3.2 Function
The function of the calibrator is determined by the calibrator model and the installed insert.
Figure 3 shows an overview of the available inserts. Table 3 shows the compatibility of insert,
calibrator model and function.

3.2.1 Operation Procedure
1. Install a suitable insert into the calibrator, see Section 4.3. Ensure that the insert has a
secure fit to ensure optimum heat transfer to the DUT.
2. Once all preparations have been completed, switch on the calibrator. See Section 4.4.1.
3. Select the relevant function in the calibrator software for the insert. See Section 6.2.3.
Note: The inserts have different characteristics. The calibrator is supplied with a set of
predetermined functions tailored to each insert. These have been determined by the factory
and are write protected. They may be used as a basis to create your own custom functions.
4. The calibrator heats or cools the dry block, or calibration liquid, to the set point temperature.
As soon as the temperature is stable, the DUT can be calibrated.
5. Repeat step 3 for all of the required calibration set points.

INFORMATION
For your safety, manual operation of the calibrator, i.e. direct
starting and staying at a temperature, is not possible.
The testing procedure is always started with a testing task, see Section
3.3. This
ensures that the calibrator is always started with a defined end of test behavior.
See “Behavior at Test End” on page 32.
