calculations are explained at the end of this section.)*
SCALING FOR COUNT INDICATION
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 meter to scale or multiply the input pulses by
a scale factor to achieve the desired display units (feet, meters, gallons, etc.)
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.
WHERE:
Desired Display Units: Count display units acquired after pulses that occurred.
Decimal Point Position:
Number of Pulses: Number of pulses required to achieve the desired
