Overview

DB-1-2-3-4 stainless steel electric heating plate is widely used for sample baking, drying, and other temperature tests. It is a tool for biology, genetics, medicine and health, environmental protection, biochemical laboratories, analysis rooms, education and scientific research.

Product Details

　　DB-1-2-3-4 stainless steel electric heating plateIt is a small constant temperature equipment produced according to the needs of various universities, research institutions, hospitals, and animal husbandry, which is durable and corrosion-resistant. Especially in animal husbandry, when conducting artificial insemination, multiple glass pieces can be placed on top for insulation, which will not freeze the sperm to death and improve the accuracy of the experiment. It is a good helper for the staff.

　　1： Technical indicators:

Power supply: 220V ± 10V 50HZ Temperature control range: Room temperature+5-300 ℃ Temperature control accuracy: ≤± 2 ℃

Working size: (mm) 250 × 200 Power: 600W-800W Usage time: Can be used continuously

　　2、 Usage:

1: Connect the power and turn on the power switch.

2. 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.

3. 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 the (set value - E value), otherwise heating stops.

C: Press the SET key to enter the setting of parameter C. The parameter after 'zui' is temporarily reserved for internal use in the system. Please do not adjust it. 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.

III Common faults and troubleshooting

serial number	fault condition	Reasons and exclusions
1	Display normal but not heating up	The set temperature is lower than the measured temperature.
2	The heating light is on but not heating up	1. Output terminal connection failure, or heating working device failure 2, connection failure between control board and power board
3	Always displaying room temperature	Probe short circuit
4	Always displaying 999	Probe open circuit, not connected properly, or temperature exceeding the upper limit
5	Large temperature overshoot	1. The P value is too high, adjust it appropriately. 2. The temperature probe is too close to the heating element
6	The heating rate is very slow	1. The P value is too small, adjust it appropriately. 2. The power of the heating element is too small or the temperature probe is too far away
7	Unstable temperature fluctuations	P value is too high or C value is too low
8	Slow temperature response	The C value is too high, lower it appropriately
9	Large temperature display error	Temperature probe malfunction or incorrect probe position
10	Small temperature display error	System error, adjust SC value

　　
4 Indicator light information:

HEAT light: The one on the left is the heating indicator light, which is on to indicate heating and off to indicate stopping heating. TIME light: The middle is the timer light, off indicates that the timer is turned off, flashing

Shuo indicates that the timer is on and working, while constant light indicates that the timer is on and the time has passed, and the instrument is in a stopped output state. ALT light: high temperature alarm light, on indicates high temperature

Exceeding the limit and extinguishing indicates that there is no excessive high temperature.

Five noteImportant matters:Due to the use of low-power heating, this instrument takes a long time to heat up. It takes about 5-10 minutes to initially heat up to the temperature you need.
