How often is the System Accuracy Test required?

In pyrometry, a System Accuracy Test is an on-site comparison of the furnace temperature vs a separate test thermocouple/instrument to assure the accuracy of the control and recording systems.

It is very important to track the results from these tests since the information changes over time. When conducted properly, this simple test helps the heat treaters to take preventive actions and maintain a reliable temperature system.
