4.1 Setup and Connection
4. Operating the Calibrator
Connect the power cable supplied to the calibrator and plug the
power connector into the mains socket. Set up the calibrator such
that the fan on the bottom of the device 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 calibrator.
Set up the calibrator such that the power switch (switch for power
supply) is easily accessible and can be actuated without any
problems.
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.
Caution!
Ensure that all the bores of the heating block are clean and free
of damage. Do not use any filling media.
Place the calibrator in an upright position for the calibration
procedure to ensure optimum temperature distribution and
transmission.
Additionally take the following into consideration:
„
the probe
„ the adapting sleeve and
„ the bore of the heating block
must exactly match.
Keep the thermal contact resistance as low as possible by using
adapting sleeves with test bores, the inside diameters of which are
approx. 0.2 mm to max. 0.5 mm larger than the diameter of the
probe.
