Short press the middle button to achieve different functions on different interfaces, and long press to return to the previous menu level.
2.4 Function Description
2.4.1 Main interface
The UT70 USB tester has four main interfaces, and when the main interface can switch states, these four main interfaces can be switched by sliding the left/right buttons.

1. Basic measurement interface
The basic measurement interface is used to display the most basic measurement parameters, including voltage, current, power, operation time, electric quantity and other information. Interface introduction:

1. The type of fast charging protocol currently monitored, if none, it will be displayed as — NA–1
2. The current monitored fast charging voltage, if none, is displayed as – NA–
3. Measure and display the current USB D+voltage value.
4. Measure and display the current USB D-voltage value.
5. The false load conduction icon flashes once for every conduction of the internal false load when the power bank mode is turned on2.
6. Current direction flag, forward current (in to out): →, reverse current (out to in): ←.
7. Monitoring voltage, real-time monitoring voltage value, unit: volt (V).
8. Monitoring current, real-time monitoring current value, unit: ampere (A).
9. Monitoring power, real-time monitoring power value, unit: watt (W).

Note 1: When using protocol monitoring, you need to enable protocol monitoring on the setting interface to monitor the fast charge protocol type, especially when using two C2C lines, you must first enable protocol monitoring in the setting. Due to the variety of fast charging categories, some fast charging protocols have similar characteristics, so the monitored fast charging protocols may have a certain probability ofmisjudgment or identification, and the overall accuracy of judgment is about: PD > QC2 > QC3

BC1.2 > APPLE 2.4A> VOOC > FCP > SCP >AFC > VFCP. It is worth noting that if two CC lines are used, at this time, the HID interface should be connected to power on first to keep the power supply, choose to turn on the monitoring (keep monitoring) to complete the initialization, and then access two C lines and electrical equipment. At the same time, the two CC lines can not be inserted blind, that is, C1 to C1 surface, not C1C2, ifyou can not establish communication, first change any plug on the tester to a surface and try again.
Note 2: The power bank mode only works in the basic measurement interface.
Operating instructions:
Short press: Key to switch to the previous main interface.
Short press the key to switch the upload frequency.
Short press: Key to switch to the next main interface.
2. Waveform display interface
The waveform display interface is used to display the waveform of the current monitored voltage, current, USB D+/D -, etc. Default: voltage + current waveform, as shown in the following figure. Interface introduction:

1. Voltage waveform: The maximum voltage value range displayed in the current waveform diagram is 5.4V, and the current vertical scale can be calculated as 5.4/4≈1.35V/div (cell), and the voltage represented by the display position of the current waveform is further estimated to be 3.72*1.35≈5.00V.
2. Current waveform. The maximum current value that can be displayed in the current waveform diagram is 5.4A, and the current vertical scale can be calculated as 5.5/4≈1.35A/div (cell). It is further estimated that the current represented by the display position of the current waveform is 0.70*1.35≈0.95A.
3. Represents the display rate of the current waveform, which refreshes the display by 50 points in 1 second.
4. The time scale is currently 320mS/div (grid).
5. Waveform type: The color waveform is the voltage waveform.
6. Waveform type: The color waveform is the current waveform.

Operating instructions:
Short press: Key to switch to the previous main interface.
Short press the Key to switch between the types ofwaveforms.
Short press: Key to switch to the next main interface.
3. Data recording interface
The data recording interface is used to record the Ah/Wh flowing from the power supply to the device offline. It supports a maximum of 4 groups of data records (10200 points/group, the default is recorded once every 1 second, the interval can be set). Click the middle key to select the record group first, and then click again to start recording.The electric quantity mAh in the above figure represents the cumulative value of hourly current (mA). If discharged at a current of 1000mA for 1 hour, it is equal to 1000mAh, and 1000mAh is also equal to 1Ah.
Energy mWh represents the accumulated value of hourly voltage (V) multiplied by current (mA). For example, when a 10V output is applied and the load is 1000mA, it is equal to 10W. This means that after 1 hour of discharge, 10000mWh is obtained, which is converted into Wh and converted into 10Wh. If converted into household electricity meter units, it is equivalent to 0.01 kWh, and 1 kWh is equivalent to 1000Wh.
Therefore, this interface can be used to evaluate the battery capacity ofmobile phones, tablets, and charging banks. If the statistics show that a charge consumes 17.251Wh(17251.00mWh), and the operating voltage of the internal lithium battery pack of the mobile phone tablet is 3.7V, the general conversion efficiency can be estimated to be 90% when charging the mobile phone tablet. Then the battery capacity in the mobile phone tablet is about 27.251Wh/3.7V * 0.9 = 4.196Ah.
After the offline data recording starts, you need to import the offline data recording time period curve to the upper computer. Note Only the recorded voltage and current curve data is uploaded for offline data. Wh waveform curve data is not uploaded or (the uploaded data is incorrect). The offline data is saved in CSV file through the host computer, and a correct total value is recorded in the last column ofWh.

1. Dash cable is currently exclusive to OPPO A-port cable, and it is possible that not all OPPO data cables on the market are wired, and if there is no OPPO data cable corresponding to the wire core, it can not be detected. If you suspect that our inspection is inaccurate, you can use a third-party tool to check and compare if possible, or you can send the line or send the line purchase link to us to buy back for comparison and confirmation.
2. When testing, the data cable is connected to the tester’s A port base, and the other end can not connect anything to the test. If you access the charging head at the other end, the test may conflict, resulting in no detection.

4.4 Precautions for monitoring the power or protocol used by third-party devices (such as mobile phones)

1. To first access the HID online power to maintain power supply (some mobile phones and other electrical equipment and the fast charge head in the negotiation of the fast charge agreement may restart the fast charge head without voltage output, so it is necessary to access the HID power supply to keep the tester working), the device to open the monitoring, re-power to choose to maintain monitoring, after the monitoring initialization is completed, and then access the line and equipment。
2. If you access two C lines to monitor, you can’t blind plug, C1 to C1 surface, not C1C2, because there is only one line in the C line for communication, C_IN is C1 communication, C_OUT side should also be connected to C1 communication. If communication cannot be established (trigger fast charge), first change any C-line plug on the tester to another side and try again.
3. Fast charging protocol monitoring is likely to be inaccurate or inaccurate, because there are many types of fast charging protocols and they are similar, we can only constantly increase the accuracy of fast charging protocol monitoring according to actual tests.

4.5 The fast charge protocol detects and triggers exceptions

1. If some fast charge heads keep restarting when detecting and triggering, and cannot complete the detection or triggering normally, you can connect the HID wire to keep the power supply to complete the triggering/detection.
2. Because there are a lot of fast charge heads on the market, we may not test all of them, if it is suspected that the tester did not detect this head has the protocol we determined to support in the baby description, if there are conditions, you can find a third-party tool to detect and compare, or you can send the head or send the purchase link to buy the head for us to compare and confirm, if there are later we test.

4.6 Support description of the fast charge protocol

1. We only support a certain version of the fast charge protocol of some manufacturers, such as OPPO in addition to VOOC, there are SVOOC, we currently only support VOOC detection, trigger retention later support, the maximum voltage and fast charge of this fast charge protocol will be less than SVOOC.
2. In the later stage, what we can support after research, we will also try to increase some private fast charge agreements of different manufacturers as much as possible.

4.7 D+/D- Displays the situation description

1. Common computer USB A port or some charging head, generally there is no fast charge function, and the BC1.2 protocol is generally used by default for external power supply, and the D+/D- voltage will be about 0V at the beginning of access, this is not the tester is broken or not allowed. If these ports use other protocols for external output, the D+/D- voltage will change.

4.8 HID port on the button side

1. The HID on the key side has no measurement function, and is only used to connect thecomputer and identify the upper computer. If only this port is connected, the voltage and current will be infinitely close to 0, and D+/D- will be similarly close to 0.
