  • Page 32 Hot-Plug is supported in this mode, you can simply replug a new cable for fast selecting. Double click the middle key to exit this mode, after that, don't forget to swich off the PD tester switch.

  • Page 33: Cable Resistance

    Cable Resistance The meter can measure the resistance of the MicroUSB cable & USB-A 2 Type-C cable, and provides a program for 4-line cable resistance test. The meter can also evaluate the resistance of the Type-C 2 Type-C cable. A load-free mode brings more convinience.

  • Page 34: Normal Mode

    • Normal mode The procedure of the normal mode is : 1. Connect the meter to the adapter by the USB-A male port. Then plug-in a constant- current load(>500mA) into the USB-A female port. 2. Disconnect the meter. 3. Reconnect the meter with an A-C cable or a MicroUSB cable, then plug-in the same load in step1, the cable resistance will be shown on the screen.
  • Page 35 Since the negative line and positive line usually have the same dimension and material, the result is reliable in the most cases,. The procedure of the bypass mode is : 1. Connect the meter to the adapter by the USB-A male port. Then plug-in a constant-current load(>500mA) into the USB-A female port.
  • Page 36 Then the resistance comes out, this mode is hot-plug supported. Diagram Painting A double click on the home screen will make the system into diagram painting mode:...
  • Page 37 In this mode, clicks on the middle key can toggle the diagram from D+D- voltage and voltage-current. Double click the middle key can exit this mode back to home screen. You can adjust the sample rate by scrolling the key to the left & right, available sample rates are 1fps, 2fps, 4fps, 10fps, 20fps, 30fps, 50fps,100fps.

  • Page 38: Idle Clock

    Idle Clock This device can be used as a digital clock when it's not in use. Refer "Menu" chapter for the related settings.
  • Page 39 Offline Recording The device consists "Offline Recording" feature, it can record the voltage & current in a period for further analysis. Right click at the home page to enter offline recording menu:...
  • Page 40 • Curve Create New After clicking "Curve Create New" option, the screen will turn to above. Current voltage, current and power is shown on the top-left side, point No., space condition, sample rate is shown in green, summary data is shown in white.
  • Page 41 You can manually pause or continue the record by clicking the "Pause/GoOn" button, stop the record by clicking "Stop" button. For automatic record starting/stopping, look up in "Curve Settings" section.
  • Page 42 After a record, the device will enter record summary screen. It shows the starting time of the record, record length, sample rate and summary data including capacity, energy and lasting time. You can view the record diagram by click "Diagram" button, but it is more recommended to view the chart on PC.

  • Page 43: Curve Settings

    • Curve Settings The device can store at most 4 curves, each curve can store data of 3750 points. For example, if the sample rate is 2 seconds/ point, each curve can store the data in 3750 * 2 = 7500 seconds, which is about 2 hours. You can set a lower sample rate to get a longer duration, but this will lead the curve to lose some details.
  • Page 44 The automatic behavior of the device can be set by "Start Threshold" and "Stop Threshold". When the current is lower than the start threshold, the device is in standby mode and won't record any data. Once the current is above the start threshold, record starts. Setting the start threshold to 0mA means the record always starts after created.
