▲: Press to increase the set value in the setting state. Hold to increase continuously.
SET: Press to enter the setting state and to enter a value.

Screen

SV: Displays the parameter value.

3. 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.

4. Temperature and Time Setting

4.1. No Timer Function

Press the SET button to enter the setting state 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 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 ndt 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.

5. Self-tuning of PID

When the temperature control effect is not ideal, a system self-tuning can be carried out where the equipment will automatically configure its PID parameters. To do that, follow the next instructions:

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.

6. 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 Lc; 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.
