Overview
RONGHUA INSTRUMENT DF-6 Magnetic Stirrer is a multifunctional experimental equipment with triple heating and stirring functions of dry burning, oil bath and water bath. The instrument has good performance, no noise, no vibration and fast heating. It is widely used in experimental work in universities, environmental protection, health, epidemic prevention, petroleum, chemical, medical and other units.
Features
1. With dry burning, oil bath, water bath triple heating stirring function
2. Good performance, no noise, no vibration, fast heating
3.6 station independent temperature control design
4. Wide stirring speed range (starting~ 2600rpm)
5. High temperature control accuracy (+/- 1 ℃)
6. PID self-tuning function
Principle
The Magnetic Stirrer drives the stirrer to swirl/spin in the container through magnetic coupling to achieve uniform stirring of the solution. The heating system provides heat through the heat collector plate, and the temperature is precisely controlled with a thermostat to realize the thermostatic heating and stirring function.
Applications
Universities, environmental protection, health, epidemic prevention, petroleum, chemical, medical units
Steps
1. Check whether the random accessories are complete, install the fixture, and plug in the temperature control Probe.
2. Place the experimental solution in a beaker or flask, put in a stirrer, and place it in the center of the heat collecting plate
3. Plug in the power supply, turn on the power switch, adjust the speed knob to select the desired stirring speed
4. Turn on the heating switch when thermostatic heating is required
5. Press the SET key to set the temperature, and adjust the value through the up and down buttons
6. Press and hold the SET button for 3 seconds to enter the internal parameter settings, and parameters such as Lck, Sc, E, P, c, AL, TI can be adjusted
7. Press the shift button to set the timing in working condition
8. In working state, press and hold the down button for more than 6 seconds to start the PID self-tuning mode
Notice
• Direct starting at high speed is not allowed, so as not to cause the stirrer to jump out of sync
• Parameter c is a reserved parameter within the system, please do not adjust it
• When the P value is 0, enter the breakpoint control mode, and the system PID will fail
• The ALM light flashes in self-tuning mode, press and hold the down button for more than 6 seconds to exit the self-tuning.
• When timer is set to 0, the timing mode is turned off
