F.d. = 4 digits divisor , programmable from 1 to 10000. This parameter allows to divide the
number of the input impulses, showing them on the display in an other format. If it programmed

b.t. = Time Base.
This programming allows to select in which time base shows on the display the measure in
input. There are three scales:
1 = Time Base: seconds, measure visualization in seconds (ex. Meters/seconds)
60 = Time Base: minutes, measure visualization in minutes (ex. Liters/minutes)
3600 = Time Base: hours, measure visualization in hours (ex. Bottles/hour)
