Voltage:
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.
Accuracy:
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.
Temperature:
The temperature of the built-in chip, if no load, no heating, the readings approximate ambient air temperature.
Memory:
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 2-2.5mA 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.
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.

Instructions:

Measuring voltage and current:
The USB plug is plugged into any USB port, the mother seat, the handset, and other devices, and the voltage and current parameters are read out directly
Measuring the output capacity and efficiency of mobile power supply:
It is recommended that the resistance be used with a dummy load. The USB male head plug the power supply, the female seat is inserted into the dummy load until the discharge of the full mobile power source is ended and the undervoltage shutdown is performed. The next time you open the machine, the display capacity is the Ah and Wh for the mobile power output.
Calculate battery capacity and efficiency of mobile power supplies:
Ah data X output voltage / battery voltage Efficiency = mobile power battery Ah(output voltage is generally 5V, you can look at the capacity table second screen average voltage, battery voltage is generally 3.7V, efficiency is generally press 85-90%, I store high-end mobile power by 95%), or Wh data / efficiency = battery Wh(so Wh is easier to calculate), battery Wh / battery voltage = battery Ah, Ah / 1000=mAh. If the built-in battery capacity and voltage are known, the efficiency of the mobile power can be calculated:(Ah data X output voltage) / (battery capacity X battery voltage) = mobile power efficiency Or, Wh data / Battery Wh= mobile power efficiency
Measuring the efficiency of the power adapter / charger:
Coordination Electric meter(the goods in your distribution box) and Dummy load to Use. Only after the meter is connected with the measured battery charger, the charger is connected to the output of the USB table and the dummy load, run for a period of time, check the USB table Wh accumulated data, and then check the meter away how much electricity, 1 degrees =1000Wh, USB meter / meter reading efficiency charger change = accurate. (in fact, the number of meters rotary table how much more convenient, the general meter circle is the monogram 0.00x degree)
Measuring data line /USB transfer line / other USB table internal resistance:
Coordination with Dummy load to Use. First of all, the USB table plug power, switch to the line resistance function, and then plug in the precise false load to the required test current (recommended greater than 0.5A less than 2A), reading stable long, press the button record reference voltage, current. Then unplug the USB meter, insert the data line / transit line / other USB table directly into the power supply, then insert the USB meter into the line to be tested, and the dummy load is adjusted to the current as much as the reference current. The line loss resistance of the wire to be tested and the current under test can be read out
Measuring battery capacity:
The use of TP4056 linear charging circuit to no battery charge to full capacity through the table, reading capacity for battery capacity, using this method can probably measured mobile phone charging capacity (as with the USB charger, because the mobile phone is generally not a linear charge, and standby electricity consumption interference)
Measuring micro device current and standby current:
