Method of working:
Adapter sleeves or calibration inserts that are suitable for the temperature sensors or
temperature 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 or cools the metal block or calibration liquid to the set temperature. As
soon as this temperature has been reached and is stable, the calibration of the test specimen
can be carried out.
Then, the next test point is approached or the testing procedure is ended.

Data interface (S versions)
The S version is equipped with a serial communication interface RS485. It is possible to
connect a PC, a level converter or a network via this interface.
The utilized software protocol is a MODBUS-RTU protocol, which is used in numerous
market-available monitoring programs. A separate document for the protocol can be
supplied on request.
The transfer rate (baud rate) is factory set to 9600 baud. Other transfer rates
are available on request.
The 5-pole socket is provided with two connections, A and B, which have to be
connected to the respective sockets of the PC, the level converter or the
network.
