Work Mode:
1>.PWM Mode:Frequency,Duty cycle
1.1>.It is PWM mode when display ¡®%¡¯.
1.2>.The factory default mode is PWM mode.
1.3>.Button FREQ+ and FREQ- are used to setting output frequency.User can short press by set value in minimum unit or keep press to continuous setting. Frequency range is 1Hz to 150KHz.
1.4>.Button DUTY+ and DUTY- are used to setting output duty cycle for frequency.User can short press by set value in minimum unit or keep press to continuous setting. Duty cycle range is 0.00% to 100%.
1.5>.Short press button ¡®STOP¡¯ to enabled or disabled output.It is enabled output when display symbol ¡®OUT¡¯ on left.It is disabled output if no display symbol ¡®OUT¡¯ and module will output 0V.
1.6>.The default factory frequency is 1KHz and the duty cycle is 50%.
1.7>.Switch work mode:Keep press button ¡®SET¡¯ about 6 second.The it is enter into PULSE mode if symbol ¡®%¡¯ disappear on right.
2>.PULSE Mode:Pulse width,Delay,Pulse number
2.1>.It is PWM mode without display symbol ¡®%¡¯.
2.2>.Button P+ and P- are used to set time for positive pulse width.Displayed on the first line.Set time range is 0.000s~9999s.
2.3>.Button N+ and N- are used to set time for negative pulse width time.Displayed on the second line.Set time range is 0.000s~9999s.
2.4>.Short press button ¡®STOP¡¯ to enabled or disabled output.It is enabled output when display symbol ¡®OUT¡¯ on left.It is disabled output if no display symbol ¡®OUT¡¯ and module will output 0V.
2.5>.The default factory positive pulse width is 0.5 seconds, and the negative pulse width is 0.5 seconds.
2.6>.Long press button ¡®SET¡¯ for 2 seconds to enter into set the number of pulses and delay time.Screen will display symbol ¡®SET¡¯ at lower left corner.Note:Once in this mode,the output will be disabled and output pulse will be cleared.
2.7>.Button P+ and P- are used to set delay time.Set time range is 0.000s~9999s.
2.8>.Button N+ and N- are used set the number of pulses.Set range is 1~9999 or Infinite.
2.9>.The factory default delay time is 0 seconds, and the number of pulses is infinite (display ¡®----¡¯).
2.10>.Automatic return to pulse interface by press button ¡®SET¡¯ for 2 seconds.
2.11>.Short press button ¡®STOP¡¯ to delay the set time and start output the set number of pulses.
2.12>.It will automatically output 0V if the number of pulses is sent.The output will be disabled and clear pulse numbers if press button ¡®STOP¡¯ during output.
2.13>.The number of set pulses is output each time when module power on.
Practical application:
1>.PWM output 20KHz,60% : Select PWM mode.Set frequency to 20.00 and duty cycle to 060%.
2>.Output turn ON 0.6s,OFF 0.2s,infinite loop : Select PULSE mode.Set positive pulse width to 0.600 and negative pulse width to 0.200.Delay time to 0.000.Number of pulses to ¡®----¡¯.
3>.Delay 5s after power ON or press ¡®STOP¡¯ button.Then output turn ON 0.6s,OFF 0.2s,infinite loop : Select PULSE mode.Set positive pulse width to 0.600 and negative pulse width to 0.200.Delay time to 5.000.Number of pulses to ¡®----¡¯.
4>.Delay 5s after power ON or press ¡®STOP¡¯ button.Then output 10ms high level signal,10ms low level signal,cycle 100 times : Select PULSE mode.Set positive pulse width to 0.010 and negative pulse width to 0.010.Delay time to 5.000.Number of pulses to 0100.
5>.Delay 5s after power ON.Then keep output : Select PULSE mode.Set positive pulse width more than 0(any value) and negative pulse width to 0.000.Delay time to 10.00.Number of pulses to ¡®----¡¯.
Use steps:
1>.Connect to power supply.
2>.Select work mode as following manual.
3>.Short or long press button ¡®FREQ+¡¯ or ¡®FREQ-¡¯ to set parameter.
4>.Short or long press button ¡®DUTY+¡¯ or ¡®DUTY-¡¯ to set parameter.
