(5) Temperature measuring gauge: The measuring of temperature normally
use platinum resistor. There are two types:
Put the platinum resistor directly into test pack (M pack) when measuring
a. Its temperature;
b. Insert the platinum resistor into the center of four tin electroplated
copper columns, the diameter and height of column is the same 15.2mm.
