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.
Check the voltage of the power control switch (on/off switch
(230V/115V)). If the voltage of the power control switch
differs from the line voltage, you must adjust the voltage of
the power control switch as follows (see Fig. 1):
A. Open the fuse box lid using a screwdriver.
B. Take out the fuse box.
C. Remove both fuses and insertion tube two new fuses.
These must be identical and should correspond to the
line voltage. See section 10.0.
B. Turn the fuse box 180° and slide it into place.
Check that the earth connection for the instrument is present
and attach the cable.
g
Select an insertion tube with the correct bore diameter. See
section 3.3 for information on how to select insertion tubes.
The calibrator is now ready for use.
3.3 Choice of insertion tube
Caution…
Before using new insertion tubes for the calibration, the
insertion tubes must be heated up to maximum temperature
- 320°C (608°F) / 650°C (1202°F) - for a period of minimum
30 minutes.
In order to ensure the best calibration of your sensors
please avoid using insertion tubes in the ITC-320 calibrator
which have been used in the ITC-650 calibrator.
