• 1 set of silicone plugs for insulation plugs (RTC-156/157/158/159/187/250 and PTC-125/155 only) • 1 insulation collar (RTC-156 only) • 1 protection shield (RTC-700 and PTC-660 only) Caution Do not use the RTC-158 insulation plug (black POM) with the RTC-250 instrument due to the risk of melting. Always use the correct - yellow/brown PEEK - insulation plug with the RTC-250 instrument. RTC-158/250 A/B/C only (liquid bath) - OPTIONAL • 1 liquid bath kit consisting of : - 2 lids for transportation / calibration - 1 stirring magnet remover - 1 liquid drainage syringe - 1 oil material safety data...

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. 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...

• 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 free within an area of 20 cm on all sides and 1 metre above the calibrator...

• The RTC-159 and PTC-125 contains R-1270 and R-704 under pressure. The calibrator must under no conditions 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. 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 to any other voltage sources during test. About insertion tubes, insulation plugs, well and • Never leave hot insertion tubes which have been removed from the...

• Do not pour cold fluid into a hot well - it might cause an explosion. • AMETEK Denmark A/S does not take any responsibility, if the well is filled with other fluids than those recommended. • Liquid baths should only be operated by trained personal. • Heat transfer fluids must only be used in calibrators prepared as a liquid bath. If these fluids are heated above specified temperature they will create noxious or toxic fumes. Proper ventilation must be used. • To avoid hazards from treating fluids in a wrong manner, always reduce the "Max. SET-temperature allowed” in the CALIBRATOR SETUP MENU...

Caution - Hot surface This symbol is engraved in the grid plate. • Do not touch the grid plate, the well or the insertion tube when the calibrator is heating up - they may be very hot and cause burns. • Do not touch the lid or the spill tray when the calibrator is heating up - they may be very hot and cause burns (RTC-158/250 A/B/C only). • 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. If the calibrator has been heated up to temperatures...

• 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. • Before cleaning the calibrator, you must switch it off, allow it to cool down and remove all cables. About the liquid bath (RTC-158/250 A/B/C only): • Be careful not to overfill the well with oil. • Avoid getting silicone oil on the clothes. It is impossible to wash off. • The oil level rises several centimetres when the temperature is rising. Please read instructions in section 3.1.2 about oil level....
