RATE ENABLE
Module 2 is the programming for the rate parameters. For maximum input
frequency, Rate Enable should be set to NO when not in use. When set to NO , the
remaining rate parameters are not accessible. The rate value is shown with an
annunciator of “ R ” in the Display Mode.
This selects the decimal point position for the rate display and any setpoint
value assigned to rate. This parameter does not affect rate scaling calculations.

SCALING FOR COUNT INDICATION
The CUB5’s scale factor is factory set to 1, to provide one count on the
display for each pulse that is input to the unit. In many applications, there will
not be a one-to-one correspondence between input pulses and display units.
Therefore, it is necessary for the CUB5 to scale or multiply the input pulses by
a scale factor to achieve the desired display units (feet, meters, gallons, etc.)
The Count Scale Factor Value can range from 00.0001 to 99.9999. It is
important to note that the precision of a counter application cannot be improved
by using a scale factor greater than one. To accomplish greater precision, more
pulse information must be generated per measuring unit. The following formula
is used to calculate the scale factor.
Scale Factor = Desired Display Units x Decimal Point Position
Number of Pulses
WHERE:
Desired Display Units: Count display units acquired after pulses that occurred.
Number of Pulses: Number of pulses required to achieve the desired
display units.
Decimal Point Position:
0 = 1
0.0 = 10
0.00 = 100
0.000 = 1000
0.0000 = 10000
0.00000 = 100000
EXAMPLE: The counter display is used to indicate the total number of feet
used in a process. It is necessary to know the number of pulses for the desired
units to be displayed. The decimal point is selected to show the resolution in
hundredths.
Scale Factor =
Desired Display Units x Decimal Point Position
Number of Pulses
Given that 128 pulses are equal to 1 foot, display total feet with a one-
hundredth resolution.
Scale Factor =
1.00 x 100
128
Scale Factor = 0.007812 x 100
Scale Factor = 0.7812
