PRESYS │ Instruments TA-1200PLAB The meaning of clearance between the sensor and the respective well should be understood in a subjective way and common sense is very important. Thus, the sensor should enter the insert well (both completely clean) in such a way to stay snugly enough so that it cannot move or swing inside but it should not enter by force to get jammed. -

The measurement zone of this equipment is 10 cm from the bottom of the insert outwards. The TA-1200PLAB calibrator has three independent controls acting on three heating zones to guarantee any desired temperature profile on your isothermal block. All measuring and differential thermocouples used in the instrument are of noble metals to ensure the best temporal stability. - Page 30 PRESYS Instruments TA-1200PLAB Choose the test set points. As default, the tested temperatures in factory are: 300, 600, 900 and 1100 °C. If necessary, you can prioritize other points or ranges for gradient adjustment. Let the two standard thermocouples touching the bottom of the well. Set the test temperature and wait until it stabilizes (at least one hour).

- Page 32 PRESYS Instruments TA-1200PLAB Fig. 20 - Gradient adjustment Note that because the differential thermocouples BOTTOM and TOP are far from the test thermocouples inserted in the insert, the ratio of setpoint changes to the error produced in the gradient is not one-to-one, but must be searched by repetitive execution of this procedure until reach the desired gradient.
