7. Инструкция по эксплуатации
This section details how to operate the XH300 to generate desired signals.
7.1 Включение/выключение питания
Once the power supply is connected, the device will automatically power on, and the LED display will illuminate.
7.2 Signal Type Selection
The device can output either magnetoelectric or Hall signals. Use the dedicated button (often labeled 'SET' or a specific toggle) to switch between these two signal types. The corresponding LED indicator (Hall or Magnetoelectric) will light up.
7.3 Frequency Range Selection
The XH300 offers 9 frequency ranges. Use the 'Up' and 'Down' buttons to cycle through the available frequency ranges. The selected range will be displayed on the LED screen.
- 01: 2Hz - 1KHz
- 02: 2Hz - 2KHz
- 03: 2Hz - 3KHz
- 04: 2Hz - 4KHz
- 05: 2Hz - 5KHz
- 06: 2Hz - 6KHz
