Scratches and other damage to the insertion tubes
should be avoided by storing the insertion tubes
carefully when not in use.
4.1 Switching off the calibrator
The following routine must be observed before the insertion tube is
removed and the instrument turned off (cf. Fig. 1) :
1.
If the calibrator has been heated up to temperatures above
50°C/122°F, you must wait until the instrument reaches a
temperature below 50°C/122°F before you switch it off.
2. If the calibrator has reached a temperature below 0°C/32°F,
it should be heated momentarily to a temperature of
100°C/212°F.
3. Turn off the calibrator using the power control switch (pos.
4).
4. Remove the insertion tube from the calibrator using the tool
supplied with the instrument.
