Oil Bath Circulator BCOB-101

1. Introduction

1.1 Application

The oil bath is suitable for direct and auxiliary heating in scientific applications requiring precise temperature control, such as biology, chemistry, physics, botany, and chemical engineering.

1.2 Features

This oil tank uses oil as the heating medium. It is specifically designed for the inspection and comparison of glass thermometers, and is suitable for use in laboratories, temperature measurement departments, and thermometer manufacturing factories.

1.3 Performance Characteristics

The temperature control is achieved through digital display instruments, making the operation very convenient:

The temperature adjustment is carried out using a continuous PI.D method, ensuring precise temperature control. The inner container is made of stainless steel, which is durable. The outer shell is made of thin steel plate with plastic coating, and it adopts a forced circulation method of the medium to ensure uniform temperature distribution.

The stainless steel electric heating tubes are selected, which are easy to maintain.

3. Operate

3.1 The order of call-out of each function

Power-on work of the controller:

After the controller is powered on, the monitor Fully lights up, and then the upper limit of the range and the lower limit of the range are displayed. After another 2 seconds, the measurement value is displayed in the upper row, the set value is displayed in the lower row, and enters the standard display mode.

Temperature,Time, wind speed Settings:

Press the SET key, SV flashes, set the temperature, press or key, make the display as the desired temperature value. Press the function key again, the time flashes (unit is minute), set the timing time (if the timing time is not required, the value is 0), press or to display the required time value, and press the function key again, show F(fan), press OR key, so that the display is the required value, then press the function key, the controller returns to standard mode

3.2 Detailed description of each function

PV temperature measurement value; SV Temperature setting value

If " " is displayed, the sensor is open or the input signal exceeds the measurement upper limit. If" "is displayed, the sensor is short-circuited or the input signal is lower than the lower limit of the measuring range. When the input signal of the controller is not within the measuring range, the buzzer buzzes. Press any key to mute the buzzer.

Timer function:

When time is set to 0, the timing function of the controller is cancelled and the controller keeps running. When time is not set to 0, the controller provides the timing function. When the running time of the controller arrives, the lower row displays END, the buzzer chirps, the controller stops working, and press any key to silence, and at the same time Push downKey andKey 4 seconds,it can be restarted.

3.3 Self-toting function of the controller

Long press the key for 4 seconds and then release, the instrument starts the self-setting function, and the running light flashes. When the temperature runs back and forth for several times, the lamp becomes steady on, and the instrument self-setting ends (set the setting time to 0, cancel the timing, and set the timing time again after the end of the self-setting).

3.4 Temperature control parameter setting

In the standard state, long press the SET key, the LCD screen will display LK, adjust LK=18,click the SET key to enter the temperature setting.

5 groups of PID:

Related parameters: segmentation point F1~F4, PID1~PID5

Set the value <= F1, execute PID1

Set value [F1~F2], execute PID2

Set value [Fahrenheit~F3], execute PID3

Set value [Fahrenheit3~Fahrenheit4], execute PID4

Set value > F4, execute PID5

Multiple corrections:

Related parameters PK1 to PK8 are modified in more points.

Modified method, the measured value of the temperature point is directly input to the corresponding PK position.

If a pair of corrected points is no longer needed, the PK is adjusted to the minimum value, which is -1999.

The table below for each functional parameter.
