There are Four Interfaces: Single Point Measurement, Scan, System Information, Calibration and Calibration
By default, it will enter into the single-point measurement interface

Startup and Shutdown:
Hold down the CTRL key to turn it off by pressing the power button.
In the power-on state, long-press the switch button (more than 2S), and the instrument will shut down after releasing it.

Suggestions to Use:
1. To ensure the accuracy of measurement and calibration, please warm up the instrument for at least 15 minutes.
2. Try to use good-quality RF cables and connectors.
3. The calibration cable marked next may not require calibration and be used directly.
4. The process of testing the cable affects the measurement accuracy. It is recommended not to select too long a test cable as much as possible.
5. Before measurement and calibration, please ensure that you are not in a strong wireless signal to avoid interference due to inaccurate measurement.
6. If you do not understand the impedance measurement itself, you can refer to the instructions and tutorials of the vector network analyzer. The instrument is equivalent to a one-port vector network analysis.
Note: Automatically changed to User Calibration for user convenience. At the same time, in order to ensure the integrity of the calibration, the automatic shutdown function is disabled.
