Example 2 :
Measured value
= temperature
Max temperature = 75°C
Min temperature = -25°C
Max frequency = 1000 Hz

To set up example 1, proceed as follows :
Begin from measuring mode.
The frequency output will allow flows to be registered up to 1.3 times the maximum value.
(Note : for mass flow and volume flow, all flows are assumed positive).
The absolute maximum output frequency is 1300 Hz so the Max. Value allowed for Fct. 3.4.2. is
1000 Hz allowing for the 1.3 x over-range. See Figure 35 for the frequency output characteristics
of examples 1 and 2.
NOTE:
The frequency output has a duty cycle of 50% for a frequency range > 1Hz. For a frequency
range < 1Hz, the duty cycle is not 50%.
