COUNT SCALER
Calculating the Count Scale Factor
The count scale factor is used to convert the incoming count
pulses to the desired unit of measure to be displayed (feet,
gallons, etc.) or to correct for a known amount of error (wheel
wear, viscosity, etc.). This scaler has six digits available
with a fixed decimal point.
Count Scaler Range: 0.0001 to 99.9999
Count Scaler (CS) Formula:
C S =
D P F
P P I
where:
DPF is the decimal point factor corresponding to the de-
sired decimal point location.

XXXXXX
= 1
XXX.XXX = 1,000
XXXXX.X = 10
XX.XXXX = 10,000
XXXX.XX = 100
PPI is the number of pulses per item from the sensor.
Example 1: A sensor produces 20 pulses per inch of ma-
terial travel. Calculate the count scaler required to indicate
material used in whole inches (XXXXXX).
C S =
1
20
= 0.05000
Example 2: An encoder produces 120 pulses per foot.
Calculate the count scaler required to indicate material
usage in 1/100’s of feet (XXXX.XX).
C S =
100
120
= 0.8333
(Select the XXXX.XX position on the totalizer decimal point
menu).
Programming Count Scale Factor
The first screen in the program mode is used to enter the
count scale factor:
Durant
®
RST
The far right digit will be flashing. Press the
RST
key until
reaching the desired digit value.
Note: Pressing and holding the
RST
key will cause the
numbers to autoscroll.
Next press the
key to move the flashing digit one
place to the left. Change this digit to the desired value with
the
RST
key.Repeat this process until all digits are set
correctly.
(Setting the count scale factor to 0.0000 will allow scaling
by 100 in the Courier Series.)
Programming Decimal Point
The second screen is used to enter the decimal point dis-
play on the totalizer screen. Press and hold the
key
and then press the
RST
key to move from screen one to
screen two.

Press the
RST
key to move the decimal point to the de-
sired position.
Programming Offset Value
Programming an offset value allows the counter to reset to
a value other than zero. The offset may be up to six digits.
The offset cannot be a negative number.
The third screen in the program mode is used to enter the
offset value.
