White for the regular edition, support for voltage measurement range 3 ~ 12V, higher than 9.99V can not display ten digits, less than 10V for use;
Black high-pressure version, support for voltage measurement range 3 ~ 15V, 15V or less can be normal, for less than 15V use.
Both just support different voltage, all other functions exactly the same








1, the product features:
Simultaneous display of voltage and current and mAH data for easy viewing
MAH mobile power output can be detected
Save multiple sets of test data, power-down save function
It does not affect the data transfer
Higher accuracy, the current parameters of the basic will not bounce
USB and MicroUSB port male double take power, can detect MicroUSB line quality
Current sampling 25 milliohms, smaller loss
With precision current calibration function, the current higher accuracy (calibrated okay when shipped)
2, the performance parameters:
Supply voltage: Normal Edition 3-12V, 3-15V high-voltage version
Voltage Resolution: 0.01V
Test Current: 0.05A-3.50A
Current Resolution: 0.01A
Capacity range: 0-19999mAH
Accuracy: ± 1%
Line loss: 0.1 Euro
Test content: battery voltage, current, discharge capacity (total of 10 sets of data)
3, Features:
3.1, the measured voltage and current:
USB male plug in the USB charger, mobile phones and other equipment female plug, direct readout voltage and current parameters.
3.2, MicroUSB line quality measurement:
Female plug cell phones and other equipment, first with the native male plug USB charger, keep in mind the voltage, then the machine MicroUSB MicroUSB cable into the hole Remember voltage from a USB charger, MicroUSB line voltage smaller the better the quality gap .
3.3, measuring mobile power output capacity and efficiency:
This machine is connected first mobile power, mobile power turn on, press the button until the capacity of the data to zero, repeatedly charged until moving into the phone no electricity supply is automatically shut down. The next show is the capacity mAH mobile power output when opening the machine. Note that this mAH smaller than the nominal mAH output 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 a set of data.
3.5, the data is cleared:
Press and hold the button for 3 seconds or more, then the data for when the group is cleared.
4. Application examples:
4.1, the test phone, tablet, etc. with the electrical mobile power charging voltage and current:
Detector USB male plug in the USB charger, female insert phone, tablet, mobile power equipment, read current and voltage directly.
