Testing process / Calibration
CAUTION! Risk of burns!
The calibrator can become very hot when in operation. Touching hot parts can result in
serious injuries.
Never touch the metal block, the tank, the adapter sleeve or the test specimen at
temperatures above 35 °C or below 10 °C.
Allow the calibrator to cool before you remove the test specimen, clean the tank,
change the adapter sleeve or the calibration insert or switch off the machine.
6.1
Testing temperature sensors
A separate temperature measuring instrument connected to the test specimen is required to
test the temperature sensors
By comparing the temperature displayed at the external measuring instrument with the
reference temperature it is possible to assess the status of the test specimen. Remember
that the test specimen requires a short period of time until it absorbs the temperature of the
metal block or liquid bath.
The internal references are set to normal when operating the micro-bath, the dry block and
the infrared function; the selector switch should be turned to int. Ref.
In the case of the surface function, an external reference is used. Please connect it to the
mini-DIN socket and turn the selector switch to ext. Reference.
CAUTION! Incorrect results!
It is not possible to calibrate earthed thermal elements, because the heating block is
earthed and any measurement would produce incorrect results.
6.2
Testing process
Before the testing process:
Before the start of the testing process, check whether
the instructions regarding the installation site and the operational position have been
complied with (
§ 4.1).
the electrical connections have been made correctly (
§ 4.2).
the correct measuring insert has been selected for the testing process (
§ 4.3).
the test specimen is securely fixed in the calibrator.
the calibrator has sufficient structural stability.
