To achieve the specified accuracy of the calibrators (
§ 9.1) the temperature
sensor (test specimen) and the adapter sleeve must be matched to one another:
•
The borehole d of the adapter sleeve may be in the temperature range
400…660 °C up to 0.5 mm and in the temperature range of 660 °C…1300 °C
up to 1.0 mm larger than the outer diameter of the test specimen.
•
The measurement element of the test specimen must be located in the ho-
mogeneous temperature zone of the adapter sleeve.
Also observe the "Details of the DKD technical committee "Temperature and
Humidity" for the operation of temperature block calibrators" (
§ 10).
Inserting:
The appropriate adapter sleeve is inserted
into the metal block with the aid of the
sleeve exchange tool.
Removing and cleaning:
Let the calibrator cool before you remove
the adapter sleeve.
Pull the adapter sleeve out of the metal
block with the help of the sleeve exchange tool.
Clean the adapter sleeve and the metal block.
This prevents the adapter sleeve from getting stuck in the metal block.

Switching on, cool down and switching off
IMPORTANT!
Observe the instructions and notes in the previous sections (
§ 4.1).
For reasons of safety, upon switching on the calibrator, the fan runs at the fastest speed. As
soon as the internal reference has measured a safe block temperature, the fan speed is ad-
justed.
Switching on:
Turn on the main switch.
The controller is initialised.
tESt appears in the first line of the display.
The version number e.g. rL 2.2 appears on the second line of the display.
Initialization is completed after approx. 5 seconds; the calibration mode is then automatically
displayed.
The installed heating elements automatically adjust the metal block from the room tempera-
ture to the set temperature set at the controller.
