Disposal – WEEE Directive
These calibrators contain Electrical and Electronic circuits and must be recycled or disposed of properly (in accordance with the WEEE Directive 2002/96/EC).
Warning
About the use:
The calibrator must not be used for any purposes other than those described in this manual, as it might cause a hazard.
The calibrator has been designed for indoor use only and is not to be used in wet locations.
The calibrator is not to be used in hazardous areas, where vapour or gas leaks, etc. may constitute a danger of explosion.
The calibrator is not designed for operation in altitudes above 2000 meters.
The calibrator is a CLASS I product and must be connected to a mains outlet with a protective earth connection. Ensure the ground connection of the calibrator is properly connected to the protective earth before switching on the calibrator. Always use a mains power cable with a mains plug that connects to the protective earth.
To ensure the connection to protective earth any extension cord used must also have a protective earth conductor.
Only use a mains power cord with a current rating as specified by the calibrator and which is approved for the voltage and plug configuration in your area.
Before switching on the calibrator make sure that it is set to the voltage of the mains electricity supply.
Always position the calibrator to enable easy and quick disconnection of the power source (mains inlet socket).
The calibrator must be kept clear within an area of 20 cm on all sides and 1 metre above the calibrator due to fire hazard.
Never use heat transfer fluids such as silicone, oil, paste, etc. in the dry-block calibrators. These fluids may penetrate the calibrator and cause electrical hazard, damage or create poisonous fumes.
The calibrator must be switched off before any attempt to service the instrument is made. There are no user serviceable parts inside the calibrator.
When cleaning the well or the insertion tube, REMEMBER to wear goggles when using compressed air!
About the frontpanel:
The connectors, on the front panel of the calibrator, must NEVER be connected to a voltage source.
Thermostats connected to the switch test input must not be connected to any other voltage source during a test.

About insertion tubes and insulation plugs:
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 aluminium carrying case after use, you must ensure that the instrument has cooled down to a temperature below 50°C/122°F before placing it in the carrying case.
Never place a hot insertion tube in the optional carrying case.
Use only insulation plugs supplied by AMETEK Denmark A/S.
About the fuses:
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.
Caution – Hot surface
This symbol is visible on the grid plate.
Do not touch the grid plate, the well or the insertion tube as the calibrator is heating up – 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 touch the handle of the calibrator during use – it may be very hot and cause burns.
Over 50°C/122°F
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.
Do not remove the insert from the calibrator before the insert has cooled down to less than 50°C/122°F.
Caution – Cold surface
Below 0°C/32°F (applies only to the CTC-155 C models)
Do not touch the well or insertion tube when these are below 0°C/32°F - they might create frostbite.
If the calibrator has reached a temperature below 0°C/32°F, ice crystals may form on the insertion tube and the well. This, in turn, may cause the material surfaces to oxidize
To prevent this from happening the insertion tube and the well must be dried. This is done by heating up the calibrator to 100°C/212°F until all water left has evaporated.
Remove the insulation plug while heating up.
It is very important that humidity in the well and insertion tube is removed to prevent corrosion and frost expansion damages.

Caution…
About the use:
Do not use the instrument if the internal fan is out of order.
Before cleaning the calibrator, you must switch it off, allow it to cool down and remove all cables.
About the well, insertion tube and grid plate:
The well and the insertion tube must be clean and dry before use.
Do not pour any form of liquids into the well. It might damage the well or cause a hazard.
Scratches and other damage to the insertion tubes should be avoided by storing the insertion tubes carefully when not in use.
The insertion tube must never be forced into the well. The well could be damaged as a result, and the insertion tube may get stuck.
Before using new insertion tubes for the calibration, the insertion tubes must be heated up to maximum temperature 350°C(662°F) / 660°C (1220°F) for a period of minimum 30 minutes (CTC-350/660 only).
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.
Note…
The product liability only applies if the instrument is subject to a manufacturing defect. This liability becomes void if the user fails to follow the instructions set out in this manual or uses unauthorised spare parts.

Check that the insulation plug fits the diameter of the sensor. Otherwise replace it (CTC-155 only).
In order to spare the sensor and its connections it is recommended to use a thermal protection shield (129264) at high temperatures (CTC-350/660 only).
Caution…
The well and the insertion tube must be clean before use.
Do not pour any form of liquids in the well. It might damage the well.
Scratches and other damage to the insertion tubes should be avoided by storing the insertion tubes carefully when not in use.
The insertion tube must never be forced into the well. The well could be damaged as a result, and the insertion tube may get stuck.
Caution – Hot surface
Do not touch the grid plate, the well or the insertion tube as the calibrator is heating up – 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 touch the handle of the calibrator during use – it may be very hot and cause burns.
Do not remove the insertion tube from the calibrator before the insertion tube has cooled down to less than 50°C/122°F.
Caution – Cold surface
Below 0°C/32°F (applies only to the CTC-155 models)
Do not touch the well or insertion tube when these are below 0°C/32°F - they might create frostbite.
If the calibrator has reached a temperature below 0°C/32°F, ice crystals may form on the insertion tube and the well. This, in turn, may cause the material surfaces to oxidize
