The frequency output can be congured in once of three ways:
1. Specifying how many pulses per unit, P/U (i.e., 10 pulses per SCF)
2. Specifying how many ow units total per pulse, U/P (i.e., 0.1 SCF per pulse)
3. Specifying a maximum frequency to a dened maximum value of ow rate
All of these approaches are equivalent.
F1 F2 F3 F4
Use P/U (F1) to enter pulse per unit, U/P (F2) for unit per pulse or FEQ (F3) to enter the ow and
maximum frequency to scale the frequency output.
NOTE! When data is entered with any of the three described methods, the other values will
be re-calculated according to the settings.
Entering data in Pulse per Unit
Press P/U (F1) 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 value entered is in pulse
per selected ow unit total (for example, 2 pulses per SCF).
Entering data in Unit per Pulse
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 value entered is in unit per pulse (for example. 0.5 ow unit total per pulse)
Entering data with ow and maximum frequency
Press FEQ (F3) and the following screen will show:
