9 in 1 QC2.0 3.0 MTK-PE 3.6~32V Digital USB tester DC voltmeter current voltage meter amp voltammeter amperimetro detector load
Original manufacturers direct sales:good news, the product function to upgrade again! Applied more widely and more powerful! Welcome to choose and buy!
Important Tips：
1.When the ambient temperature changes or the outside heat conduction to tester causes the current to not return to zero and the display shows 0.01A or 0.02A or otherwise,Please Hold on the key buttion then insert to USB Charger It can make the current temperature of the ambient current zero calibration,After the zero can more accurate measurements.And when in Zero calibration,the output can not have any load current consumption, so usb tester display 0.00A
2.In order to avoid unnecessary misunderstanding, due to the USB load in the course of use, will be hot, there will be a slight smoke, this normal phenomenon! Do not work for a long time at 3A current, thank you!
3.Work time :Power>0.5W(00:00:00T)
1.Color: Black USB Tester

Product function characteristics
1)High precision three measurements constantan low internal resistance of wide voltage large current of 150 w high power measurement USB watt-hour meter, can be single at the same time monitoring show that the dc voltage, current, power, power, temperature, current time of USB equipment, imported sampling devices, high-definition LCD and LCM resolution of 128 * 64 = 8190 pixel and formation pixel hd display and built-in boot screen, make the content more rich human, through watt-hour meter above keystrokes, you can reset data such as power, time, at the same time, let the playability is higher, and increase the playability safety of battery play test!.2)In this table is three measure and manganese metal copper low rolling-resistance sampling device of wide voltage large current USB watt-hour meter 165 w high power measurement, can be single at the same time monitoring show that the dc voltage, current, power, power, current time of USB equipment, in particular the high-definition LCD and LCM resolution of 128 * 64 = 8190 pixels that shows more clear parameters and built-in welcome boot screen, make the content more rich human, built-in memory can store electricity blackout data such as time, but also through watt-hour meter above keystrokes, you can reset data such as power, time, let the playability is higher, is a production assistant and digital users the ideal equipment
Matters needing attention 1)Not very large current and input voltage is negative reverse connection.2)Pay attention to high temperature and exposure and metal scratch surface shell, etc.This form USES A low-resistance metal sampling device, 3)current amplification coefficient more accurate multiples as higher requirements to the environment, in order to measure more accurate design is obtained by using the fast refresh, so sometimes will be at ambient temperature changes in light phenomenon of zero zero occasional, if you find the occasional light show 0.01 A or 0.02 A, this is normal phenomenon, can also explain this form because you heat conduction on heat devices such as external charger or load makes small errors in this form of internal temperature change device, this time you light some time let the temperature normal temperature will return to 0.00 A current, if found at room temperature can\'t restore to 0.00 A, also can reset to zero by oneself, the method is: when no electricity to hold down the key not to put insert

Voltage Precision evaluation:
Current Precision evaluation:
!!!Announcements!!!1, the 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!
2, 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.
The 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. .You are very lucky.
