A generation of white is a normal version, support voltage measurement range of 3 ~ 12V, higher than 9.99V can not display ten digits, suitable for use within 10V
Generation white QC2.0 high voltage version, support voltage measurement range 4~30V, normal display within 30V, suitable for use within 30V
Second-generation Guangxin QC2.0 high-voltage version, support voltage measurement range 4 ~ 20V, 20V can be normal display, suitable for use within 20V
The two generations only have different support voltages, and other functions are basically the same.
1, product features:
Simultaneous display of voltage, current, and mAH data for easy viewing
Can detect mobile power output mAH
Multiple test data storage, power-down save function
Does not affect data transmission
High precision, current parameters will not jump
USB male and Micro USB ports take power twice to detect the quality of MicroUSB cable
Current sampling 25 milliohms, less loss
With current calibration function, higher current accuracy (already calibrated when shipped)
2, performance parameters:
Support voltage: Normal Edition 3-12V, QC2.0 High Pressure Edition 4-30V
Voltage resolution: 0.01V
Test current: 0.05A-3A, 0.05A-3.5A
Current resolution: 0.01A
Capacity range: 0-19999mAH
Accuracy: plus or minus 1%
Line loss: about 0.1 ohms
Test content: battery voltage, current, and discharge capacity (a total of 10 sets of data)
3, function introduction:
3.1, measuring voltage and current:
USB male inserts the USB charger, the female seat inserts the handset and so on the equipment, reads out the voltage electric current parameter directly.
3.2, measuring MicroUSB line quality:
Insert female mobile phone and other devices, first use the male plug into the USB charger, remember the voltage, and then use the MicroUSB cable to insert the USB charger into the MicroUSB port to remember the voltage, the smaller the voltage gap, the better the quality of the MicroUSB cable. .
3.3, measuring mobile power output capacity and efficiency:
First connect the unit to a mobile power source, turn on the mobile power, press and hold the button until the capacity data is zero, insert the phone and charge it repeatedly until the mobile power is turned off automatically. The next time you turn on this unit, the display capacity is the mAH of the mobile power output. Note that this mAH is much smaller than the nominal mAH, the output mAH* output voltage is 5V/battery mAH* battery voltage is 3.7V = mobile power efficiency.
3.4, data switching:
Click the button to switch to the next set of data, double-click the button to switch to the previous set of data.
3.5, data clearing:
Press and hold the button for more than 3 seconds to clear the group data.







二代广鑫达QC2.0高压版介绍:






下面是老化电阻介绍
USB负载测试器开关切换1A/2A放电
因为电阻误差5%,所以对精度要求高的朋友请绕道。

老化电阻的作用:
第一,可以快速帮移动电源放电测试容量,
第二,可以测试充电器移动电源电压和电流达不达标。
1、该负载器工作时,绕线电阻因通过大电流,必然会产生非常非常高的温度,因此在使用过程中、以及刚使用完毕的短时间内,万万不可以人体接触绕线电阻,以免被烫伤!也不可让易燃物品接触测试器,以免发生火灾!总之使用过程中务必高度警惕!
2、考虑到绕绕电阻的特殊性,在初次使用通电一段时间后会出现少许白烟和异味的现象,是因外漆还含有极少量水分,通电高温发热,水分蒸发形成白烟现象,外漆受到高温烘烤产生异味现象,经过使用一段时间后完全消失。此现象必然会出现,属于正常情况,不必担心负载测试器会损坏,请放心使用。
3.结合本店销售的USB电压电流检测仪来进行测试,就更加直观了,可以看到测试过程中的电压和电流情况。
