Instructions:1. power adapter: DC12V, with special attention load power supply and power supply must be 2 power supply, cannot be shared;2. the Welcome boot screen; to use & rdquo \that device is normal;3. according to key \the cursor, according to cursor position for addition and subtraction operation, when cursor position in\ I \or\ V \according to addition and subtraction switching voltage and current settings4. the need to force connection, pay attention to positive and negative, try to reverse;5. according to \start\ to start \/ stop electronic load, while screen \ON\ or \FROM\;6. all above settings are automatically saved after power off, the power parameters are back on power down before parameters, but electronic load, regardless of when power is off, the need to manually open7. a load continuous operation of maximum power and room temperature, the ambient temperature is too high and should reduce operating power, if heat sink temperature reaches 87 degrees, the load will automatically reduce power, if temperature continues to rise, continue to reduce power , When core temperature reaches 91 C, to stop working, cooling after manually open8. the load current will according to input voltage automatically adjustments, such as setting 10A, if input voltage is 20V, it will change actual current to 150W \/ 20V = 7.5A (display sets current still sets you up for 10A);9. in need of statistical AH and time before, do not forget to clear, the machine is default has been accumulated, will not be automatically cleared, can only be cleared manuallySupply voltage: DC12V 5%Load mode: constant current loadLoad voltage: 0.5-60VLoad current: 0-10AMaximum power: 150WVoltage reading precision: (0.1% + 0.05% )Current reading precision: (0.2% + 0.1% )Constant current precision: current reading precision + 1dNoise index: 25dD (A)Colour:GreenMaterial:ABSSize:10x14x7cmPackage Contents:1* Capacity TesterOnly above package content, other products are not included.Note: Light and different displays may cause color of item in picture a little different from real thing.
