TP37 / TP3M Construction, Function and Test Task
Technical changes reserved - 11 -
3Construction, Function and Test Task
3.1 Construction
The calibrator consists of a robust, black-and-red painted steel housing and has a carry-
ing handle at the top .
The front part of the housing holds the electronics of the TP37 / TP3M for controlling the ref-
erence temperature and for the touch screen .
On the front side are the main switch with fuse and mains plug connection , the connection
for the external reference , as well as the ports for the PC, the network and service .
The grille for the exhaust air is located, in the TP3M calibrators, in both the side walls of
the housing. In the TP37 calibrators, the grille is located in the upper plate of the housing
in the range of the opening of the metal block.
The rear part of the housing holds a heat-insulated calibration block with heating or cooling
elements and an integrated sensor for the reference temperature. In the case of the dry
block and multifunction calibrator, this is a metal block and in the micro bath calibrator, it
is a tank .
In the base, there are grilles for cooling the calibrator. The built-in fans control the inlet air
of the housing and of the calibration block .

3.2 Function
IMPORTANT NOTICE!
For your safety, manual operation of the calibrator, i.e. directly starting it up and its re-
maining at a certain temperature, is not possible.
The testing procedure is always started with a testing task (§ 3.3).
This ensures that the calibrator is always started with a defined "Behavior at test end"
(p. 24).
The calibrators can be used with dry block, infrared, surface or micro bath function.
The function is determined by the calibrator type and the used measuring insert.

Method of working:
Adapter sleeves or calibration inserts that are suitable for the temperature sensors or tem-
perature measuring instruments to be tested are inserted in the calibrator (§ 4.3
"Preparing of the calibrator").
They give the test specimen a secure fit and ensure optimum heat transfer.
Once all the preparations have been carried out, the calibrator can be switched on (§ 4.4).
The calibrator heats or cools the metal block or tank to the set temperature. As soon as this
temperature has been reached and is stable, the calibrator signals accordingly.
The calibration of the test specimen can now be carried out. Then, the next test point is ap-
proached or the testing procedure is ended.
Functionality:
The measuring inserts (p. 16) of the calibrator have different characteristic values, which
were determined in our laboratory through calibration. These characteristic values are de-
fined at the factory and stored in the calibrator as a protected function.
To be able to use a measuring insert, the relevant "Functionality of the calibrator" (§ 5.4)
must be selected.
IMPORTANT! Protected list entries!
The functions, test specimens and test tasks marked with the symbol are factory-
defined. They can be neither deleted nor configured.
They serve as templates for your own functions, test specimens and test tasks, which are
marked with the symbol.

TP37 / TP3M Construction, Function and Test Task
Technical changes reserved - 13 -
3.3 Test tasks
Test tasks are containers for defined test conditions. They are helpful for recurring testing
processes, for standardising test sequences and for generating measurement logs.
All the required settings and configurations for the calibration of a test specimen are com-
piled in a test task. The parameters of the testing task are saved and linked to the selected
function and test specimen (§ 5.6).
The operation concept of the calibrator is based on pre-installed and self-defined test tasks.
They are a central component of the function and operation of the TP37 / TP3M.
The emphasis of the operating manual is on the use of test tasks during operation of the cali-
brator.
The calibrator is shipped with functions, test samples and testing tasks defined in the factory,
in which the basic settings of the calibrator are stored. If desired, customer-specific test
tasks can also be pre-set.
These protected test tasks can be neither deleted nor edited. They serve as templates for
your own self-defined test tasks. They can be copied and can then be configured.
You can define your own test tasks for different test specimens or test sequences. These test
tasks are directly saved in the calibrator and can then be easily activated. This makes quick
access to recurring test tasks possible.
Upon switching on the calibrator, the first test task of the selection list is loaded automatical-
ly, with the relevant parameters.
IMPORTANT! The function and test specimen are independent!
During the configuration of test tasks (§ 5.6) when selecting the function or the test
sample, you can switch to the respective expert mode for administration and configura-
tion.
Note here that changes to existing functions and test specimens always apply to all
the test tasks linked to them.

The function of the calibrator is determined by the measuring insert. The required measuring
insert is inserted in the opening of the metal block or the tank.
It is thus easily possible to switch between the dry block, infrared, surface and micro bath
functions.
Each measuring insert has its own characteristic values, which are defined at the factory.
These characteristic values are influenced by different factors, such as: Diameter, type and
material of the measuring insert, number and diameter of the bore holes or the physical
properties of the calibration liquid.
These characteristic values are stored as protected functions for the accompanying measur-
ing inserts of the calibrator (§ 5.4).

Adapter sleeves with single or multiple holes are used for the calibration of straight temper-
ature sensors.
To achieve the specified accuracy of the calibrators (§ 10.1) the temperature
sensor (test specimen) and the adapter sleeve must be matched to one another:
•The borehole of the adapter sleeve may be a maximum of 0.5 mm larger than
the diameter of the test specimen.
•The measurement element of the test specimen must be located in the ho-
mogeneous temperature zone of the adapter sleeve.
Please also follow the "Details of the DKD technical committee "Temperature
and Humidity" for the operation of temperature block calibrators" (§ 11).
Inserting:
The appropriate adapter sleeve is inserted
into the metal block with the aid of the
sleeve exchange tool.
Center the adapter sleeve so that there is
an even air gap between the adapter sleeve
and the block.
External reference sensor (optional):
Align the adapter sleeve so that the hole
for the external reference sensor is locat-
ed at 12 o’clock.
Removing and cleaning:
Let the calibrator cool before you remove the adapter sleeve.
Pull the adapter sleeve out of the metal block with the help of the sleeve exchange tool.
Clean the adapter sleeve and the metal block.
This prevents the adapter sleeve from getting stuck in the metal block.

A special infrared insert is used for the contact-less measurement infrared thermometers.
This makes calibration fast and easy.
The infrared insert has a special design and surface coating on the in-
side. As a result, an emissivity of 0.9994 (black body) is reached.
The additional holes in the border (2 x 3.5 mm • 1 x 4.5 mm) are for ex-
ternal reference sensors. In this manner, the exact temperature on the
inside of the infrared insert can be measured.
IMPORTANT! Size of the measuring spot!
The measuring spot of the infrared thermometer must project itself to the floor of the in-
frared insert during the calibration. The measuring spot must be smaller than the inner
diameter and must not touch the wall of the infrared insert.
Inserting:
The infrared insert is inserted into the metal block with
the aid of the sleeve exchange tool.
Center the infrared insert so that there is an even air
gap between the infrared insert and the block.
External reference sensor (optional):
Align the infrared insert so that the hole for the external
reference sensor is located at 12 o’clock.
Removing and cleaning:
Let the calibrator cool before you remove the infrared
insert.
Pull the infrared insert out of the metal block with the help of the sleeve exchange tool.
Clean the infrared insert and the metal block.
This prevents the infrared insert from getting stuck in the metal block.
FORMATION OF ICE AND DEW!
At temperatures < 0 °C and higher humidity levels ice or condensation can form in the in-
frared insert. This can result in the calibration of the infrared thermometer being dis-
torted.
The forming of ice or condensation can be significantly reduced by covering the measuring
opening of the infrared insert.
Keep the measuring opening closed for as long as possible.
Only open the measuring opening briefly for measuring.
Existing ice or condensation can be removed by heating the infrared insert.

A special surface insert is used for calibrating surface temperature sensors. This makes cal-
ibration fast and easy.
The surface insert is hollow from the bottom and longer
than the adapter sleeve. For reference sensors, three bore-
holes are located directly under the surface (1 x 3mm •
1x 3,1mm • 1x 4,5mm). Thus, the exact surface tempera-
ture of the insert can be measured.
The two threaded boreholes in the border are for the ac-
companying exchange tool.
Inserting:
The surface insert is inserted into the metal block with
the aid of the exchange tool.
Center the surface insert so that there is an even air
gap between the surface insert and the block.
External reference sensor (optional):
Align the surface insert so that the hole for the external
reference sensor is located at 12 o’clock.
Removing and cleaning:
Let the calibrator cool before you remove the surface insert.
Pull the surface insert out of the metal block with the help of the exchange tool.
Clean the surface insert and the metal block.
This prevents the surface insert from getting stuck in the metal block.
IMPORTANT NOTICE!
The calibration of surface temperature sensors is very difficult and not uncontroversial.
The temperature sensor, which are placed on the surface, conduct heat away from the
surface and thus produce a cold spot on the surface to be measured.
Using a multifunction calibrator, the calibration temperature is generated in a specially con-
structed surface insert and measured directly under the surface with an external reference
thermometer.
The reference thermometer also determines the temperature of the cold spots by integrating
the temperature over the sensitive length of the reference thermometer and can therefore
offer a true temperature calibration of surface temperature test specimens.
The surface insert is constructed in such a way that the included external reference delivers
the best possible results because the depth of the boreholes is adapted to the sensitive
length. If you need to make your own external reference for a comparison calibration, ensure
that the sensitive length is known and that it is situated in the middle of the calibration sur-
face

CAUTION! Risk of injury - Wear safety goggles!
Calibration liquid can be ejected when working with the micro bath calibrator.
Always wear safety goggles for the eyes when handling calibration liquids.
The micro bath is used for calibrating sensors with special shapes or dimensions. Direct con-
tact between the sensor and the calibration liquid ensures excellent heat transfer.
The calibration liquid is poured directly into the tank or into a tub insert (p. 21).
The micro bath includes the transport cover, the work cover, the sensor cage, the magnetic
stirrer, the drain syringe, the magnetic lifter and as an accessory, the tub insert. The individ-
ual components are described below.
Transport cover:
The transport cover serves for secure closing of the micro bath. It prevents spillage of the
calibration liquid during transport.
CAUTION! Safety valve!
The transport cover is equipped with a safety valve, which is activated once
the pressure reaches ~1.5 bar. This can result in hot steam being released.
Always unscrew the transport cover before putting the micro bath into
service, in order to avoid excessive pressure.
Work cover:
The work cover fulfils various tasks during the operation.
•It reduces the evaporation of the calibration liquid to a minimum.
•It reduces the cooling on the surface of the calibration liquid.
•It ensures stable positioning of the test specimens in the micro bath.
The work cover is screwed on to the micro bath and has five openings for
test specimens. The unused openings can be closed with suitable silicon
plugs.
Sensor cage and magnetic stirrer:
The sensor cage protects the magnetic stirrer. It prevents the sensors from
blocking the magnetic stirrer. The function of stirring is ensured by the sen-
sor cage.
The magnetic stirrer ensures a uniform temperature distribution in the cal-
ibration liquid. The speed of the magnetic stirrer is set in Configuration
range (§ 5.2) or in the window "Configure Function" (§ 5.4.3 "Stirring
speed").
IMPORTANT! Limited life part!
The magnetic stirrer is a limited life part.
Replace worn-out magnetic stirrers. (§ 8.1 "Maintenance").
