Function
The calibrators of the series TP 28 1300 E are used with dry block function.
Adapter sleeves or calibration inserts that are suitable for the temperature sensors or tem-
perature measuring instruments to be tested are inserted in the calibrator (
§ 4.3
"Preparation of the calibrator").
They give the test specimen a secure fit and ensure optimum heat transfer.
Once all the preparations have been carried out, the calibrator can be switched on (
§ 4.4).
The calibrator heats the metal block to a set temperature between 400 °C and 1.300 °C. Solid
state relays (SSR) are used to control the heating elements. As soon as this temperature has
been reached and is stable, the LED "OUT 1" on the controller signals accordingly. The cali-
bration of the test specimen can now be carried out.
