7. Operating Instructions
This section details how to operate the XH300 to generate desired signals.
7.1 Power On/Off
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
- 07: 2Hz - 7KHz
- 08: 2Hz - 8KHz
- 09: 2Hz - 100Hz
7.4 Crankshaft Position Sensor Signal Simulation
The device has 9 types of gear missing teeth signals and one standard 60+0 signal pre-embedded. These can be selected for crankshaft position sensor simulation.
- Select Signal: Tap the 'SET' key to cycle through the available crankshaft signals (e.g., 58+2, 60+0). The current signal type will be shown on the display.
- Edit CKP Signal: To edit a CKP signal, long-press the 'SET' key. Use the 'Up' and 'Down' buttons to adjust parameters if editable.
7.5 Phase Reversal
Press the 'H/L' button to toggle the phase reversal of the output signal. This is useful for testing sensors that require specific signal phase characteristics.
7.6 Signal Amplitude Adjustment
The output amplitude (peak voltage) of the signal is generally equal to the power supply input. Some models may feature a potentiometer or switch (e.g., 12V/5V) to adjust the output amplitude. Refer to the device's specific markings for this function.
