ETC-calibrators are temperature calibrators designed to calibrate temperature sensors. Read this manual carefully before using the instrument and make sure that all safety instructions and warnings are observed.

Read this manual carefully before using the instrument! In order to avoid any personal injuries and/or damage to the instrument all safety instructions and warnings must be observed. These calibrators contain Electrical and Electronic circuits and must be recycled or disposed of properly (in accordance with the WEEE Directive 2012/19/EU). • 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...

• 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...

• Do not touch the well, the insertion tube or the grid plate, as the calibrator is heating up / has been heated 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. 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. A Caution - Cold surface Below 0°C/32°F (applies...

• 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 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. • The insertion tube must always be...

Warning • 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...

• Never use heat transfer fluids such as silicone, oil, paste, etc. in the calibrators. These fluids may penetrate the calibrator and cause electrical hazard, damage or create poisonous fumes. • 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 handle of the calibrator during use - it may be very hot and cause burns.

Follow the instructions below before using the calibrator (cf. Fig. 1): Place the calibrator on an even horizontal surface away from all draughts. Do not use the instrument if the fan is out of order. Ensure a free supply of air to the fan (pos. 5). 2. Check that the voltage shown on the label above the power control switch is identical to the mains voltage (ETC-400 only). If not, the instrument should be returned to AMETEK Denmark A/S or the distributor for replacement. 3. Plug in the cable below (pos. 3) the power control switch (pos. 4) and check that the earth connection is present. 4. The...
