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.
