.
• Press ENTER.
The pulse output can be operated in 2 modes:
• Select a mode.
• Press ENTER.
• Enter the pulse value.
The unit of measurement will be displayed according to the actual physical quantity.
When the counted physical quantity reaches the entered pulse value, a pulse will be transmitted.
• Press ENTER.

description
Continuous pulses
• output of a continuous pulse sequence, reproducing the temporal behavior of the corresponding flow
quantity (volumetric flow rate, mass flow rate), at simultaneous totalizing
• smallest pulse break = pulse width at max. pulse rate (pulse width is constant)
Burst pulses
• output of a discontinuous pulse sequence, reproducing the behavior of the totalizer
• several pulses can arise intermittently with equidistant pulse distances (pulse break = pulse width)
• serves exclusively for totalizing
• max. pulse rate (depends on the pulse width that is constant)
