Detailed Description
Model: W291855 W291855 resistance of the battery tester, online, accurate, rapid, and convenient diagnostic battery quality equipment. I. OVERVIEW: W291855 resistance of the battery tester is my company independently develop, produce the first high-precision internal battery resistance testing instruments. I will sum up years of battery experts advanced battery technology, combined with large-capacity battery stops working group, as well as the day-to-day maintenance needs, it has developed a high-precision portable resistance tester, the product small size, weight light, easy to carry. The product is "dynamic load DC Law" as a means of on-line measurement of the resistance battery, the battery technology in the large-capacity measurement in the field of the world's leading status. The method used 20 to 70 A discharge current to the battery discharge test moment, in the high noise environment of the battery test, Float voltage on the interference measurement process can be negligible, and therefore be able to accurately measure Float-state batteries resistance. W291855 at the same time can be measured and recorded single battery internal resistance, resistance connection between the battery, the battery voltage monomer. W291855 real-time measurement data storage, and provide different time accurate historical data, and report each cell measuring time, measurement data can be permanently preserved. W291855 comes with RS-232 serial port, the tester can be connected to the data lines through the computer, and then use the "battery data management system" withdraw all measurement data, create data tables, and other forms of monomer column of the report, and use scientific diagnostic model analysis, judgement monomer battery health status and battery capacity. W291855 built-in lithium battery, the battery is fully charged in the case, can be carried out 16 hours of continuous testing. Own wall inserted in the AC charger to work, and can simultaneously charge. The product can be widely used in battery performance rapid detection, battery routine maintenance, installation of the battery acceptance. Second, the functional characteristics: 1. Single voltage: w291855 battery Float in the state of voltage measurement. Measuring range 0 to 16 V, all within the scope of this battery can be measured readings can reach 0.001 V. 2. Single cell resistance: single battery internal resistance of the battery load response of the decision. With a short period of time and the load current, voltage drop can be calculated battery internal resistance. CRM1000 ensure that the method of calculating the Float battery can be measured, can also be measured off-line battery. 3. Battery connection between Resistance: CRM1000 two can be measured by a battery connected to electrical-connection between the resistance, including measurement of resistance and battery connector connecting the column is the contact resistance. 4. High precision, good repeatability: CRM1000 exclude the possibility that electromagnetic interference, the ripple current, parasitic capacitance, and other interference. 5. Automatic selection: CRM1000 can automatically select the appropriate voltage, load resistance and testing time. 6. Operations simple and easy: All Chinese-style operation, ease of maintenance personnel to operate the ordinary batteries. 7. Intelligent procedures: built-in feature of diagnostic systems, automatic calibration system. 6. Data extraction and analysis: CRM1000 through RS-232 serial port to connect to a computer, the use of battery data management system from the test data, extraction and analysis in the form of bar charts or tables show results, we can print test reports , preservation. Third, technical indicators: Project Scope Accuracy Voltage: 0 ~ 16.00V 0.1% of reading ± 1 word Resistance : 0 ~ 60.00m Ω 2% ± 5 μΩ Connecting resistance: 0 ~ 2.000m Ω 0.25 reading ± 2 μΩ Battery capacity All of the above 5Ah battery capacity Power:7.2VDC, 10AH, 16-hour power supply Display: 128 × 64 points (OLED) Size :307mm (W) × 258mm (D) × 122mm (H) Weight: 3.2KG Test results storage capacity: 96 × 32 or 48 × 64 or 24 × 12 × 128 or 256 (Group * section) Other Increase can be configured at the same time measuring 6 2 V single cell 4, testing: 1. Connection of test Link: 1. First air plugs correctly connected with the test instrument; 2. Red folder in the folder measured battery cathode, black folder in the folder tested negative battery, large black folder in the folder tested batteries and a battery connected to the positive (or folder directly to the measured batteries) . 1. Testing process 2. Opened tester, set measurement parameters, select measurement; 3. Good connections tested batteries, press the button measurement; 4. Adjustment test folder connected to a battery tested, the test instrument automatic editing test serial number. 5. Battery data management system: The software and CRM1000 battery internal resistance tester is an integral whole, the use of the software can establish their regional battery pack, batteries and the name of the station name. The software can be downloaded from the internal resistance tester data, the data will be stored in designated locations, and data processing, analysis, a single battery voltage, resistance, resistance connecting the column, forms and data; The software also can be According to the benchmark, measured battery resistance, automatic battery capacity estimate monomer. Users can generate their own needs, according to the circumstances of the report. 1. Battery management: the software can be set up provincial, municipal, sub-stations and the different levels of battery management. Data Processing: battery can provide different test data downloads, generate reports and print measurement parameters can complete all of the software parameters (monomer battery voltage, resistance, the resistance of the connection between the battery) the historical trend analysis, allows users to to form or customized graphics to see history. In graphics, the software also allows users to set threshold, the threshold can be judged whether or not beyond the scope of measurement parameters.
