to 99.9 seconds. To assist in stabilizing an erratic display, increase Lo-Udt for a
display averaging effect.
13. MAXIMUM UPDATE TIME (Hi-Udt)

fixed and is approximately four seconds per display.

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 CUB5 to scale or multiply the input pulses by
a scaling factor to achieve the desired display units (feet, meters, gallons, etc.)
in the internal count register which results in the desired count display value.
The scale factor is a prescaler, which means changing the scale factor does not
change the existing internal count, but only effects the incoming pulse count.
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.

Desired Display Units: Count display units acquired after pulses that occurred.
