IIICJJ-4ADigital constant temperature multi head magnetic heating stirrerUsage:

When using this instrument, first check if all the accessories are complete, then install the fixtures in order, place the beaker that needs to be stirred in the center of the plating plate, add the solution, place the stirrer in the beaker solution, and then plug in the power plug of the instrument first. Then turn on the power speed control switch and turn on the indicator light to start working. The speed control is gradually adjusted from low speed to high speed, and it is not allowed to start directly at high speed to avoid the stirrer not being synchronized and causing jumping. When not working, the power should be cut off. To ensure safety, please connect the ground wire when using. The instrument should be kept clean and dry, and it is strictly prohibited for solution to enter the machine to avoid damaging the parts and prevent severe vibration.

4、 Attention:

1When the stirrer jumps or does not stir during mixing, please cut off the power and check if the bottom of the beaker is flat and the position is correct. Please also measure if the current voltage is220Vpositive and negative10VOtherwise, the above situation will occur.
2The heating time should generally not be too long, and intermittent use can prolong the service life.
3Electricity usage: The power socket should use a three hole safety socket and must be properly grounded.

4The instrument should be kept clean and dry, and the solution should strictly flow into the machine to avoid damaging it. When not working, the power should be cut off.

5、 Usage and maintenance:

1Place the test bottle (or other vessel) containing the solution and stirrer on the top plate of the working face. When the fixture needs to be used, adjust and calibrate the height position of the fixture on the column, and correctly clamp it.

2Connect the external power supply, adjust the speed control knob, and raise it to the desired speed.

3Select the constant temperature one by one:

Insert the temperature sensor into the solution and set the temperature as follows:SETThe key can be used to set or view the temperature setpoint. pressSETThe characters on the keyboard and digital display start flashing,Indicates that the instrument has entered the set state,Press the △ key to increase the set value, press the ▽ key to decrease the set value, long press the △ or ▽ key to quickly change the data, and adjust it to the desired temperature,Press againSETThe key instrument panel returns to normal working state and the temperature setting is completed.

The following parameters have been debugged before leaving the factory,Adjust when unable to meet requirements.

pressSETkey3The second meter enters the inner parameter setting state.

E: This parameter isP=0When is the advance amount for heating to stop, whenPnot equal to0The instrument panel is intelligentPIDWorking mode, P is not equal to0The E parameter is meaningless.

P: For the proportional band, which refers to the proportional control value, the instrument operates in PID mode with the set value as the center and the P value distributed on both sides of the set point within the P value range.

T: For the heating output cycle, which is the working cycle of the relay, a small T value has good control effect, but a too small T value will reduce the lifespan of the relay due to frequent operation. The general T value is taken as20－60In seconds.

To simplify the operation, the integration and differentiation time of the instrument are designed as hidden parameters, with their values set as automatic default values.

4Error correction: When confirming that the value displayed on the instrument is not the correct measurement value, the displayed value can be corrected. pressSETkey3Enter the inner menu of the instrument panel in seconds, and the * parameters that appear and flash areE00Advance quantity, press againSETThe parameter where the key appears and flashes is the error correction parameter, which can be modified by using the △ or ▽ key. The range of error correction is-9.9℃ to+9.9℃, press again after the correction is completedSETPress the key to exit. The correction value of the instrument when it leaves the factory is0.0When using, it is necessary to prevent correcting instruments that display correctly to incorrect ones.

4After completing the work, place the speed control knob and temperature setting knob in the smallest position, turn off the power switch, and cut off the power.

5Wipe the top plate, columns, and fixtures of the working face clean, and there should be no water droplets or residue of dirt on them.
