CTC-calibrators are temperature calibrators designed to calibrate temperature sensors and temperature switches. Read this manual carefully before using the instrument and make sure that all safety instructions and warnings are observed. When you receive the instrument, the following should be enclosed: • 1 USB memory stick containing electronic Reference manual and software package JOFRACAL • 1 set of test cables (1 black, 1 red) • 1 thermal protection shield (CTC-652/660 only) • 1 tool for insertion tube • 1 Calibration certificate (International traceable)

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. Disposal - WEEE Directive /V®\ 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 has been designed for indoor use...

• 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 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. About the front panel: • 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...

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. • Before cleaning the calibrator, you must switch it...

Ambient operating temperature range: 0-50°C / 32-122°F Storage temperature range: -20-50°C / -4-122°F Humidity range: 5-90% RH, non-condensing Electromagnetic Compatibility: Tested for use in domestic establishment and in establishments directly connected to low voltage power supply network which supplies buildings used for domestic purposes as well as in an industrial electromagnetic environment as described in EN61326-1:2013. IEC protection class: Power consumption: 3.1 Before use Warning • The calibrator must not be used for any purposes other than those described in this manual, as it might...

• Always make sure to position the power cord and other connected cables in a secure way to prevent the risk of personnel falling. • To prevent the calibrator from tipping over and causing damage to equipment or systems, please avoid pulling the cables connected to the calibrator. • 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 connectors, on the front panel of the calibrator, must NEVER be connected to a voltage...

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. 4. Check that the earth connection for the instrument is present and attach the cable. Place the sensor (pos. 3) in the insertion tube (pos. 4) as shown in the figure below. 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)...
