3. Example for pulse width:
The pulse width can be set from 0.3ms to 500ms in increments of 1ms. However,
the pulse width should be set to less than 40% of the pulse rate due to the setting
range and counting rate.
If “0” is set, the pulse width automatically will be set to 40% of the pulse rate
(100ms max.)
Example 1

the pulse rate
: 3600(m^/h) / 0.00l(m^) =36000000 pulses/h
=1000pulses/p
the pulse rate for full scale = 1ms
*the pulse width = 1ms x 40% = 0.4ms

the pulse rate for fiill scale = lOOOOOOms
the pulse width(Max.) = lOOOOOOms x 40% = 400000ms
but, the pulse width is 500ms Max.
