Description Overview GAOTek Battery Cell Conductance Tester is a key component of the power system, batteries must be tested and maintained annually, quarterly or even monthly and their test data needs to be analyzed on a regular basis. Practice has proved that there is no correlation between voltage and capacity. The battery conductance or internal resistance tester is a digital storage type multifunctional portable test instrument that quickly and accurately measures the operating state of the battery. The device further tracks the decay trend of the battery and alarms in advance to facilitate engineering and management personnel to handle the discretion. Features High-precision online testing, automatic range conversion, large-capacity data storage Automatically converts the range in the measurement range of 0.000-19990S Can permanently store 999 sets of battery parameters (up to 999 batteries per group), can permanently store 500 sets of battery pack setting parameters Battery capacity test range: 5AH-6000AH 5-in color touch LCD screen, English modular operation Chart display and column chart analysis function Capacity analysis function, which can analyze the battery for excellent, good and bad Oscilloscope function: it can display the highest and lowest voltage and average voltage of the battery in real time, and can calculate the voltage ripple Through the SD interface, the test data is permanently stored on the PC to realize the “medical record” tracking analysis of the battery Powerful data management functions, so that the instrument can be used separately from the computer Enhanced over-voltage protection function makes the instrument work safer and more reliable Self-recovery over-current protection function makes the instrument more convenient to use Use the latest SOC chip to greatly simplify the circuit and improve the reliability of the instrument Support large-capacity lithium battery and external power supply Low voltage indications ensure the test accuracy Small size and light weight Technical Specification Measurement range Conductance: 20 to 19,990 S Internal resistance: 0.000 mΩ to 99.999 mΩ Voltage: 0.000 V to 25 V Minimum measurement resolution Conductance: 1 S Internal resistance: 0.001 mΩ Voltage: 1 mV Measurement Accuracy Conductance: ±0.5% ±6 dgt Internal resistance: ±0.5% ±6 dgt Voltage: ±0.2% ±6 dgt Power Supply 11.1 V, 2400 mAh, rechargeable Lithium battery, can work 8 hours continuously Display 5 in color LCD touch screen Memory 64MB Flash 4G SD card Temperature range 32 °F to 140 °F (0 ℃ to 60 ℃) Dimension 8.66 in x 6.69 in x 2.04 in (220 mm x 170 mm x 52 mm) Weight 2.42 lb (1100 g)
