Instructions for use:
Measuring voltage and current:
USB plug into any USB port, plug the mother cell phone and other equipment, direct reading of the voltage and current parameters
Measurement of mobile power output capacity and efficiency:
It is recommended to use dummy load with resistor, plug the USB plug into the mobile power supply, and insert the dummy load into the socket until the discharged power of the fully charged power supply is finished. The next time you turn on the unit, the display capacity is Ah and Wh for the mobile power output.
ZY1270 Edition uses intelligent identification to speed up the charge:
If not with the official charger, such as the Samsung charger to charge the apple, or through the computer USB charging, charging speed may be slow or even refused to charge, you can plug into the upper USB port to accelerate charging. Note 1A charger is not possible to output 2A, the energy conservation Oh.
Calculation of mobile power battery capacity and efficiency:
Ah data x output voltage ÷ battery voltage ÷ efficiency = mobile power battery Ah (output voltage is generally 5V, you can view the capacity of the second screen, the average voltage, the battery voltage is generally by 3.7V, efficiency generally 85-90% Or high-end mobile power by 95%), or Wh data ÷ efficiency = battery Wh (so measured Wh more simple calculation), battery Wh ÷ battery voltage = battery Ah, Ah ÷ 1000 = mAh. If you know the built-in battery capacity and voltage, you can calculate the mobile power efficiency: (Ah data x output voltage) ÷ (battery capacity x battery voltage) = mobile power efficiency, or Wh data ÷ battery Wh = mobile power efficiency
Measuring the power adapter / charger efficiency:
With the meter (your home distribution box that goods) and false load use. After the meter is only connected to the measured charger, charger output USB table and false load, run for some time, check the USB table accumulated Wh data, and then check the meter to go the number of degrees, 1 kWh = 1000Wh, with USB table reading ÷ Meter reading change = Accurate charger efficiency. (In fact, turn the number of meter wheel turntable more convenient, the general meter will be marked with a circle is 0.00x degrees)
Measured data cable / USB cable / other USB table resistance:
With dummy load use. First of all, insert the power on the USB table, switch to the measuring line resistance function, and then plug in precision dummy load transferred to the required test current (recommended greater than 0.5A less than equal to 2A), read the long press the button to record the reference voltage and current. Then unplug the USB table, with the test data cable / cable / other USB table directly plug the power supply, then the USB table inserted into the measurement line, false load fine-tuning to the current equal to the reference current as much as possible. You can read out the resistance of the wire under test and test current line loss voltage drop
Measuring battery capacity:
Using TP4056 and other linear charging circuit through the capacity table to completely charge the battery fully charged to full capacity readings for the battery capacity, the use of this method can also be measured about the phone charge capacity (as far as possible with the USB cradle, because the phone is generally not Linear charge, and standby power consumption interference)
Measuring the current of small equipment and standby current:
Low 0.1mA high-resolution high-precision current, easy to detect almost all small USB devices operating current / standby current, such as card readers, wireless mouse receiver, Bluetooth or LAN adapter.
Trickle-down function to measure charging time / capacity:
Most of the mobile phone is still full of trickle current, if not shield the capacity will continue to increase the trickle, interference test. When the charge current is less than the set value after setting the trickle screen, the capacity and accumulated charging time will not increase, so the charging time and charge capacity can be measured more accurately. Set to 0 to disable the trickle mask function.
Measurement of electrical equipment to detect the power output capacity of the current waveform:
High-speed current curve drawing (up to 1 second 3 times) can be used to draw electrical equipment after testing the power supply current waveform. Development of self-adaptive electrical equipment essential tool!
