Please carefully remove all parts of the digital display constant temperature magnetic stirrer
When using a digital display temperature magnetic stirrer, first check whether random fittings is complete, and then press the packed first order fixture, mix to the beaker on the center of the heating plate, put mixing son need to join solution in the beaker of solution, and then plug in the power supply first, then turn on the switch, the indicator lights, instrument which begin to work, gradually from slow to fast. High speed starting is not allowed. When not working, the power should be cut off. The constant temperature magnetic agitator with digital display should be kept clean and dry, and the solution should not enter the machine. Avoid damage to the main engine, prevent violent vibration.
If the digital display thermostatic magnetic agitator fails, users should learn the necessary maintenance methods, including:
1. If the digital display constant temperature magnetic stirrer is heavily polluted, clean the buttons, contact points and wiring points before maintenance and check whether the external control keys work normally. Many faults are caused by dirt or dust of the equipment.
2. When the digital display constant temperature magnetic agitator is not powered on, it shall first determine whether the buttons, thermal relays, transformers and fuses of the electrical equipment are intact, and then judge the fault reason, and then conduct the test by power, listen to the sound, measure parameters and find out the fault reason, and then start the maintenance.
3. Before removing the digital display and constant temperature magnetic stirrer, it is necessary to carefully check whether there is any significant damage or crack in the equipment, understand its maintenance experience and service life, and then check the inside of the digital display and constant temperature magnetic stirrer.
4, after concluding that there is no problem with the mechanical parts, digital display thermostatic magnetic agitator electrical inspection, circuit fault inspection, to use the detection instrument to find the fault location, if not bad contact, then can be targeted to view the line and mechanical operation relationship, to prevent mistakes.
