RC3563 battery internal resistance tester, true four-wire AC internal resistance sorter Lead-acid lithium battery UPS test.It supports serial ports and computer software.The battery internal resistance tester can measure the internal resistance and voltage of the battery at the same time. It adopts a Kelvin four-wire test clip, which can better avoid the influence of contact resistance and wire resistance, and can perform more accurate measurements.This product adopts intelligent control, LCD display, and implanted Kalman filter mathematical algorithm. It has the advantages of high precision, high efficiency, low cost, light weight, energy saving and environmental protection. Built-in 1000mAh lithium battery, 5V charging, Android mobile phone charger can be used, very convenient.This product is widely used in various battery production, maintenance, testing, scientific research laboratories and other occasions. It can also be used to measure the AC resistance of capacitors and low-resistance high-precision resistance.Parameters:Test parameters:AC resistance, DC voltageMeasurement accuracy:Resistance:0.5%Voltage:0.5%Measuring range:Resistance:0.001mohm ~ 200ohmVoltage:0.001V ~ 100VDCSignal source;Frequency: AC 1kHzCurrent: 2mohm/20mohm range 50mA; 200mohm/2ohm range 5mA; 20ohm/200ohm range 0.5mARange:6 ranges automatic and manual3 ranges automatic and manualTest speed:5 times/secCorrection: Resistance: each range is individually and manually calibrated without affecting each otherVoltage: each range is individually calibrated manually, and does not affect each otherFactory settings: Save the factory information, one key can restore the factory stateEnergy saving settings: about 10 minutes delay, automatic shutdown without any operationApplicable scope: Cell phone, computer, electric vehicle and other battery maintenance, battery factory inspection and testingShow results:LCD displayPower supply:Built-in lithium battery, using 5V/1A chargerLanguage:English/ChineseColour:yellowMaterial:plasticSize: 166 x 80 x 28mmPackage Contents:1 x RC3563 tester1 x FixtureOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
