Precise mode:Frequency range 1Hz 15KHz.Duty cycle range 0.00-100porciento.Duty cycle accuracy 0.1 porciento.
Enter the settings interface when short press rotary switch in the normal running status to select frequency range.Rotary potentiometer to set frequency value.
Keep press rotary switch for 10 second to switch Normal mode and Precise mode.
Keep press for 5 second to locking parameters to protect the parameters from being modified.
Pay attention to the position where the decimal point moves when rotary potentiometer..
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, The minimum frequency is 0.01KHz.The frequency range is 1.00KHz 9.99KHz.
Display 'XX.X'.The decimal point is the third last,The minimum frequency is 0.1KHz.The frequency range is 10.0KHz 99.9KHz.
Display 'X.X.X'.The decimal point is fully lit,The minimum frequency is 1KHz.The frequency range is 1KHz 150KHz.
For example: Display '100' means PWM output frequency is 100Hz; Display '1.91' means PWM output frequency is 1.91KHz; Display '52.1' means PWM output frequency is 52.1KHz; Display '1.3.4' means PWM output frequency is 134KHz; Duty cycle set range: Short press potentiometer to select set duty cycle and rotary potentiometer to set duty cycle value.
Use Steps:
Connect to power supply;
Press rotary switch for 10 second to switch Normal mode and Precise mode;
Short press rotary switch to set frequency and change value by rotating switch;
Press rotary switch for 2 second to set duty cycle;
Keep press for 5 second to lock set parameters;
Test;
Press button 'ON/OFF' to turn on or off PWM output;
Remove power and connect load to use module.
Application: Square wave signal generator, generating square wave signal for experimental development; Used to generate a square wave signal that controls the motor driver; Generate adjustable pulses for use by the MCU; Dimmer; Speed governor.
