1. Navigate to the mode option on the freq/tot status
screen (see Setting up a frequency/totalizer output
on page 55 ). Then, press the [

] key to confirm
this choice.
2. Use the [

] and [

] keys to highlight the frequency
option. Then, press the [
 ] key twice to confirm your
selection or press the [

] key to cancel and return to the
previous screen.
3. Use the [

] and [

] keys to select and program each of
the six frequency output options. Refer to Table 8 below
for guidance in choosing the appropriate setting for your
application. Also, see Table 9 below for descriptions of
the available options for the error level setting.
4. After programming all of the frequency output options,
press the [
 ] key to accept your new settings or press
the [

] key to keep the previous settings and return to
the previous screen.
Table 8: Frequency output options
Option Description
Units
Choose the channel, parameter and units
to output.
Fbase
Enter the lowest value of the frequency range you
want to output. Typically 0Hz.
Fspan
Enter the highest value of the frequency range
you want to output. max possible 10000Hz.
Value
(min)
Enter the value of the parameter you want
to correspond to the min. value of the
frequency range.
Value
(max)
Enter the value of the parameter you want
to correspond to the max. value of the
frequency range.
Error
level
Choose the output response during an error
condition: force lo, force hi, hold last , or force
value . During a meter error, the chosen error level
will be sent to the frequency output .
Table 9: Frequency output error level options
Option Description
Force low (4 mA) Forces output to Fbase
Force low (20 mA) Forces output to Fspan
Hold value Holds the last “good” reading
Force value
Outputs a user-defined value (from
4 to 20 mA) during an error condition
3.6.2.3 Programming a totalizer output
To program a totalizer output, refer to Figure 64 on page
58 and proceed as follows:
1. Navigate to the mode option on the freq/tot status
screen (see Setting up a frequency/totalizer output
on page 55 ). Then, press the [

] key to confirm this
choice.
2. Use the [

] and [

] keys to highlight the totalizer option.
Then, press the [

] key twice to confirm your selection
or press the [

] key to cancel and return to the previous
screen.
3. Use the [

] and [

] keys to select and program each of
the four totalizer output options. Refer to Table 10 below
for guidance in choosing the appropriate setting for your
application.
4. After programming all of the totalizer output options,
press the [

] key to accept your new settings or press
the [

] key to keep the previous settings and return to
the previous screen.
Table 10: Totalizer output options
Option Description
Units
Choose the channel, parameter and units
to output.
Units/
pulse
Choose how many units of the chosen
parameter are accumulated before a pulse
is output.
Pulse
width
Choose the duration of each pulse that
is output.
NOTE: Make sure the meter is not configured
to output more than one pulse during this time,
as this could lead to missed pulses.
Polarity Choose the negative or positive edge of
the pulse.
