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. The screen menus shown in this manual represent the menus displayed when using a B-version. /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). • Always supply the calibrator using a power circuit which is separate from essential...

• Never use heat transfer fluids such as silicone, oil, paste, etc. in the dry-block calibrators. These fluids may penetrate the calibrator and cause electrical hazard, damage or create poisonous fumes. • 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 in the dry-block calibrator and cleaning oil in the liquid bath calibrator. • Use protection shield when calibrating at high temperatures (RTC-700)...

• 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 according to the specifications of the fluid to be used. If using a calibrator outside of the fluids specifications there is a risk of fire hazards, personal Injury or chemical release. By reducing...

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. • Before cleaning the calibrator, you must switch it off, allow it to cool down and remove all cables. • Always place power cable and cables to attached accessories, such as sensors, in...

• 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. • Before using new insertion tubes for the calibration, the insertion tubes must be heated up to maximum temperature - 250°C (482°F) / 700°C (1292°F) - for a period of minimum 30 minutes (RTC-250/700 A/B/C only). • The insertion tube must always be removed from the calibrator after use. The humidity in the air may cause corrosion oxidation...
