one switch load Description:
A designed according to the principle of ohm’s law and through the resistor in parallel through a different switch, can produce 3 kinds of resistance of a new USB electronic load resistance discharge, when all the switch opens, is 2.2 ohm/10W, 4.7 ohm/10W, 2 kinds of resistance in parallel at the same time, in 5V voltage almost can produce 3A discharge current.
The actual current size, please according to ohm’s law: I = U/R
Resistor in parallel calculation formula: R=1/(1/R1+1/R2+…+1/Rn)
K1=4.7Ohm/10W , K2=2.2Ohm/10W
Load device is working, winding resistance caused by large current, will produce very, very high temperature, therefore in the process of use, and just use the finished in a short period of time, absolutely can’t human exposure golden metal radiator parts, to avoid the scald!Nor to flammable items contact tester, in order to avoid the fire!In use process must be highly vigilant!
Considering the particularity of heat resistance, the initial use of electricity after a period of time will appear a few white smoke and smell, because outside the paint contains very little moisture, high temperature electric heating, moisture evaporates form the phenomenon of white smoke, produce peculiar smell by high temperature baking paint outside phenomenon, completely disappear after using for a period of time.This phenomenon is inevitable, belongs to the normal situation, do not have to worry about load tester can damage, please be assured that use
Load application:
Can be convenient to test mobile power charging treasure, mobile phone charger, USB power output current is such as to amount to mark, so long as connect USB above.And can do it for mobile power supply and USB power adapter aging test, aging test discharge resistance will be hot, temperature is controlled in 80 ~ 85, please pay attention to prevent hot

two switches load Description:
Brand new and high quality.
It’s normal when welding resistance may occur heated white smoke or odor phenomenon.
New products can freely be switched with a switch, very convenient and easy to use.
USB load resistance, is mainly to do discharge test, if the charger or mobile power supply output current is 2A, load meter power is 5V * 2A = 10W, if the output current is 1A, then the power load is 5V * 1A = 5W.
Switch and usb interface design.
