6 - OPERATION PROCEDURE
6.1 - Operation description
The PTB600 calibrator consist of an anticorodal block fitted with holes into which the sensors to be calibrated
are inserted.
A heater element heats the block and an electronic μcontroller with Triac output checks and regulates the
temperature.
A fan mounted in the rear side generates a constant air flow that reduces the temperature of the case.
6.2 - Description of instrument
6.2.1 - Thermoregulator
The thermo-regulator (7) is a PID microprocessor, which can be set from 0 to 550°C.(600 for model BA)
DISPLAY UPPER LINE: indication of the temperature measured inside the block.
DISPLAY LOWER LINE: indication of the set point; external probes if selected, setting parameters .
KEY: used to increment (decrement) any numerical parameter. The increment (decrement) speed is
proportional to the time the key remains depressed.
F KEY: allow access to the various parameters (repeatedly press), access to the various phases of
configuration (press F +
).
E KEY: allow confirming the set parameter.
The calibrator is endowed with eight terminals (optional) that can be set as Pt100 or Tc.
6.2.2 - Main switch
The main switch (2) is fitted with a socket for the voltage cable, the main switch and two fuses as for the
following table:
MODEL V230 V110/115
PTB600-TC
PTB600-TS
5A 10A
Note: use only fuses F. 5x20mm. All the electrical part is found below the main switch.
6.2.3 - Carrying handle
The calibrator is fitted with a carrying handle .
6.2.4 - Heating resistance
The resistance (13) is stainless steel made; the max. power is 800W ( 1200W for the ¢65, 230V models)
and it can reach temperatures approaching 600°C.
Bear in mind, however, that constant use at extreme temperatures reduces the life of the resistance itself.
Limit the number of hours at which the resistance is used at maximum temperatures to the time required by
the calibrator in order to prolong the life of the resistance.
