During the timer operation the prescaler has to be disabled or set to 01,0000.
The prescaler can be used to record quantities, provided that the quantity per
time unit is known and constant.
Example: A volume of 3 liters per second is supplied.
Settings: Time format "seconds", prescaler 3,0000
Display: Supplied volume in liters as a function of time.
The prescaler cannot be used with the time format
HH:MM:SS as it is not applicable in this application
The following modes of timer operation can be selected:
Cumulative measurement following the pulse-width measuring principle
(Cumulative measurement as long as input A is active)
Cumulative measurement following the cycle-duration principle
(Cumulative measurement from rising edge Input A to falling edge of Input A)
Cumulative measurement A=Run, B=Stop (cumulative measurement from rising
edge Input A to rising edge Input B)
Single-pulse measurement following the pulse-width measurement principle
(Measure as long as Input A is active)
Single-pulse measurement following the cycle-duration principle (Measurement
from rising edge Input A to rising edge of Input A)
Single-pulse measurement A=Run, B=Stop (Cumulative measurement from rising
edge Input A to rising edge Input B)
