7. Maintenance 7.1. Replacing the thermistor Proceed as follows to replace the thermistor: Remove the blue measuring head cover. Undo the Phillips screw on the rear side of • the measuring head for this. The cover can be lifted off afterwards. There is a hole on each side of the bottom part of the measuring head. -
Page 18: Weee Notice
8. WEEE Notice The WEEE (Waste Electrical and Electronic Equipment) Directive, which was adopted by European legislation on February 13, 2003, has led to a major reconsideration of the disposal of electrical and electronic equipment. The purpose of this directive is primarily to avoid WEEE, i.e. electrical and electronic waste, and also to promote the reuse, recycling and other forms of continuing use of this type of waste in order to reduce waste quantities. -

Error codes Error code Description error lift: end position not reached, please check uncalibrated or defective thermistor error on calibration: please check solution frozen too early plateau not found not frozen cooling system not ready yet communication error error lift: end position not reached, please check When starting a measurement or calibration, the device tries to move the lift at... -
Page 20: D)Frozen Too Early
frozen too early The state of the sample is unstable when it is below its freezing point. It can therefore happen that the sample freezes due to an unintentional influence or on its own before the device triggers freezing. There are many possible reasons for this. If stirring is too strong or if the stirring rod is grinding against something, jolting can occur and trigger freezing. -
Page 21: H)Communication Error
communication error The connection to the measurement board is broken. This could caused by a defective cable or a defective measurement board. Both should be checked. 9.2. Detection of errors during use Most of the errors made during use of freezing point determination equipment are miscalibrations. -
Page 22: C)Defective Thermistor
Defective thermistor This is the most frequently occurring error. There are two possible causes: 1. The thermistor is (has been) broken off: This can be recognised by the display constantly, without any change, showing a negative value. 2. The glass shell of the thermistor is showing hairline cracks and is leaky: This manifests itself with extremely unstable measuring behaviour. -

Page 24: Appendix
Appendix 12.1. Principle of the freezing point determination The freezing point is the temperature at which the solid phase and the liquid phase of a substance or mixture of substances are present simultaneously and are in equilibrium. The best suitable method for determining the freezing point has proved to be cooling down the sample and then triggering the freezing. -
Page 25: A)Fixed Time
Fixed time Here, there is a fixed waiting time (freely configurable from 20 to 200 seconds) after triggering the freezing. After this time, the measured value has set itself to a certain temperature which is then output as the freezing point value. Advantage: relatively high sample throughput Drawback: low repeatability for strongly fluctuating fat contents. - Page 26 EC Machines Directive in its design and construction and in the configuration put on the market by us. This declaration is invalid if the machine is modified without our agreement. Machine description: CryoStar I Machine type: Gefrierpunktbestimmungsgerät Machine No.
