4.Set Work Mode:
    1>.There is two work mode so it have two frequency range.
    2>.Normal mode:Frequency range 1Hz~150KHz.Duty cycle range 000%-100%. Duty cycle accuracy 1%.Output amplitude range is DC 1V~24V.
    3>.Precise mode:Frequency range 1Hz~15KHz.Duty cycle range 0.00%-100%.Duty cycle accuracy 0.1%.Output amplitude range is DC 1V~24V.
    4>.Keep press button ‘STOP’ for 5 second to switch to Normal mode and Precise mode.
5.Button description:
    1>.Long press means need keep press for more than 3second.
    2>.Short press button ‘STOP’ to enabled/disabled PWM output.
    3>.Keep press button ‘STOP’ for 2 second to lock parameters and display lock symbol at the same time then these parameters can not be set and avoid misoperation.Press 2 second again to release lock function.
    4>.Keep press button ‘STOP’ for 5 second to switch to Normal mode and Precise mode.
    5>.Short press button ‘SET’ to switch display set parameters for frequency and duty cycle and amplitude.Then press button ‘UP’ and ‘DOWN’ to set parameter value.
    6>.Keep press button ‘SET’ for 2 second to set system parameters for ddn/dup/Fdn/FUP/Adn/AUP/dEF.Then press button ‘UP’ and ‘DOWN’ to set system parameter value.
6.Use steps:
    1>.Connect to power supply.
    2>.Set Normal mode and Precise mode.
    3>.Set parameters for frequency and duty cycle and amplitude.
    4>.Set system parameters for ddn/dup/Fdn/FUP/Adn/AUP/dEF if need set.
    5>.Keep press ‘STOP’ for 2second to lock set parameters.
    6>.Test.
    7>.Press button ‘STOP’ to turn on or off PWM output.
    8>.Remove power and connect load to use module.
7.Application:
    1>.Square wave signal generator, generating square wave signal for experimental development
