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
Transparent USB tester：
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 ! ! !

(3.30V~33.0V , 0.00A~5.00A / Max 165W Test ,DIY Welding wires =15A / Max 465W Test)
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!.
Matters needing attention 1)Not very large current and input voltage is negative reverse connection.
Voltage measuring range: 3.33V ~ 33.0 V Resolution precision: 0.01 V Current measuring range: 0.00 ~ 5.00 A & DIY 15A Resolution precision: 0.01 A Power cumulative range: 0 ~ 999999 MWH Resolution precision: 0.001 Wh Cumulative capacity range: 0-99999 mah precision: 0.001 Ah(New features) Power metering range: 0 ~ 299.999 W Resolution precision: 0.001 W Timing maximum time: 999 H 59 M 59 S Resolution precision: 1 S Time to refresh: > 500 ms/time > 500 ms/times Measurement rate: 0.5 times/s 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) Product size: 65 x 24 x 14 mm Since the power flow: < 0.015 A Working temperature: – 10 ~ + 60 ℃ Working humidity: 10 ~ 80 (no doubt) The pressure of work: 80 ~ 106 kpa Specifications: Item size:65 * 24 * 14 mm Net weight: 19g Package weight: 28g Color: Black Display Color: white Packing content: 1 x Digital USB Voltmeter Tester ———————————————————————— 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
