Product Usage

The inner pot of the HH-S digital constant temperature oil bath pot is made of high-quality stainless steel plate and carefully processed. The edge wrapping process around the inner pot can prevent liquid infiltration. It has the advantages of high temperature control accuracy, compact structure, beautiful appearance, energy saving, and long service life. It is selected for precision products in experimental science fields such as biology, physics, plants, chemical engineering, medical care, environmental protection, or auxiliary heating.

8. Can contact sales to customize test tube racks and baskets

usage method:

1. First, inject appropriate oil or water into the water tank. At all times, the liquid must be submerged in the heating tube and cannot be burned dry.

2. Safe use of electricity: This product uses a 220V AC power supply, and the power socket should use a three hole safety socket. It must be properly grounded and the grounding wire must not be connected to the gas pipeline.

3. Turn on the power, the instrument panel lights up, and set the desired temperature

1. Set temperature

Press the SET button to enter the temperature setting mode or view the set value. Press the SET button and see the flashing number to indicate that you are in the setting mode. Press the up button to increase the set value and the down button to decrease it. Keep pressing and holding it will continue to increase or decrease to the desired value. Once the setting is complete, press the SET button again to exit the setting mode and return to the normal working measurement mode.

2. Adjust parameters

Sc: Press and hold the SET button for 3 seconds to enter the internal parameter setting adjustment interface. The interface displays Sc as the error calibration value, indicating the error between the measured value and the actual value of the temperature controller. The default value is 0.0. You can press the SET button again to display a flashing number to enter the adjustment state (the parameter setting method is the same below), and press the up or down button to adjust the value. （-99~99）

E: After setting, press the SET key to enter the next parameter adjustment. The interface displays E, which represents the advance amount of breakpoint control (only effective when the P value is set to 0). The default value is 5, and the adjustment method is the same as Sc.

P: Press the SET button again to enter the third parameter, and the interface will display P indicating the set value of P. The meaning of P value is roughly the starting control temperature=set value - (100/P value). If set to 200 degrees, a P value of 100 indicates control starts at 199 degrees, and a P value of 40 indicates adjustment starts at 197.5 degrees. If the temperature overshoot is too high during use, adjust the P value appropriately. If the temperature rises too slowly or cannot reach the control temperature, adjust the P value appropriately.

Note: When the P value is 0, it enters breakpoint control mode. When the system PID fails, heating starts when the temperature is below (set value - E value), otherwise heating stops.

c: Press the SET key to enter the setting of parameter c. The final parameter is temporarily reserved within the system and should not be adjusted. The default value is 50.

AL: Press the SET key to enter the setting of parameter AL, which represents the high temperature alarm value. When the temperature exceeds the set temperature+AL, the instrument will sound a high temperature alarm.

TI: Press the SET key to enter the setting of parameter TI, which represents the timer in minutes. 0 indicates that the timing mode is turned off. Otherwise, when the instrument operates at TI value for minutes, it will enter a stop state and stop the output of the load terminal.

After setting all parameters, press the SET button to save the parameters and return to normal working state.
