While heating a led (O1 or A1) in the left upper corner of the ”display” will flash.
Flashing will be intermittent and regular as the unit reaches the set temperature.
Follow steps 5 thru 8 for every calibration point.
For decreasing the temperature the same procedure as described above must be
followed.
To provide provide an optimum use of the TRAQC-3 LL, all control functions are
available through RS232 interface.
With the Tradinco AutoCal Software, the TRAQC-3 series dry block calibrators
communicate with a PC.
This MS Windows based software is completely 'MENU' controlled and allows the
user to program pre-fixed calibration routines and run calibration routines fully
automatically.
The environment (temperature and draught), length and the mass of the probe
may influence the measurement considerably.
If the manufacturer has enabled “pushbutton used for factory settings”, one has
access to a part of a menu structure. Use of this feature is not required; any
change may seriously change the behaviour of the instrument.
4.2
Temperature switch
Connect the temp-switch to the “temperature switch 4mm sockets” and insert the
switch in the boring of the insert.
With the “up and down pushbuttons” the desired temperature can be set between
-30°C and 150°C.
Make sure the louver assembly is not blocked.
Observe at least 20 minutes stabilisation time when the set temperature is
reached, in order to achieve the specified stabilization accuracy.
Adjust or check the temp-switch so that the “switching indicator led” switches at
the desired temperature.
4.3
End of use
Do not switch the instrument off or disconnect the mains lead until the instrument
has reached a temperature between 10 to 30°C.
In order to cool down or heat up down the TRAQC-3 LL, set the set temperature
around room temperature. When a temperature between 10°C and 30°C is
reached, turn off the TRAQC-3 LL
