Press
NEXT (F1)
to cycle through output options until you have the selection for
"OUT=Pulse" and press
OK (F4).
The pulse output scaling can be configured by specifying how many flow units total
per pulse, U/P (e.g., 10 SCF per pulse). The pulse output provides a 500 millisecond
pulse when the specified flow total is measured. The maximum frequency of the pulse
output is 1 Hz.

Use
U/P (F2)
for unit per pulse scaling of the pulse alarm output. Use
FEQ (F3)
to view
the maximum pulse output frequency and calculated maximum flow rate.
NOTE: When data pulse scaling is entered, the maxmimum flow rate will be re-
calculated according to the settings.
Entering Data in Unit per Pulse:
From the Pulse/alarm Output Menu, press
U/P (F2)
and the following screen will show:
F1 F2 F3 F4
Press
CHG (F1)
to change the setting and then
OK (F4)
to accept entry.
The scaling value entered is in units per pulse (i.e. 10 flow units total per pulse).
The pulse scaling can be set to 1, 10, 100 or 1000 units per pulse. The pulse output
provides a 500 millisecond pulse when the specified flow total is measured. The
maximum frequency setting of the pulse output is 1 Hz.
Viewing the Maximum Frequency and Flow Rate:
From the Pulse/alarm Output Menu on p. 45, press
FEQ (F3)
and the following
screen will show:
F1 F2 F3 F4
Maximum pulse rate (frequency) is set to 1 Hz.
