ZY1276: 0.01mAh current resolution. The USB Type C power delivery decoy monitoring capture trigger detection, QC2.0, QC3.0, FCP, AFC, VOOC, DASH, fast charge trigger detection, deception, senior enthusiasts recommend USB test artifact.
USB2.0 interface, with almost full function fast charge trigger detection function, higher current resolution, USB Type C PD adapter can be measured.
Accelerated charging:
  • Plug in computer USB port or non-original USB charger, automatically change the charging identification signal to Original charger, So that the phone is believed to plug into the original charger to speed up charging. Note that this function does not change the output voltage, does not support the ordinary charger to QC2.0 charger, and can not enlarge the output current.
Charger type:
  • Can be inserted into the unknown USB port or mobile power USB port, detection of this USB port specific charging identification signal, easy to identify what mobile phones are available for recharging. When using this feature, it is recommended not to pick up your cell phone, or your cell phone will interfere the identification.
Safety monitor:
  • When the input voltage is too high or too low, the temperature is too high, the output current is too large or too small to maintain the set time, it will activate the USB safety monitoring and protection function, cut off the output to prevent accidents. Can be used for mobile phone charging at night, completely filled with power; protection of voltage and current input not causing damage to the mobile phone charger adapter is disconnected from overheating; stop charging. If you want to resume the output after protection, please long press the button at D+D- voltage to restore the output.
D+D- voltage:
  • That is, the data line voltage, based on this voltage, can distinguish most charger types. You can refer to this voltage to assist in determining the USB port charge identification mode.
Plastic shell:
  • A plastic shell version of dust, anti - entry, good performance, not touch the circuit, it is not easy to interfere with circuit work. PCB frame version without shell, but the 3 board structure of the core circuit protection is also very good, better heat dissipation.
  • Divided into USB3.0 and USB2.0, USB3.0 down compatible with USB2.0, USB3.0 can be used to test the USB3.0 device operating current, USB2.0 interface is more suitable for testing common charger and USB2.0 device operating current.
  • Enter the supported voltage range, it is recommended to work within the nominal value, if less than the nominal value may not work, higher than the nominal value, it will low precision, or even burned.
Electric current:
  • Input support current range, it is recommended to work within the nominal value, greater than 3A can also be normal display, but USB can not withstand large current, may burn USB port. The circuit board sampling resistor supports continuous 6A. If larger current is needed, the external sampling resistor can be changed to support the 20A.
  • Resolving power:
  • The change of voltage or current capacity value, the smaller the resolution on behalf of the higher resolution of voltage and current capacity change more subtle.
  • The percentage of reading accuracy and reading range last beat. The smaller the percentage, the higher the accuracy, the smaller the range of the beat and the more stable the readings are.
Line loss:
  • Contains current sampling loss and USB contact resistance loss. The smaller the value, the smaller the voltage loss after representing the flow through the USB table.
Ampere hour capacity:
  • Ampere per hour, 1A current maintained for 1 hours, then 1Ah, 1Ah=1000mAh, the domestic mobile power and battery capacity units commonly used. Battery capacity and mobile power capacity are commonly used.
Watt hour capacity:
  • Watt per hour, 1W power maintenance for 1 hours is 1Wh, 1000Wh=1 degrees of electricity, compared to Ah expression is more accurate, so the world general. Because the power = voltage x current, so the Ah* voltage =Wh. This parameter is more accurate and convenient to measure the power supply. It can also measure the efficiency of the charger according to the energy meter.
Charging time:
  • When the charging current is larger than the set of trickle shielding current, the time begins to go. Using this function, you can measure the time required for the device to be filled. It can also be used to accumulate the hours of equipment work.
  • The temperature of the built-in chip, if no load, no heating, the readings approximate ambient air temperature.
  • At present, all models are high cost FRAM ferroelectric memory, one billion similar to the infinite number of erasing and writing life, so as to ensure the preservation of a second volume, 300 years is not bad romance.
Static power consumption:
  • The default brightness lights up the screen after the USB meter consumes the current. The machine uses a 32 bit processor + external ADC, all styles are a new low power consumption as low as 2-2.5mAh off screen, arbitrary input voltage is 2-2.5mA, if used to measure the mobile power, regardless of whether how much voltage fast charge per hour, more 2.5mAh can be simple and accurate.
  • Line measuring function:
  • With constant current source, it can detect the internal resistance of the data wire, line loss, voltage drop and so on. The player chooses the higher quality data line.
USB Type C PD test:
  • You can use USB with 2 double headed Type-C lines to test PowerDelivery, the default PD charger does not output and must be connected to the device to output, so the individual insertion table is generally not lit. If access to the Type-C device is not lit, insert any Type-C plug inserted into the USB table and insert it again.
Bluetooth serial function:
  • You can send the test data even on a computer or mobile phone and draw a curve on a computer or cell phone. Host computer development, and can only use the serial assistant +excel drawing temporarily, Note that Bluetooth can not be used to upgrade USB tables, and can only be upgraded with stlink.
  • Computer-side serial port logging software: http://pan.baidu.com/s/1hrpij6O password: jrg2
  • Android phone serial port record software: http://pan.baidu.com/s/1hrJ6hve password: nixq
  • Voltage range: 3.5-24V, limit voltage 28V
  • Voltage resolution: 0.01mV (18bit)
  • Current range: average plus and minus 0-5A, can integrate the instantaneous current 24A (continuous more than 5A, USB port can not bear)
  • Current resolution: 0.01mA (0.15mA or so, 18bit)
  • Capacity range: 0-999999Ah 0-999999Wh

ZY1276 does not include a Bluetooth serial function
The measurements it makes appear fine. However it lacks the Bluetooth serial function to log the data.
