In 2022, the newly revised version 1278E, this batch of sampling resistors is replaced by 5 milliohms, which can measure those 200w-10A fast charging, continuous 6A peak 10A guarantee, and the internal resistance is also lower, but pay attention to sacrificing a little current accuracy and reading beating, the new firmware current Zero return logic optimization, which can achieve zero input current at either end
The new ZY1278E is on sale, with high-frequency ripple and easier operation.
Note that the nameplate on the back panel is still 1278P, the motherboard is upgraded to 1278E, and the model number is on the side.
The order quantity is large and the production capacity cannot keep up. It is expected to be issued within 3 days. Thank you for your understanding.
The function is more high-frequency ripple than the old version 1278, lower self-consumption, and smoother operation.
Without any decoy trigger function, the charger will not light up if the output meter is no-load, and the output meter will light up when the load is connected, which completely reflects the output situation.
It can be directly plugged into the mobile phone&x27;s tail plug or the C port of the charger to measure the actual charging power. It is easy to operate, highly compatible, and can be measured on both sides.
The 24pin full-pin C male and C female sockets can measure the power consumption of U disk mobile hard disks and even C-port monitors through high-speed USB signals.
Xiaomi 120W, OPPO OnePlus C port fast charging, and any C port charging mobile phone notebook PAD power bank display are fully compatible.
The version of the screen metal shield, the viewing angle is 170 degrees, and the contrast ratio of 2k:1 is better.
The appearance is frosted black and gold-plated, super super super super super super super super super super super super super small, so small it is unimaginable. It is recommended to buy a large watch if the eyes are not good.
Voltage 4-24V, current 0-6.5A bidirectional
The voltage resolution is 10uV6 digits, the current resolution is 10uA6 digits, the accuracy is 0.1% plus or minus 5 digits, the annual variability is 0.1%, and the factory calibration is 0.01%.
Spot using brand new imported INA226
This unit does not have the following functions:
PD3.1: Withstand voltage 48v can measure the latest fast charge Wake up, don&x27;t be cut by leeks, our shop is really too lazy to support 240w to cheat money. PD3.1 has been pushed for a year, right? Is there any device above 1K yuan that supports input from the C port? Apple 140w must be magnetically turned. There is a fatal hardware bug in the C port: CC is shorted to VBUS, the culprit that burned countless switch tail plugs. After USB found this bug, it forced to increase the CC withstand voltage to 25V, but it is still 25V, but the lowest level of PD3.1 is also 28V, repeating the same mistakes? Who is the short circuit burner? Manufacturers are not so aggressive Other PD3.1 cannot be popularized at the end of the article. If you firmly believe that there will be PD3.1-48V, contact me and add 200 yuan to buy 1278H, with a withstand voltage of 80V.
Fast charging deception: wow, you can use this function to detect what protocol liquid the charger supports You don&x27;t know what protocol your charger supports? If you are not clear, I will tell you: Original charger: supports the original protocol, Shanzhai charger: may support the original protocol or a bunch of messy protocols has nothing to do with you; third-party universal charger: basically everything is not compatible. Whether the meter supports or not has a relationship with whether your mobile phone can be fast charged, especially some private fast charging mobile phones. When buying a mobile phone, ask if it supports public fast charging such as QC, PD, PPS, and other private fast charging, even if it is supported by a third party, the speed is meaningless. PD single-line logic, the table supports decoy = the table is a device, which will inevitably affect the actual handshake of the mobile phone, so there is no case of the C table with decoy, which is full of terrible bugs.
Additional power supply: can measure battery voltage liquid This is table C. Do you want to use this meter to measure battery voltage? Will you connect the C port line? Or what garbage BUG table below 4V can not work?
Bluetooth connection: You can copy the display to load the liquid on your phone Your watch has no screen? Think the power consumption is too low? Think the interference is too small?
Measuring line internal resistance: You can measure the internal resistance liquid of the line Would you like to pick me up and see? Even if it is supported, it can only be measured by the voltage drop method.
Super many buttons or scroll wheel: cutting functions are more convenient Let&x27;s not mention the life of the roller, just the voltage, current, power capacity waveform, do you put 5 buttons on it? What about the volume? What if the operation is more complicated? What should I do if it is easy to accidentally touch the button when plugging and unplugging?
Ultra-high-performance CPU: You see, my watch can be refreshed with more than 1 mega FPS with the i912900K Your watch has not been plugged in, why is the power bank out of power? In the USB watch industry, wouldn&x27;t it be better to keep the power consumption as low as possible while ensuring more than enough performance? The lower the power consumption, the higher the accuracy and the lower the heat generation. Do you understand?
High-definition colorful large screen + marquee: how cool, you will be the most beautiful boy in the repair shop when you plug it in I&x27;m sorry I&x27;m not a lamp factory, and the readings are also focused on being eye-catching and easy to read. For others, see the one above.
Gravity Rotation: You can automatically turn to the direction you like Do you think the USB meter is the monitor? Most of the usage scenarios of the USB watch are placed flat on the desktop, which makes the gravity rotation not only unrecognizable but also disruptive. If you accidentally touch it, it will turn to the wrong direction. Looking at the Friendship Watch, you can either turn off the gravity when you get it, or the default setting is off. Yes, to castrate the function is to castrate the gravity first, which can be achieved by the domestic gravity ic of 5 cents. There is also a BUG that the IC is connected in parallel on the I2C bus, which will inevitably cause the bus to be more crowded, such as the problem of invalid gravity response when the bus is busy such as protocol measurement or PD packet capture.
Minimalist operation method, short press to cut function, long press to confirm to execute the white character or cursor function in the upper right corner.
Hidden function: After the screen is black, long press to rotate the display screen, press and hold and then power on to enter the settings.
