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. The screen menus shown in this manual represent the menus displayed when using a B-version. Disposal - WEEE Directive These calibrators contain Electrical and Electronic circuits and must be recycled or disposed of properly (in accordance with the WEEE Directive 2012/19/EU). • Always supply the calibrator using a power circuit which is separate from essential safety equipment and vital hospital equipment etc., to...

• The PTC-125 contains R-1270 and R-704 under pressure. The calibrator must under no circumstances be stored at ambient temperatures above 50°C (122°F) or operated at ambient temperatures above 40°C (104°F). Doing so may cause a hazard. • 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: • For B and C versions only, the sockets on the input module must NEVER be connected to voltages exceeding 30V with reference to ground. • Thermostats must not be connected...

• If the calibrator has reached a température below 0°C/32°F, ice crystals may form on the insertion tube and on 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 min. 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. • Do not use the instrument if the internal fan is out of order. •...

• 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...

When setting up the dry-block calibrator, you must… Place the calibrator on an even horizontal surface where you intend to use it. Caution… Do not use the instrument if the internal fan is out of order. 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). To check; do as follows (see fig. 1): Warning The two main fuses must...

Choice of 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 calibration in the PTC-350/660 instruments, the insertion tubes must be heated up to maximum temperature 350°C (662°F) / 425°C (797°F) / 660°C (1220°F) for a period of minimum 30 minutes (PTC-350/425/660...
