This product is a USB Type-C meter with various functions. "Taring" is a patented feature of this meter, which allows the meter to accurately display the input or output current (the difference between the two is the meter's own power consumption). Traditional Type-C meters cannot eliminate the impact of their own power consumption on the measurement. These meters will read out as 0mA when powered from one side, and read out their own power consumption when powered from the other side. The user cannot clearly determine whether the current is input current or output current. Long-press the middle key on home panels to enter the main menu, select "Display", and then look down to the "Taring" option. In the "Taring" option, you can choose among "Tare to meet output", "Tare to meet input" and "Show raw readings". When "Tare to meet output" or "Tare to meet input" is set, the meter can display accurate current regardless of the actual power direction. Power Delivery The meter can be connected to the charging port in two ways: direct connection and connection through cable. If the meter is directly connected to the charging port, you can press any of the left and right keys to power the meter on. If the meter is connected to the charging head through a cable, only one of the left and right keys can power on the meter. Press the button on any side and hold it for 3 seconds. If the screen does not light up, press it on the other side to power the meter on. Power-on options After power-on, you have three options; we explain them to you one by one as follows: Keep Power Only The meter won't respond to PD messages; it only pulls down the CC line. With this option, you cannot trigger PD fast charge, but you can start triggering other protocols.Start PD Trigger Pull down the CC line, respond to the PD message, and enter the PD trigger panel. If you want to trigger PD, you need to select this option within a certain period after power-on; otherwise, the communication could time out.Power Off Release the pull-down on the CC line. This option will stop the charging PD trigger panel After entering the PD trigger panel, the meter displays the current and voltage supported by the charging port. The items with "Fix" represent fixed voltage PDOs, and the items with a voltage range represent PPS PDOs with adjustable voltages. Scroll to the left or right to select an item, and then press the middle button to trigger this PDO. For a fixed voltage PDO, after the voltage is triggered, there will be a tick √ on its right side indicating the trigger is successful. For a PPS PDO, click the middle button to enter the PPS trigger panel. On this panel, the upper two readings show the real-time voltage and current, and the lower-left represents the target voltage set by the current protocol communication. The lower-right represents a single adjustment interval. Scroll the key to the left or right to adjust the voltage. Double-click the middle button to return to the previous panel. Current & voltage graphing Double- click the middle button on the home panel to enter the current & voltage graphing panel, and you can see the graph of current and voltage on VBUS with time. The readings in the four corners of the screen display the highest and lowest values in the chart respectively. The real-time value of the current and voltage is displayed in the middle of the upper part of the screen; the time interval of each grid is displayed in the lower part. Read more Current & voltage graphing Double-click the middle button on the home panel to enter the current & voltage graphing panel, and you can see the graph of current and voltage on VBUS with time. The readings in the four corners of the screen display the highest and lowest values in the chart respectively. The real-time value of the current and voltage is displayed in the middle of the upper part of the screen; the time interval of each grid is displayed in the lower part. operating the sampling rate The icon on the upper right side of the panel shows the current status (Paused or not), means it is continuously graphing, and II means the graphing is paused. To pause/continue the graphing, click the middle button. Press the left or right key to adjust the sampling rate, to the left is to decrease, and to the right is to increase. After adjustment, the sampling rate will be briefly displayed on the screen. The maximum sampling rate on this panel is 40 times per second Oscilloscope panel You can click the right button to enter the oscilloscope panel. In the oscilloscope panel, you can see the ripple voltage on VBUS. Values on the left side of the panel display the highest and lowest voltages in the graph respectively(“+50mV” and “-50mV” in this example). The upper middle of the panel displays the peak-to- peak value of the voltage (64mVpp in this example) and the primary component frequency (888kHz in this example); the lower part displays the real-time DC current and voltage on the VBUS. The time interval of each grid is displayed in the lower right corner. E-mark Reader The meter is capable of reading the E-mark information of Type-C cables. To use this feature, power the meter on with the host port, and do not leave anything plugged in on Type-C IN/OUT ports. Afterwards, you plug in one side of the cable to the OUT port (Female port) of the meter and leave the other side floating (As shown below). Finally, press and hold the right button on the home panel to enter the E-mark reader panel. The meter will communicate with the cable and show cable information. Read more Fast charge automatic enumeration Connect the meter to the charger, press and hold the left button on the meter's home panel. The meter will ask whether to perform a fast charge enumeration. Before the enumeration, make sure no load devices (e.g., Smartphones, tablets) remain on the meter. Select "Yes" on the confirmation panel to enter the fast charge automatic enumeration panel, and the meter will automatically detect the available fast-charge protocols. After the detection completes, the upper right corner will prompt "Complete", supported protocols are displayed in green, and the unavailable protocols are displayed in red. Statistics panel On statistics panel, you can read out the statistics as follows: Real-time voltage and currentAccumulated capacityAccumulated energyTotal time of accumulationCurrent data group No.Platform voltageCurrent temperature Statistics related settings Clear group Long-press the middle key on home panels to enter the main menu, select "Data Group". Select "Clear This Group" to clear present group. Select "Clear All Groups" to clear all data groups. Switch group Long-press the middle key on home panels to enter the main menu, select "Switch Group", then choose the group you want to switch into. Accumulation threshold Long-press the middle key on home panels to enter the main menu and select "Threshold" to set the accumulation threshold. The accumulation keeps running when the current is greater than the threshold and stops when the current is smaller than the threshold. A threshold of 0mA means the meter keeps accumulating no matter how small the current is.
