This magnetic stirrer is controlled by a single-chip microcomputer, which is an improved version of the company's 08-3 constant temperature magnetic stirrer. It has changed the old tradition of setting with a potentiometer knob, and uses light touch buttons to digitally set stirring speed, heating temperature, timing time, etc. The brushless DC motor drive is maintained, the speed is stable, the temperature control is accurate, and the use is more convenient. Large capacity, high power, suitable for chemical, pharmaceutical, scientific research and other industries.
Instructions
1. Place the stirrer stably, connect the temperature sensor to the two terminals at the back of the machine, place the beaker containing the liquid medicine in the middle of the Heating Plate, and put a stirring bar, insert the temperature sensor into the liquid medicine, plug in the power, and turn on the power The switch, the speed indicator and the temperature indicator are on, the left number shows the original set speed, and the right number shows the original set temperature;
2. Speed setting: press the setting button once, the left number will flash, use the up or down key to set the required speed;
3. Time setting: press the setting button once, the time indicator light is on, use the up or down button to set the required time, if no timing is required, set the time to "0";
4. Temperature setting: Press the setting button once, the temperature indicator light will be on, and use the up or down button to set the liquid temperature;
5. Temperature difference setting: press the setting button, the temperature difference indicator light is on, use the up or down button to set the required temperature difference value, the temperature difference value is directly related to the maximum temperature of the Heating Plate, the maximum temperature of the Heating Plate = liquid set temperature + temperature difference value + (liquid set temperature - liquid measured temperature) × 2, in the working state of stirring and heating, press the setting button until the temperature difference indicator light is on, the digital display is the temperature of the Heating Plate. The temperature difference value is set according to the amount of stirring, the set temperature of the liquid, the size of the direct contact area between the bottom of the container and the Heating Plate, and other factors;
6. Press the setting button twice, the speed indicator light is on, the left number shows the set speed, the temperature indicator light is on, the right number shows the set temperature, and the setting is completed;
7. Press the stirring button once, the stirring indicator light will be on, and the stirrer will run from slow to fast and reach the set speed;
8. Press the heating button once, the heating indicator light is on, heating starts, and the red temperature rise indicator light is on, indicating that the Heating Plate is powered on and heating;
9. The machine can only be heated when it is stirring. When the heating indicator is on, press the heating button again to stop heating. If you press the stirring button again, both stirring and heating will stop;
10. Display the current status: press the setting button, when the speed, time, and temperature indicators are on, it will display the current speed, remaining time, liquid temperature, etc. (when the heating indicator is off, it will display the set temperature). When the stirrer is in the heating state, press the setting button until the temperature difference indicator light is on, and the surface temperature of the Heating Plate is displayed;
11. When the stirring is stopped, press the stirring key again, and the stirrer will run according to the data set last time; (timing restarts)
12. When the machine is in the working state, press the up or down key to adjust the stirring speed. When the key is pressed, the digital display is the required speed for adjustment. After the key is released, the original display state will be restored. The adjusted stirring speed in the working state, The machine cannot be stored, and when it is turned on next time, it will work at the original stirring speed setting;
13. Except that the stirring speed of this machine can be adjusted under the working state, when other data needs to be newly set, the stirring key needs to be turned off first, and the data can be reset when pressing the setting key to an indicator light that needs to be reset;
14. When the agitator reaches the set time, there will be an alarm sound;
15. When the agitator stops running, the power consumption is very small, if the time is short, it is unnecessary to turn off the power;
Precautions
1. The power outlet should be well grounded;
2. When the machine is in use, the liquid medicine in the beaker should not be too full, so as not to overflow when stirring;
3. The temperature of the Heating Plate is very high when it is working, so the power cord and temperature sensor leads should be kept away from them, let alone touched;
4. If the machine is not used for a long time, it should be unplugged;
