Since there are more and more personal electric devices, users begin to know how to use devices to test electric appliances, such as USB testers. There are a lot of USB testers on the market, and their functions are more or less missing, which cannot meet everyone's needs. ChargeLAB, an English website focusing on charging, launched according to market demand POWER-Z It is planned to develop the all-purpose portable USB PD tester in a targeted way. At present, it has two products, blue shell color screen POWER-Z FL001、 Black shell OLED screen POWER-Z KM001 This article introduces POWER-Z KM001 USB PD tester has those special functions.
POWER-Z KM001 The size is very small, and the three dimensions are only 62 * 24 * 12mm. There is a 128 * 64 high-speed OLED display screen on the front. The display refresh rate can reach 50Hz (50 display data refreshes per second), and the data capture rate can reach 100 times per second. The overall configuration is black gold, and the POWER-Z logo is printed on the front.
A side end, from left to right, is the MicroUSB interface, menu button, left function key and right function key responsible for HID communication.
From left to right, there are Type-C measurement output port, MicroUSB measurement input port, Type-C measurement input port, plus Type-A male connector and Type-A female connector on both sides, the entire POWER-Z tester has up to 6 data interfaces and 3 buttons, which can meet almost all user needs.
POWER-Z KM001 The PD protocol equipment can be detected and tricked, and the output voltage can be set manually. The professional version POWER-Z is also equipped with the PD2.0 data capture function. The computer connection software can be used to capture PD2.0 communication data through Type-C measurement input and Type-C measurement output. This function is very useful for enterprise R&D engineers to develop/measure products.
The first page of the main screen can display a variety of common data, including current, voltage, power parameters, capacity, energy data, recording time display, channel selection, acquisition speed, etc. with a range bar.
Voltage fluctuation data, voltage vertical axis and current vertical axis will automatically adjust the range expansion display.
By adjusting the acquisition rate, you can even see the output ripple. The acquisition rate can be set to 1 acquisition per second, 10 acquisition per second, 50 acquisition per second, and 100 acquisition per second.
On the D+D-detection monitoring page, you can see the D+D-voltage fluctuation and the fast charging identification mode supported by the equipment.
POWER-Z KM001 The decoy function is also integrated. The QC2.0 decoy mode can select 5V, 9V, 12V. The QC3.0 decoy mode briefly press the function key 200mV to jump, and long press the function key to directly step automatically.
Discharge capacity energy statistics function.
The capacity data group is grouped and stored, and each group can be deleted or paused separately.
Offline recording curve function.
POWER-Z KM001's ultra-high resolution can be used for various purposes, such as determining whether Apple Lightning data cable is an MFi officially certified chip or a counterfeit chip. The standby current of this Lightning data cable has reached 0.0008A, which has exceeded the standby current of MFi chip (0.0004A), so it can be judged that this is a counterfeit chip cable.
After inserting the data cable using the original MFi certified chip, you can see that the standby current display is 0.0004A, which is exactly in line with the standby current (0.0004A) of the MFi chip. It can be judged that this is an authentic MFi certified chip cable.
The wire resistance measurement function page can measure the wire resistance. The measurement result directly displays 214.6m Ω. Grade judgment: Ordinary. Users can easily judge the quality of wire resistance.
Chargerlab has also developed a powerful computer terminal connection APP, which has more complete and detailed functions, and can capture PD2.0 data packets, which is very powerful.
The above figure is a demonstration of power-z's PD packet capturing function.
The domestic channel of Chargerlab POWER-Z KM001 portable USB PD tester was officially opened. On June 20, it was officially launched in Jingdong Mall and Tmall Mall. Domestic users can easily purchase it from multiple channels.
