The reason and the solution of the difference between

Hot runner temperature control box display temperature and the actual temperature difference is too large:

1, hot runner temperature controller thermocouple model set up with the degree of thermocouple does not match;

2, hot runner thermocouple short circuit;

3, has set the process bias Pb.

Solution method of temperature and real temperature difference between hot runner temperature control box:

1, set the correct type of hot runner thermocouple;

2, check the line, the correct connection;

3, eliminating the process bias, so that the Pb value is zero.
