5. Repeat step 3 for all the required calibration set points.
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 required settings and configurations for the calibration of a DUT are compiled in a test task.
The parameters of the testing task are saved and linked to the selected function and DUT. See
Section 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 calibrator.
The emphasis of the operating manual is on the use of test tasks during operation of the
calibrator.
The calibrator is shipped with pre-defined functions, test samples and testing tasks. These have
been defined in the factory, in which the basic settings of the calibrator have been stored.
The protected test tasks can be neither be deleted nor edited. They serve as templates for your
own self-defined test tasks. They can be copied and then modified. This task must not be
completed without specific training from Druck.
You can define your own test tasks for different DUT or test sequences. These test tasks are
directly saved in the calibrator and can 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.
4. Commissioning and Operation
For safe operation of the calibrators, a formal commissioning procedure is necessary.
Commissioning includes the installation, electrical connections, preparation for the calibration 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.
INFORMATION The function and the DUT are independent. During the
configuration of test tasks (Section 6), the respective expert mode can be
entered. This allows administration and configuration when selecting the
function or DUT.
Note that changes to existing functions and DUTs always affect all linked test
tasks.
WARNING The calibrator may 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 come into contact with
the calibrator and cause significant harm to personnel and/or damage to
property.
Never leave the calibrator unattended when it is in operation or in the cooling
down phase.

4.1 Operating Conditions
Select a safe installation site for commissioning the calibrator.
Considerations for selecting a safe installation site and calibrator 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 operational conditions do not conform to the above, the structural safety and the
specified properties of the calibrator cannot be guaranteed.
• At high testing temperatures, it is recommended to use a sufficiently large, fire-resistant,
supporting surface.
• Ensure sufficient clearance around the calibrator. On the front side > 1m, behind and to the
sides > 0.5 m. Ensure that there is sufficient head clearance and sufficient clear space above
the calibrator.
• Ensure sufficient ventilation.
• Do not operate in the vicinity of flammable materials.
• Do not install in a cupboard or other similar confining 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.
4.2 Electrical Connection
Check the following points before you connect the calibrator:
1. Check the specified operating mains supply voltage range for the calibrator. See Section 13.
2. Ensure that the mains voltage range is the same as that specified on the rating plate.
3. Only connect the calibrator to a properly installed and earthed 3-pole socket for mains plugs
with earthing contact.
4. Only use extension cables or adaptor plugs with a protective earth connection.
4.2.1 Electrical Connection Procedure
1. Insert the mains cable into the mains inlet socket of the calibrator.
2. Insert the plug of the mains cable in a suitable mains outlet with earthing contact.
INFORMATION The plug of the mains connecting cable serves as a
emergency stop device. 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 mains.
RISK OF ELECTRIC SHOCK Calibrators that have been exposed to high
humidity for long periods have an initial higher than normal earth leakage
current. Ensure that the calibrator is always connected to a protective earth.
Always use a known good mains cable with an appropriate power plug.
Use only a Druck specified mains cable.
Ensure that the mains outlet is adequately rated and has a protective earth
connection.
Before turning on the power, make sure that the calibrator is properly connected
to the protective earth. The protective earth is connected to the calibrator
through the mains plug.
