Work Mode:
- PWM Mode:Frequency,Duty cycle
- It is PWM mode when display ‘%’.
- The factory default mode is PWM mode.
- 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.
- 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%.
- Short press button ‘ON’ 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.
- The default factory frequency is 1KHz and the duty cycle is 50%.
- Switch work mode:Keep press button ‘SET’ about 6 second.Then it is enter into PULSE mode if symbol ‘%’ disappear on right.

- Short press button ‘ON’ 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.
- The default factory positive pulse width is 0.5 seconds, and the negative pulse width is 0.5 seconds.
- 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.
- Button P+ and P- are used to set delay time.Set time range is 0.000s~9999s.
- Button N+ and N- are used set the number of pulses.Set range is 1~9999 or Infinite.
- The factory default delay time is 0 seconds, and the number of pulses is infinite (display ‘—-‘).
- Automatic return to pulse interface by press button ‘SET’ for 2 seconds.

- Delay 5s after power ON or press ‘ON’ 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. 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:
Connect to power supply.
Select work mode as following manual.
Short or long press button ‘FREQ+’ or ‘FREQ-‘ to set parameter.
Short or long press button ‘DUTY+’ or ‘DUTY-‘ to set parameter.
Connect to load.
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
Note:
It’s 1-channel signal output signals.
Its maximum output current is 30mA.Therefore it cannot directly drive high-power devices.
Please read use manual and description before use.

PASSION FOR OUR WORK
V***k –
Генератор “валит” фронты на низах и на верхнем интервале. Середина более-менее… Огрчился. Частоту держит стабильно- пульсация на третьем знаке после запятой- ну это и ослик может “глючит”(в пределах погрешности). А duty (или как его там- меандр)чётко регулируется. Для ШИМа наверное ключи надо “собирать”…
A***C –
Mai ricevuto. Denaro rimborsato. (per il rimborso metto la seconda stella)
D***o –
не проверял пока. проверю дополню. экран зацарапан как будто в куче хранили. могли-б пленку наклеить(((( расстроило.
