About this item MULTIFUNCTIONAL BATTERY CAPACITY TESTER - Simple and versatile electronic load. Greater cooling redundancy, more suitable for long hours. Multifunctional, it can also be used to test the battery. Automated and well-assembled AC adapter test module assembly AUTO MEMORY: The automatic memory function, with all parameters, is very suitable for automated assembly of the AC adapter test module. AC adapter. p> DISCHARGE CURRENT - Discharge current: 0.20-9.99A in 0.1A or 0.01A steps, maximum discharge current error: 0.7%- 0.01A, maximum capacity test error: 0.5A. HIGHEST POWER AND BATTERY TEST STATISTICS - Max Power: 60W super power automatically limits the maximum current (eg , up to 60W when can open 9.99A 6V and 20V maximum at only 3.00A open). Highest battery test status: 999.9Ah or 9999Wh, value obtained during shutdown test (first value for those in shutdown condition) FAN CONTROL - intelligent fan control fan (depending on whether the heatsink fan can be continuously variable automatic temperature) abnormal voltage protection.
