Important Tips:

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

UT8cuaEX9taXXagOFbX2

High-Definition LCD and LCM resolution of 128 * 64 = 8190 pixel and formation pixel hd display and built-in boot screen, 

The large-scale instrument of the same metal manganese copper low electrical impedance sampling technology, < 2 mR Resistance is almost zero (Diameter : 2.5 mm),Faster charging! Charging time shorter!
 
Advantage:  Low resistance design, use after almost does not affect the charging speed, that is the benefits of manganese bronze pieces ! ! !

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 is put into electricity to hold down the button and let it go, so the current automatic calibration and zeroing, generally when the air temperature is zero or one, so the measurement more accurate, if what questions in the process of use, please contact us first in line with customer service, help you solve thank you!
