Follow the instructions below before using the calibrator (cf. Fig. 1):
1.
Place the calibrator on an even horizontal surface away from
all draughts.
Caution…
Do not use the instrument if the ventilator is out of order.
Ensure a free supply of air to the ventilator located at the
bottom of the instrument (pos. 9).
2.
Check that the voltage shown on the power control switch
(pos. 7) is identical to the mains voltage.
3. Plug in the cable below the power control switch (pos. 8) and
check that the earth connection is present.
4. Select an insertion tube (pos. 4) with a well diameter that
matches the sensor (pos. 1) to be calibrated. Insert the
insertion tube in the well of the calibrator (note that the well
and the insertion tube
must be clean before use).
5. If the design of the sensor permits it, use an insulation tube
(pos. 2) and insulation (pos. 3) for the best results. These
should be mounted as shown in Fig. 1.
6. Place the sensor (pos. 1) in the insertion tube (pos. 4) as
shown in Fig. 1.
7. In order to spare the sensor and its connections it is
recommended to use a heat protection shield (104216) at
high temperatures.
