inputs from external noise pickup is critical for minimizing measurement errors. Turning on the low pass filter may help
you to filter out the noise and achieve a stable reading.

The accuracy for duty cycle and pulse width measurements is based on a 3 V square wave input to the dc 3
V range. For ac couplings, the duty cycle range can be measured within the range of 10% to 90% for signal
frequencies >20 Hz.
The range of the duty cycle is determined by the frequency of the signal: {10 μs × frequency × 100%} to {[1 – (10
μs × frequency)] × 100%}.
The pulse width (positive or negative) must be >10 μs. The range of the pulse width is determined by the
frequency of the signal.
The accuracy for duty cycle and pulse width measurements is based on a 3 V square wave input to the dc 3 V range.
