Product function characteristics

1. 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 
2. 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!.
   

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

Function characteristics:

1. 8192 pixels HD display;
   
2. USES the large-scale instrument of the same metal manganese copper low impedance sampling resistance is almost zero (1.5 mm diameter metal manganese bronze material < 5 mR, internal resistance is almost zero)
   
3. Memory power time data such as power;
   
4. The single monitoring shows charging voltage, current, power, power WH,mAH, charging time and other information;
   
5. USB is the copper pin and a low resistance in sampling technology, access after almost does not affect the charging speed;
   
6. Wide voltage from 3.30 V to 33.0 V;
   
7. High current measuring 0.00 A to 5.00 A, also can welding line on its own DIY into 15 A fever table; (avoid USB can successfully large current DIY)
   
8. Low and lower power since the < 0.013 A
