1) Unpack and check the calibrator and the accessories carefully. 2) Check the parts according to the list shown below. If any of the parts are missing or damaged, please contact the dealer who sold you the calibrator. • 1 USB memory stick containing electronic Reference manual and software package JOfRaCAL • 1 sets of test leads and test clips (black and red) • Thermal protection shield (CTC-652/660 only) • 1 tool for insertion tube • 1 Calibration certificate (International traceable) When reordering, please specify the part numbers according to the list of accessories, section 11.0

Read this manual carefully before using the instrument! Please follow the instructions and procedures described in this manual. They are designed to allow you to get the most out of your calibrator and avoid any personal injuries and/or damage to the instrument. 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 protection provided by the calibrator may be impaired and it might cause a hazard....

• 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! • Remember to use appropriate protective equipment or get help when carrying the calibrator (for a longer distance) in order to prevent injuries from dropping the calibrator. • 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...

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...

• 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 / 3000 meters (CTC-1205). • 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...

Ensure a free supply of air to the internal fan located at the bottom of the instrument (pos. 2). The area around the calibrator should be free of draught, dirt, flammable substances etc. Check that the fuse size corresponds to the applied voltage on (pos. 3). The fuse is contained in the power control switch (on/off switch (230V/115V)). To check; do as follows (see Fig. 1): Warning 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. A. Open...

Choosing an insertion tube Caution… To get the best results out of your calibrator, the insertion tube dimensions, tolerance and material are critical. We highly advise using the JOFRA insertion tubes, as they guarantee trouble free operation. Use of other insertion tubes may reduce performance of the calibrator and cause the insertion tube to get stuck. Caution… Before using new insertion tubes for the calibration in the CTC-350/652/660/1205 instruments the insertion tubes must be heated up to maximum temperature 350°C(662°F) / 650°C (1202°F) / 660°C (1220°F) / 1205°C (2201°F) for a period of...
