Setting the main voltage and replacing the fuses

Warning

• The fuse box must not be removed from the power control switch until the mains cable has been disconnected.
• The two main fuses must have the specified current and voltage rating and be of the specified type. The use of makeshift fuses and the short-circuiting of fuse holders are prohibited and may cause a hazard.

1. Locate the main fuses in the fuse box in the power control switch and 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.
2. Open the lid of the fuse box using a screwdriver.
3. Remove the fuse box.
4. Remove both fuses and insert two new fuses. These must be identical and should correspond to the line voltage.

• ITC-155: 115V, 2AT = 105014 / 230V, 1AT = 105007
• ITC-320/650: 115V, 10AF = 60B302 / 230V, 5AF = 60B301

If the fuses blow immediately after you have replaced them, the calibrator should be returned to the manufacturer for service.
Slide the fuse box into place with the correct voltage turning upwards.

After use

Warning
Never leave hot insertion tubes which have been removed from the calibrator unsupervised – they may constitute a fire hazard or personal injury.
If you intend to store the calibrator in the optional carrying case after use, you must ensure that the instrument has cooled to a temperature below 100°C/212°F before placing it in the carrying case.

Caution…

• The insertion tube must always be removed from the calibrator after use.
• The humidity in the air may cause corrosion oxidation on the insertion tube inside the instrument. There is a risk that the insertion tube may get stuck if this is allowed to happen.
• If the calibrator is to be transported, the insertion tube must be removed from the well to avoid damage to the instrument.
• Scratches and other damage to the insertion tubes should be avoided by storing the insertion tubes carefully when not in use.

Caution – Hot surface

• Do not touch the grid plate, the well or the insertion tube – they may be very hot and cause burns.
• Do not touch the tip of the sensor when it is removed from the insertion tube/well – it may be very hot and cause burns.
• Do not remove the insert from the calibrator before the insert has cooled down to less than 50°C/122°F.

Switching off the calibrator

The following routine must be observed before the insertion tube is removed and the instrument switched 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. Switch off the calibrator using the power control switch (pos. 5).
4. Remove the insertion tube from the calibrator using the tool supplied with the instrument.
5. Optional: Store the calibrator in the carrying case.
