Pulse Measurement Function

This mode measures the following times of the pulse input in the function start input terminal.
• ON width
• OFF width
• From the rising edge of the pulse to the rising edge of the next pulse
• From the falling edge of the pulse to the falling edge of the next pulse
When the next pulse is measured, the measured value is written over the previous value.
