Optional parts can also be found in the list of accessories.

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-model. /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...

• 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. • Remember to use appropriate protective equipment or get help when carrying the calibrator (for a longer distance) to prevent injuries from dropping the calibrator. About the front panel: • For B and C models only, the sockets on the input module must NEVER be connected to...

By reducing the "Max. SET-temperature allowed”, the calibrator cannot be used outside this temperature range. Be aware of the flash point, the boiling point and other liquid properties applicable to the usage when setting the Max. SET-temperature. Read the MSDS (Material Safety Data Sheet) of the liquid before use. The Max. SET-temperature must never exceed liquid flash point -40°C. • Always remove the liquid from the calibrator before transportation. • Product information on the liquid must be carefully investigated before use. • Do not pour water or any other liquids into a bath filled with...

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 cables and cables for attached accessories, such as sensors, in a safe way to reduce the risk of tripping. • When transporting (carrying) the calibrator, be extra careful not to drop it on other materials, equipment, and body parts. • Ensure...

• 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. • The insertion tube must always be removed from the calibrator after use. The humidity in the air may cause corrosion oxidation on the insertion tube inside the instrument. There is a risk that the insertion tube may get stuck if this is allowed to happen. • If the calibrator is to be transported, the insertion tube must be removed from the well to avoid damage to the instrument. • The tip of the sensor should rest at the bottom of the sensor basket for optimum...
