1.2 TRAQC-3 LL Description
The use of model TRAQC-3 LL offers a number of great advantages above
alternative methods of temperature calibration, but requires that any
user reads the instruction manual very carefully and is aware of the fact that
high temperature has to be handled with care and only in areas without
hazardous fumes or fire risks and get acquainted with all the facilities offered
by this temperature calibrator.
Accurate temperature measurements can be assured only when it is possible physically
to produce a legitimate basis for establishing traceability to temperature standards.
The TRAQC-3 LL dry block calibrator is a high precision temperature calibrator ranging
from -30°C to 150°C.
By setting the TRAQC-3 LL a series of different temperatures, the inserted sensor/
display/recorder can be calibrated accordingly.
The maximum probe diameter is 25mm and block depth is 145mm.
The TRAQC-3 LL consists of 5 main parts:
The cooling/heating block is cooled by peltier elements and heated with resistance
heating elements.
The instrument is electronically controlled and regulated with 2 push-buttons on
the front panel and indicates the temperature in the display in the front panel.
The temperature is controlled by a precision thermometer (RTD sensor) and an
intelligent closed loop circuit.
The heating/cooling block is completely insulated to further optimise performance.
RS232 communication interface.
The aluminum housing is equipped with a carrying handle. Up to two inserts, insert puller
and insulating tube can be stored inside the housing of the TRAQC-3 LL calibrator
Dimensions are (LxWxH) 399.3x149.3x298mm (399.3x143.3x346mm including
insulation tube) and the weight is approximately 11.5 kg.

2.Important knowledge
The factors which characterize a dry-block oven are:
Accuracy of the display compared to a standard
The stability over time
The axial homogeneity of the block
The boring to boring homogeneity
The European Association of National Metrology Institutes, Euromet CG-13 Guideline
describes this in detail. This paragraph will briefly discuss the parameters above. Please
note that the importance and pit-falls with these parameters are often overlooked. More
important is to specify these parameters correctly in order to know the measurement
uncertainty.
2.1 Accuracy of the display compared to a standard
Usually a dry-well block oven is used in combination with a standard temperature
measuring instrument. A Unit under test (UUT) is in that instance calibrated against the
said standard. Important then is to have a dry well which can hold its temperature very
stable.
2.2 Stability
Is defined as temperature variation as function of time. The Euromet CG-13 guideline
uses a 30 minute interval. This makes clear that a good stability over a long period of
time is actually a good stability.
2.3 The axial homogeneity
Is probably the most important (and forgotten) parameter of a dry-well block calibrator.
If one uses a probe with 5 mm length and measure at intervals the temperature while
pulling out this probe, one can determine the axial gradient. Due to its geometry,
isolation characteristics, the heat loss of the probe etc. the heating bloc is not
homogenise in temperature. Differences in the order of magnitude of degrees of Celsius
are often found. This parameter is very important because usually it is not known how
long a PT100 in a probe is, or at what position, in the probe (or UUT) the PT100 or
Thermocouple is placed. The Euromet CG-13 Guideline mentions a 4 cm homogenise
zone as a kind of a norm.
2.4 The boring to boring homogeneity
Most dry-well block calibrators have an insert with more than one boring. If there is one
boring this boring is usually in the centre. An ideal symmetric situation with internal
heaters elements is then automatically provided. With two borings a symmetrical position
of both borings can be reached if the position is of each boring is at equal distance to the
heating element. A mark of the insert should then be provided. This mark should be
placed in line with the mark on the block. Again this is often overlooked but an important
factor in determining the uncertainty of a calibration. Once one is aware of this issue one
can easily take appropriate counter measures.

4.Operating instructions
4.1 TRAQC-3 LL
Note: Please observe proper grounding of the instrument. Use the supplied power
cord if possible.
Be careful, the top parts around the heat block of the TRAQC-3 LL, especially the
“upper grill”can become hot. Also the air above the instrument heats up. When
operating, be careful not to burn yourself and that the heated air can freely flow
into the room without damaging/ interfering anything.
Place instrument in a way that the ventilation openings on the underside and side
panels of the instrument are not obstructed for proper measurement results.
Connect the power cord to the unit and turn it on.
When the TRTAQC-3 LL starts up, a sequence of different numbers will be shown
in the “display”.
-8888: check all segments of the “display”.
-Prog, then a number: this shows the software revision number,
-XXXX : a code number for manufacturers use only,
-XX: a code number for manufacturers use only,
-Hr XX: The amount of hours the TRAQC-3 LL has been powered, the six
digits after the “Hr” represent the hours up to 99999.9 hrs
-XXXX: see above.
Place the correct insert for the unit under test into the “heat block well”.
To ensure a good calibration, the probe diameter has to be within 0.2mm smaller
than the diameter of the bore in the insert.

User Manual
TRAQC-3 LL
TRAQC-3 LL 12/2018 EN Rev.5
page : 11
Be careful the insert can be very cold or hot, always use the insert grabber.
Place the insulation tube onto the insert.
Never handle the insulation tube when it’s hot. The insulation tube should cool
down to less than 70°C before being placed in “insulation storage hole”. Always
use the insert grabber.
Always place the insulation tube. The passing air can seriously affect the
calibration due to the passing air of the cooling fan onto the, to be calibrated
probe.
Place unit under test (RTD, thermo couple, temp. switch, etc) through the
insulation tube into the insert bore.
It is recommended to use the centre hole for all measurements.
At special request from customers, the pattern of insert holes may differ, a
temperature reference hole may be ordered as a extra option. See also section 2.4
for proper use of the borings in the insert.
With the “up and down pushbuttons”the desired temperature can be set between
ambient -30°C and 150°C.
Make sure the “upper grill” is not blocked.
Set the first calibration/test point.
After 1 second the “display”indicates the actual temperature.
After the unit has reached its set-point the specified accuracy is reached after 5 till
10 minutes.
Observe at least 20 minutes stabilisation time when the set temperature is
reached, in order to achieve the specified stabilization accuracy.

User Manual

TRAQC-3 LL 12/2018 EN Rev.5
page : 12
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

If the “heat block well” is very polluted it can be
cleaned with a brass tube wire brush. After cleaning
flush the “heat block well” with compressed air.
Clean the bore and outside of the insert with a dry
cloth.
If the bore of the heat insert is very polluted it can be cleaned with a brass tube
wire brush. The outside with a brass wire brush. After cleaning flush the bore of
the insert with compressed air and clean the outside with a dry cloth.
If the TRAQC-3 LL is not operated for longer periods or moved, remove the insert from
the “heat block well” and store the insert in one of the two “insert storing holes”.
5.2 Cleaning the fan grille:
On top, the TRAQC-3 LL is fitted with an air grille, “upper grill” via which cooling air
enters the TRAQC-3 LL.
