10.3. Setting up the instrument (example)
Remarks It is an additional example for Chapter 7. Setting-up. It
helps to understand the setting of values through a practical
example. The steps of the whole setting you will find in
Chapter 7. .
Exercise
Setting parameters The task is: temeperature measurement with Pt100 sensor
with 4 wire connection.
A DT4120 xx xx (PS) has an analog output option, output
level 4-20 mA, scaleing: 0 °C ÷ 4 mA, 100 °C ÷ 20 mA.
Limit 1 is active when T > 90 °C, hysteresis: ±0.1 °C.
Leading zeroe’s are disabled.
The DT4120 xx xx (PS) parameter settings:
