuit and housing at 500V)Withstand VoltageAC 3700V/RMS(between circuit and housing)External Magnetic Field<40A/mExternal Electric Field<1V/mCompliance with Safety StandardsIEC 61010Product DimensionCompany ProfileSimilar RecommendationFAQQ1:Is your company a sales or a manufacturer?
