Frequency setting range:

To select the frequency range, briefly press the ‘FREQ+’ or ‘FREQ-‘ button in the normal operating mode to enter the settings interface. The frequency range will automatically switch. Pay attention to the position of the decimal point when the button is pressed.

• Display ‘XXX’: No decimal point. The minimum frequency is 1Hz. The frequency range is 1Hz~999Hz.
• Display ‘X.XX’: The decimal point is the penultimate digit. The minimum frequency is 0.01KHz. The frequency range is 1.00KHz~9.99KHz.
• Display ‘XX.X’: The decimal point is the third-to-last digit. The minimum frequency is 0.1KHz. The frequency range is 10.0KHz~99.9KHz.
• Display ‘X.X.X’: The decimal point is fully illuminated. The minimum frequency is 1KHz. The frequency range is 1KHz~150KHz. For example:
• Display ‘100’ indicates a PWM output frequency of 100Hz.
• Display ‘1.01’ indicates a PWM output frequency of 1.01KHz.
• Display ‘54.1’ indicates a PWM output frequency of 54.1KHz.
• Display ‘1.2.4’ indicates a PWM output frequency of 124KHz.

Duty cycle setting range:

To select the duty cycle, briefly press the ‘DUTY+’ or ‘DUTY-‘ button in the normal operating mode to enter the settings interface. The duty cycle range will automatically switch. The duty cycle range is 0.00%-100%.

 

Usage steps:

5. Connect to a power supply.
6. Press the ‘FREQ+’ or ‘FREQ-‘ button briefly or for a longer duration to set the frequency.
7. Press the ‘DUTY+’ or ‘DUTY-‘ button briefly or for a longer duration to set the duty cycle.
8. Connect to the load.
9. UART communication and parameter settings: The system supports UART data upload and parameter setting functions (TTL level). UART settings: 9600, 8, 1.

 

Set PWM frequency:

• ‘F101’: Set the frequency to 101Hz. ‘101’ can be replaced with values ranging from 001 to 999.
• ‘F1.05’: Set the frequency to 1.05KHz. ‘1.05’ can be replaced with values ranging from 1.00 to 9.99.
• ‘F10.5’: Set the frequency to 10.5KHz. ‘10.5’ can be replaced with values ranging from 10.0 to 99.9.
• ‘F1.0.5’: Set the frequency to 105KHz. ‘1.0.5’ can be replaced with values ranging from 1.0.0 to 1.5.0.

Set PWM duty cycle:

• ‘DXXX’: Set the duty cycle to XXX. ‘XXX’ can range from 000 to 100. For example, ‘D051’ sets the PWM duty cycle to 51%.

3. Read set parameters: Send the command ‘read’ to retrieve the parameters.
4. Return values:

• ‘DOWN’: Set successful.
• ‘FALL’: Set failed.
