display_state()
Set display state on or off.
Usage
display_state(display)Parameters
display: bool- True to turn display on, False to turn it off
reset()
Reset instrument to factory details.
Usage
reset()set_duty()
Set duty cycle.
Usage
set_duty(duty)The pulse width is calculated as width = duty/100*period.
Parameters
duty: float- Duty cycle in percent, valid range is 0.1% to 99.9%
