1、Power requirements: DC12V voltage (actual voltage 11-14V), current can not be less than 0.5A, otherwise the power supply will display an inappropriate Error. 2、Discharge current: 0.20-9.99A stepper motor 0.1A or 0.01A, maximum error: 0.7%-0.01A. 3、Maximum capacity test error: 0.5A 5%, 2A 5%, 5A and 2% or more offline (terminal) voltage range: 0-20V step 1V or 0.1V. 4、Maximum voltage measurement error: 1% + - 0.02V. 5、Maximum power: 60W super power automatically limits the maximum current (for example, when opening 00A, it can open 9.99A 6V and maximum 20V up to 60W). Features: Power requirements: DC12V voltage (actual voltage 11-14V), current can not be less than 0.5A, otherwise the power supply will display an inappropriate Error. Discharge current: 0.20- 9.99A stepper motor 0.1A or 0.01A, maximum error: 0.7%- 0.01A. Maximum capacity test error: 0.5A 2.5%, 2A 1.5%, 5A and 1.2% or more offline (terminal) voltage range: 1.0- 25.0V step 1V or 0.1V. Maximum voltage measurement error: 1% + - 0.02V. Maximum power: 60W super power automatically limits the maximum current (for example, when opening 3.00A, it can open 9.99A 6V and maximum 20V up to 60W). The highest battery test statistic: 999.9Ah or 9999Wh, the implementation value stops testing (the first value for the person who stopped the condition).
