01Summary
BBWA 100 Series Water Bath is applicable for distillation, concentration, drying and thermostatic
heating of medical units, universities and colleges, scientic research units and laboratories of
industrial and mining enterprises like chemical printing and dyeing enterprises and pharmaceutical
enterprises.
02Structure features
1. The enclosure of the product is formed and machined by using high-quality steel plate. Static
electric spraying process is adopted on the surface, which is sturdy and durable.
2. The liner and upper cover are made of high-quality stainless steel plate, featuring strong corrosion
resistance.
3. U-shaped heating pipe is adopted for direct heating in water. The temperature rise is quick and the
thermal loss is small.
4. Single-row digital display or intelligent temperature controller boasts simple operation and
favorable application eect.

04Working Conditions
1. Temperature ranges between 5~40°C;
2. Relative humidity less than 85% RH;
3. Power: voltage 220-240v, frequency 50-60Hz;
4. No violent vibration and corrosive gas surround the equipment.
05Attentions
1. Before use, add water 50mm until the water reaches above the clapboard, then connect to power
supply and heat. It is not allowed to heat with insucient water.
2. During use, do not touch the heating pipe by your hands to avoid being scalded.
3. After use, timely discharge the water, dry it and keep it clean in order to extend the service life.

i. Meter panel instruction
1. Function key
2. Decrease key-Automatic tuning
3. Add key-Power-on duration
4. Master control output indicator light
5. Automatic tuning indicator light
6. Upper limit alarm indicator light
7. Measured value display window
8. Set value display window
ii. Instrument automatic tuning function
Press ▼ for 5 seconds and the automatic tuning AT light starts ashing automatically. After the
automatic tuning process is completed, AT light is o and a group of PID parameters overcoming
overheating is obtained. During the automatic tuning process, press ▼ for 5 seconds and AT light
is o. Then, the automatic tuning process is stopped. The instrument will control according to the
original PID parameters. If you feel the temperature rise is too slow, you may adopt the automatically
tuned parameter with the temperature several degrees higher to control the required time and speed.
iii. Time function
Press ▲ for 10 seconds and the total power-on duration is displayed in minutes. It will be automatically
recovered after 5 seconds.
iv. Timing setting function
Set the time minutes according to in the second menu of Parameter Setting Table When the time
required by the instrument reaches the rear lower row, the display is o and the output function
stops.
If the set control time is to be recovered, the product shall be shut down rst and then powered on
and started again. When the setting is 0, the instrument will cancel the timing function and output
continuously.

If LLL is displayed, it indicates that the sensor is short-circuited or the temperature is lower than the
measured lower limit.
If HHH is displayed, it indicates that the sensor is open-circuited or the temperature is greater than

the measured upper limit. Note: when time function is used, pay attention to power failure. If power
failure already exists, the previous timing becomes invalid. When the power supply is recovered, the
timing is restarted from zero.

08Operation
1. The water bath shall be placed on a stable platform.
2. Add water to 50mm above the clapboard before use.
3. Connect to a power supply consistent with the requirement of this instrument and reliably ground
the grounding terminals of the socket of power supply used.
4. Open the power switch and the power supply indicator light is on. Set the required temperature,
and the temperature controller begins to display the temperature inside the working chamber.
Refer to the instructions of temperature controller for digital temperature controller and intelligent
temperature controller.
After the set temperature is reached and it is automatically put under a constant temperature for half
an hour, it will be put in the sample tube. The experiment is completed. Then, close the power switch
and take out the sample tube.
