block with one hole into which the sensors to be calibrated are inserted. The capacity of the fluid
tank is 500 cm³.
The Peler defices and an electronic microcontroller checks and regulates the temperature. Liquid
srring is ensured by a magnec system. A grid, to prevent the inserted probes from stopping its
operaon protects the srrer. A speed adjustment system is supplied, to ensure the best
homogeneous condion, according to the type of used fluid.
A fan, mounted in the bo om side, generates a constant air flow that reduces the temperature of
the case.
5.2.1 Thermoregulator
The thermo regulator (7) is a PID microprocessor which can be set from -12 to +125°C (resp.
+140°C). The first display line shows the measured value while the second display line displays the
input Set Point value.
Fur further specificaons and methods of use, see chapter 9 concerning the thermoregulator.
5.2.2 Main switch
The main switch (2) is found on the front of the instrument. It is fi ed with a socket for the voltage
calble, a main switch and one fuse (2.5 A for model at 230 VAC).
Note: use only fuses F. 5 x 20 mm. All the electrical part is found below the main switch.
5.2.3 Carrying handle
The temperature calibrator is fi ed with a carrying handle.
5.2.4 Liquid container
The capacity of the container is about 500 cm³.
Follow the instrucons of chapter 3.1.5 to fill the container with the suitable calibraon liquid. The
magnec srrer inside the container makes the temperature of the liquid homogeneous in order
to have the best performance. A metallic grid protects the magnec srrer.
5.2.5 Internal reference probe
The temperature sensor used for the reading and thermoregulaon is a Pt 100 resistance
thermometer. The probe is inserted directly into the aluminium container.
5.3 Operaon
The temperature calibrator can only be used correctly if the user has a good
knowledge of its basics.
Before starng with the calibraon, follow the installaon procedures.
