3.2 Function

IMPORTANT NOTICE!
For your safety, manual operation of the calibrator, i.e. directly starting it up and its remaining 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. 25).
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.
Dry block Infrared Surface Micro bath
Method of working:
Adapter sleeves or calibration inserts that are suitable for the temperature sensors or temperature 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 approached or the testing procedure is ended.
Functionality:
The measuring inserts ( p. 17) of the calibrator have different characteristic values, which were determined in our laboratory through calibration. These characteristic values are defined 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 factory­defined. 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.
Construction, Function and Test Task Series TCL-3M165E2

3.3 Test tasks

Test tasks are containers for defined test conditions. They are helpful for recurring testing processes, for standardizing test sequences and for generating measurement logs.
All the required settings and configurations for the calibration of a test specimen are compiled 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 TCL-3M165E2.
The emphasis of the operating manual is on the use of test tasks during operation of the calibrator.
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 automatically, 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 configuration.
Note here that changes to existing functions and test specimens always apply to all
the test tasks linked to them.

4 Commissioning and operation

CAUTION! Risk of injury or material damage!
The calibrator can become very hot during operation. If the calibrator is operated without supervision, third-party persons in the vicinity could get injured. Moreover, flammable material could get into the calibrator and cause significant damage to property.
Never leave the calibrator unattended when it is in operation or in the cooling phase.
For safe operation of the calibrators of the TCL-3M165E2 series, a proper commissioning procedure is necessary.
Commissioning includes the installation, the electrical connections, the preparation for the test task as well as correct switching on and off of the calibrator. Further, a visual inspection for damage is required before use.
The required steps are described in the following sections.
IMPORTANT! Please also follow the instructions for intended use ( § 1.2), the safety instructions ( § 2) and the information on the ambient conditions ( p. 56).

4.1 Operating conditions

Select a safe installation site for commissioning the calibrator.
Installation site and operating position:
Only suitable for indoor use, do not use outdoors. Operate only in the vertical position on an even surface. The surface must be stable,
clean, and dry. If the operation positions do not conform to the above, the structural safety and the specified properties of the calibrator are not guaranteed.
At higher testing temperatures, please use a sufficiently big, fire-resistant supporting
surface.
Sufficient clearance around the calibrator
On the front side > 1 m, behind and to the sides > 0.5 m. Head clearance and sufficient clear space above the calibrator.
Sufficient ventilation must be ensured. Do not operate in the vicinity of flammable materials. Do not install in a cupboard or other similar location. The ventilation openings must not be blocked or covered. The calibrator must be installed so that it can be switched off at any time.
IMPORTANT! "KILL" switch! The plug of the power connecting cable serves as a "KILL" switch.
Ensure that the plug is always easily accessible and easy to reach. In an emergency, pull the plug, so that the calibrator is isolated from the power.
Commissioning and operation Series TCL-3M165E2

4.2 Electrical connection

The electrical connections are made with the supplied power connecting cable.
DANGER! Risk of death due to electric current!
The TCL-3M165E2 is operated at power voltages up to 240 VAC. Contact with the power voltage can result in serious or fatal injuries.
Switch off the TCL-3M165E2 and remove the power connecting cable before you start
any work on live parts.
Check the following points before you connect the calibrator: Operate the calibrator only with the approved supply voltage ( § 10.1). Ensure that the
power voltage is the same as that specified on the type plate.
Please follow the local regulations of the energy supplier. Connect the calibrator only to a properly installed and earthed 3-pole outlet. Do not use any extension cables or adapter plugs.
IMPORTANT! Power connecting cable! The power connecting cable may only be replaced by an equivalent cable.
Use only original cables from OMEGA ENGINEERING or approved cables of the
same type with the correct design as replacements ( "Electrical characteristics").
Connect TCL-3M165E2:

Series TCL-3M165E2 Commissioning and operation

4.3 Preparing of the calibrator

The preparations for the test task must be carried out with the calibrator switched off and cooled to ambient temperature.
CAUTION! Risk of burns!
The calibrator can become very hot when in operation. Touching hot parts can result in serious burn injuries.
Never touch the metal block, the tank, the adapter sleeve or the test specimen at
temperatures above 35 °C or below 10 °C (95 °F or below 50 °F).
Allow the calibrator to cool before you remove the test specimen, clean the tank,
change the adapter sleeve or the calibration insert or switch off the calibrator.
IMPORTANT! Empty the tank and clean it! The tank must be emptied and cleaned to prevent the adapter sleeve or the calibration
insert from getting stuck. Empty and clean the tank before you insert another adapter sleeve or calibration
insert.
Measuring insert:
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 measuring inserts of the calibrator ( § 5.4).
