5 Commissioning of the calibrator
5.1 Intended use
The introduction of foreign substances such as oil or thermal conduction paste with the aim of
enhancing the heat transfer to the probe can damage the calibrator and the adaptor insert.
In addition, there is a risk of injury due to abruptly evaporating fluids and hazardous gases that may
form when fluids evaporate.
Always ensure that the testing temperature is not too high for the probe. Otherwise, the probe may be
destroyed.
Remove all highly combustible media from the vicinity of the calibrator and ensure that the calibrator
cannot come into contact with easily inflammable or explosive media.
5.2 Checks and activities prior to commissioning
Prior to commissioning, the calibrators must be moved to their standard upright operating position. When
installing the calibrator, make sure that the fan on the bottom can circulate a sufficient rate of air. Do not use
soft, resilient surfaces.
Proceed as follows:
Check the technical data specified on the type label
Always place TP 38… / TP 38… E in an upright position. Otherwise uniform temperature distribution in
the block cannot be ensured.
Do not use any filling media.
Additionally observe the following:
The calibrator must be connected to a power circuit with minimum risk of a power failure, since it will no
longer be possible to supply cooling air in the case of a power failure
All the bores of the adaptor insert must be clean and free of damage and foreign matters
The probe, the adaptor insert and the bore of the heating block must exactly match.
Keep the heat transition resistance as low as possible by using adaptor inserts with test bores, the
inside diameters of which is approx. 0.5 mm larger than the diameter of the probe.
Setup and connection
First fold back the hand grips of the calibrator. For this purpose, pull off the two lateral fasteners of the
hand grip to the side and fold the hand grip back towards the rear of the calibrator.
Plug the power cable supplied into the mains socket on the bottom of the calibrator and plug the power
connector into the mains socket.
Caution:
Since the housing of the calibrator is made of metal, only power cables with ground wire may be
used. Use the power cable supplied.
Set up the calibrator such that the power switch (switch for power supply) is easily accessible and can be
actuated without any problems.
Set up the calibrator such that the fan on the bottom of the calibrator has sufficient free space to be able to
circulate a sufficient cooling air rate. Insufficient venting may cause damage leading to the destruction of the
«TITLE»calibrator.
Connect the calibrator to a power circuit with minimum risk of a power failure, since it will no longer be
possible to supply cooling air in the case of a power failure
Switch on the calibrator at the power switch.
