Safety Instructions

| Connect the device to an earthed socket to ensure the safety of the machine and the experiment. Make sure the voltage is the same as required by the device.
---|---
| The use of this instrument in flammable, explosive, poisonous, or highly corrosive environments or with hazardous substances is forbidden.
| Place the incubator on a horizontal, flat, clean, non-slip and stable surface. Adjust the feet so that the device is leveled.
| This item must only be used by qualified staff that has read the instructions manual and knows how to operate it.
| Do not place the device near any heat source. Keep away from high magnetic fields. Do not put volatile, flammable and explosive materials in the machine, otherwise it could cause an explosion or a fire.
| Non-professionals must not disassemble or repair this machine.
| Read the instructions manual before using this device.

When working, wear the necessary personal protective equipment to avoid the risk of:
– Burns caused by contact with hot surfaces or materials
– Burns caused by splashing and evaporation of liquids
– Intoxication caused by release of toxic or flammable gases.
Set up the instrument on a spacious, stable, clean, non-slip, dry, and fireproof surface that can support the weight of the equipment. Do not operate the instrument in explosive atmospheres or with hazardous substances.
During use, do not touch the heating pipe with your hands as it could cause burns.
The temperature must be set at least 25ºC below the flash point of the substances used.
Process pathogenic materials only in closed vessels.
Beware of hazards due to:
– Flammable materials or media with a low boiling temperature
– Overfilling of the vessel
– Unsafe vessels
The instrument can only be disconnected from the main power supply by pulling from the plug, not the cable.
Check the instrument and accessories before handling for damage prior to every use. 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 the assembly or disassembly of accessories.
The voltage stated on the label must correspond to the main power supply.
Ensure that the mains cable does not touch the heating base.
Do not cover the device.
Keep away from high magnetic fields.
Pay attention to the temperature setting. Never leave the equipment unattended while the heating function is ON.

Product description

2.1. Summary
This product is suitable for distillation, concentration, drying and thermostatic heating in medical units, universities and schools, scientific research units, and laboratories of industrial and mining enterprises like chemical painting and dyeing enterprises or pharmaceutical enterprises.

2.2. Structure features
– The innovative design structure that effectively prevents steam leakage.
– Intelligent temperature control instrument with high-brightness digital display and touch key that allows simple operation and high-precision temperature control.
– The shell, interior and cover of the product are all made of transparent engineering plastics which allow to clearly see the object that is being heated.
2.3. Cleaning and maintenance
– Before use, add water until it reaches the clapboard, then connect to the power supply and heat up. Samples cannot be heated without sufficient water.
– The equipment must be used only when the resistor is covered by water; doing otherwise will harm the resistor.
– Avoid violent vibration, collisions, and keep away from corrosive gas.
– After use, empty the tank, dry it, and clean it. Proper maintenance could lengthen the device’s working lifetime.
– Do not spray cleanser directly onto the device.
– If sent in for repair, clean, disinfect and pack it in its original packaging before shipping.

Operation

Place the water bath on a stable surface that can support the weight of the device and leave 30 cm clear on each side.
Fill the tank to 2/3 of the total volume.
Connect to a power supply that is consistent with the voltage requirement of this instrument. Make sure it is properly earthed.
Switch the device on. The power supply indicator will light up.
Set the desired temperature (see instructions below). The temperature controller will display the temperature inside the working chamber.
If desired, set the time (see instructions below).

Note: The thermostatic bath cannot be used with deionized, demineralized or distilled water as it will not conduct electricity properly

Temperature and time setting

4.1. No timer function

Press the SET button to enter the setting state → the indicator SP and the temperature set value will show.
Use ◄ ▼▲ to modify the value.
Press SET to enter → the controller will return to the normal display and the value will be saved

4.2. Timer function

Press SET to enter the setting state → the indicator SP and the temperature set value will show.
Press SET again → the indicator SP and the time set value will show.
Use ◄ ▼▲ to modify the value.
Press SET to return to the initial screen. The value will be saved automatically.

When the time is set to 0, the controller will run continuously until manually stopped.
Otherwise, when the timer is set, the lower window will display the temperature set value or the running time depending on the ntd parameter configuration (see later). When the time is over, the lower window will display End and the alarm will go off and ring for 60s. Stop it by pressing any button. Press the RST button for 3s to restart the controller.

Self-tuning of PID

When the temperature control effect is not ideal, a system self-tuning can be caried out where the equipment will automatically configurate its PID parameters. To do that, follow the next instructions:r
– Press AT for 6s → the controller will run the auto-tuning function. The AT indicator will flash.
– To stop the process, press AT for 6s while it is running.
– During the process, the SET button does not work, and the lower window always displays the temperature set value.

Internal parameters setting

6.1. How to enter

To adjust the internal parameters, you must enter the required password. To do that, follow these instructions:

Press SET for 3s → the controller will display the password prompt Lc.
Use ◄ ▼▲ to choose the required value (see the password values below).
Press SET to enter → the controller will enter the internal parameters setting state.

To return to the regular state at any time, press SET for 3s.
