White for the regular version, support voltage measurement range of 3 ~ 12V, higher than 9.99V can not display the tens digit, suitable for use within 10V;
Black for the high-pressure version, support for voltage measurement range of 3 ~ 15V, 15V can be displayed within the normal, suitable for use within 15V.
Both only support voltage is different, all other functions are exactly the same
1, product features:
At the same time display voltage and current mAH data for easy viewing
Can detect mobile power output mAH
Multiple test data save, power-down save function
Does not affect the data transfer
Higher accuracy, the basic parameters of the current will not jump
USB male and MicroUSB dual power take, can detect MicroUSB line quality
Current sampling 25 milliohms, less loss
With precision current calibration function, the current accuracy is higher (already calibrated when shipped)
2, the performance parameters:
Support voltage: normal version 3-12V, high voltage version of 3-15V
Voltage resolution: 0.01V
Test current: 0.05A-3.50A
Current resolution: 0.01A
Capacity range: 0-19999mAH
Accuracy: plus or minus 1%
Line loss: 0.1 or so
Test content: battery voltage, current, discharge capacity (a total of 10 sets of data)
3, Features:
3.1, measuring voltage and current:
Plug USB USB plug USB charger, plug the phone plug and other equipment, directly read the voltage and current parameters.
3.2, measuring MicroUSB line quality:
Plug the phone and other equipment, plug the first with the local male plug USB charger, remember the voltage, and then use the MicroUSB line from the USB charger plug into the machine MicroUSB hole to remember the voltage, the smaller the voltage difference MicroUSB line quality better .
3.3, measuring mobile power output capacity and efficiency:
First, the machine connected to the mobile power, open the mobile power, long press the button until the capacity data to zero, insert the phone several times until the mobile power off automatically shut down. The next time you turn on the unit display capacity is the mobile power output mAH. Note that this mAH is much smaller than the nominal mAH and outputs mAH * Output Voltage 5V / Battery mAH * Battery Voltage 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 clear:
Press and hold the key for more than 3 seconds to clear the group data
