Range A displays resistance values for the temperature range of 0 to 50 degrees C, range B displays resistance values for the temperature range of 50 to
100 degrees C.
Read-out examples:
-
30 degrees C is in range A and corresponds to a resistance of 1.5 to 2.0 kohms
-
80 degrees C is in range B and corresponds to a resistance of 275 to 375 Ohms
If specified value is not obtained:
-
