1. Refer to Primary pages on page 26 and navigate to
page 5: IO .
2. Use the [

] and [

] keys to highlight frequency/totals
and press the [

] key to confirm your choice.
3. Use the [

] and [

] keys to highlight either linked (90°)
or independent . Then, press the [

] key twice to confirm
your selection or press the [

] key to cancel and return
to the previous screen.
NOTE: If you select linked, both outputs will be set up the
same, except they will be 90° out of phase. If you select
independent, each output is set up separately.
4. Based on your selection in the previous step, complete
one of the following steps:
a. If you selected
linked (90°), freq/total # 1 is highlighted
on the next screen. Press the [

] key to confirm the
selection or press the [

] key to cancel and return to
the previous screen.
b. If you selected independent , use the [

] and [

] keys
to highlight the desired output on the next screen.
Then, press the [

] key to confirm your selection or
press the [

] key to cancel and return to the previous
screen.
The meter can support both a frequency output or a totalizer
output, even at the same time on independent outputs.
While both function in similar manners, one may be more
appropriate over the other depending on the application.
The frequency output can be programmed for virtually
any meter parameter, with the most common selected as
volumetric flow rate. The totalizer output can only be set to
discrete units of volume or time.
The maximum frequency the meter can deliver is 10kHz
through a continuous pulse train that is linearly proportional
to the minimum and maximum frequency output
settings (base and span) scaled to the minimum and
maximum output parameter values. See section 3.6.2.2 for
programming steps.
The totalizer output can deliver a pulse per unit volume (or
time) at a minimum pulse width of 1ms. This minimum works
out to a maximum pulse train frequency of 500Hz. Care
must be exercised when setting the units/pulse and the
pulse width values so the pulse outputs is not overwhelmed.
The totalizer output will only generate pulses when the
totalize gate digital input sees an open circuit. The totalizer
will not generate pulses when this input is shorted.
5. Use the [

] and [

] keys to highlight and configure each
of the following options:
a. If you selected
freq/tot status , use the [

] and [

]
keys to highlight the desired option (off or on). Then,
press the [
 ] key twice to confirm your selection or
press the [

] key to cancel and return to the previous
screen.
b. If you selected mode , use the [

] and [

] keys to
highlight the desired option ( frequency or totalizer ).
Then, press the [
 ] key twice to confirm your selection
or press the [

] key to cancel and return to the
previous screen.
c. If you selected drive ctl , use the [

] and [

] keys to
highlight the desired option ( Open drain or push-pull ).
Then, press the [
 ] key twice to confirm your selection
or press the [

] key to cancel and return to the
previous screen.
6. When you have finished, press the [

] key until you
return to measurement view.
