4 Structure of the temperature calibrator
SIKA Dr.Siebert & Kühn GmbH & Co.KG
Circuit of the integrated measuring instrument
For information on connecting your probe, please refer to the circuit diagram on the
left.
The corresponding settings for the type of probe and the integrated measuring
instrument are described in chapter 5.
The "ext. Ref." connector is used for connecting an external reference. It influences
other displays. The connection and thus display of an external reference is
automatically detected by the calibrator, i.e. the calibrator provides values of the
external reference.
RTD = resistance thermometers
TC = termocouples
mA = mA transmitter
switch = temperature switches
4.5 PC connection, power switch and type label
The calibrator is equipped with a serial interface of the RS-232-C type. This interface operates in two
directions, i.e. data are sent to a superordinate computer for further processing and data are received from a
superordinate computer for programming the calibrator.
Note:
The interfaces of the devices to be connected must comply with IEC 60950.
Interface settings:
9600 Baud, 8 data bits, parity none, 1 stop bit
Connection to a PC
The calibrator is connected to a PC via a commercially available cable, included in the scope of delivery.
