1 Safety Instructions安全提示
• When working, ware the personal guard to avoid the risk from: •
当使用时，请注意人身安全以避免以下危险：
- Splashing and evaporation of liquids - Release of toxic or combustible gases. - 液体的喷溅及蒸发
- 有毒气体及可燃气体的释放。
•
Set up the instrument in a spacious area on an stable, clean, non-slip, dry and fireproof surface, do not operate the instrument in explosive atmospheres, with hazardous substances or under water.
• #p#分页标题#e#
请把产品安装在开阔，稳定，干净，防滑，干燥并且防火的地方。不能在易燃易爆，危险物品及潮湿环境下使用。
• Gradually increase the speed, reduce the speed if: •
请慢慢的调节速度当：
- The stirring bar breakaway because of too high speed
- The instrument is not running smoothly, or container moves on the base plate. - 搅拌子因为速度过快而跳动或者不转动。 -
产品运行不流畅或者容器移动**板面边缘。
• Beware of hazards due to: •
当操作时注意危险：
- Flammable material or media with a low boiling temperature - Overfilling of media - Unsafe container
- 易燃材料或者低沸点材料 - 样品过满 - 不安全的容器
• Process pathogenic materials only in closed vessels. • 如果是致病材料，请将其置于密闭容器中。
• If the case of the stirrer bar is PTFE, plate note: • 当搅拌子是PTFE材质时，请注意：
Elemental fluorine, three fluoride and alkali metals will corrode the PTFE and Halogen alkenes make it expansion at room temperature Molten alkali, alkaline earth metals or their solution, as well as the power in second and third ethnic of the Periodic Table of elements will have chemical reaction with PTFE when temperature reaches 300 ~400 ℃
氟元素，三氯化物及碱金属会腐蚀PTFE材料。在室温条件下卤素和烯烃会使其膨胀膨胀 。 碱金属或其他元素周期表中第二及第三周期的元素会和PEFE材料发生化学反应，当温度达到300 ~400 ℃时。
Check the instrument and accessories before hand for damage each time you use them.
每次使用前，请检查产品及配件是否完好以防止造成伤害。
Do not use damaged components. Safe operation is only guaranteed with the accessories described in the “Accessories” chapter. Accessories must be securely attached to the device and cannot come off by themselves. Always disconnect the plug before fitting accessories.
不要用已损坏的配件。配件必须完好的连接到机器上并且不能自动脱落。在安装配件时请拔掉电源。
• Ensure that the external temperature sensor is inserted in the media to a depth of at least 20mm.
• 确保外部温度传感器插入实验样品里**少20mm。
• When using metal vessels, do not place the temperature sensors on the bottom of the vessel.
•
当用金属容器时，不要将温度传感器放在金属容器底部。
Placing sensors on the vessel bottom can cause excessively high temperature to be measured especially in media which have poor conductivity. The tip of the measuring sensor must be at least 5mm from the vessel bottom, a distance of 10mm is ideal.
当将传感器置于容器底部时，会导致被测量温度极大的升高，尤其是试验样品导电性低的时候。传感器头部必须离容器底部5mm,10mm是**理想的距离。
• The instrument can only be disconnected from the main power supply by pulling out the mains plug or the connector plug.
• 必须在拔掉主电源插头或者连接器插头时才可以拔掉仪器电源。
• The voltage stated on the label must correspond to the main power supply. •
产品使用电压必须要和主电源电压一致.
• Ensure that the mains power supply cable does not touch the heating base plate. Do not cover the device.
• 确保主电源线不碰触产品加热元件，并且电源线不能缠绕仪器。
• Keep away from high magnetic field.
• 远离强磁区域。
• Observe the minimum distances between the devices, between the device and the wall and above the assembly (min.100mm). •
产品离墙体距离**少100mm.
