Task:
The task is to measure four temperatures in the production hall by using a K-type
thermocouple. If all temperatures are greater than the preset value of
140 ° C
, in a separate
channel (alarm condition) the inscription
-HI-
is to be displayed, in other cases
-LO-
is
displayed. All the logical channels and the channel with the temperature alarm condition will
be displayed in one window in the values mode.
Solution:
Before measuring temperature the thermocouple sensors should be connected to the
device. An example of the connection is shown in
