8 Specifications
Square wave output
The maximum input voltage protection is 30 VDC.
[1]
The positive or negative pulse width must be greater than 50 μs for adjusting the duty cycle or pulse width under different
frequency. Else, the accuracy and range will be different from the definition.
[2]
For signal frequencies greater than 1 kHz, an addition of 0.1% per kHz is added to the accuracy.
