3： Safety instructions for use

To use this product, please read all user manuals and remember to follow the following safety precautions:

1The electrical rated parameters of the socket provided by the user should not be less than the electrical rated parameters of the machine and have good grounding measures.

2When replacing the fuse, the plug should be unplugged from the socket.

3After a circuit or electrical equipment malfunction, it should be repaired by professionals. Using accessories not recommended by the manufacturer can cause certain quality problems.

4. When used in an environment with children, close attention should be paid.

1. When cleaning the machine, the power should be unplugged first

6. All kinds of solutions are strictly prohibited from entering the control room to avoid damaging the host.

4、 Usage method

Connect the power and turn on the power switch.

1Set temperature:

pressSETPress the key to enter the temperature setting mode or view the set valueSETPressing the up button to increase the setting value and the down button to decrease the setting value indicates that the number is flashing in the setting mode. Holding down the button will keep increasing or decreasing to the value you need. Once the setting is complete, press againSETPress the button to exit the setting mode and return to the normal working measurement mode.

2Adjust parameters

Sc:pressSETkey3After holding for a second, enter the internal parameter setting adjustment interface, and the interface will displayScIt is the error calibration value, which represents the error between the measured value and the actual value of the temperature controller. The default value is0.0You can press againSETPress the key to display flashing numbers and enter the adjustment state (the same parameter setting method below). Press the up or down button to adjust the value. （-9.9~9.9）

E:After setting, pressSETPress the key to enter the next parameter adjustment, and the interface will displayEIndicate the advance amount of breakpoint control (only when)PThe value is set to0When effective, the default value is0.5Adjustment methods andScSame thing.

P:Press againSETPress the key to enter the third parameter, and the interface will displayPexpressPValue setting,PThe general meaning of value is Start temperature control=set value-（10/PValue). If set as50Degree,Pvalue10Time represents49Start controlling the degree,Pfor4Time represents47.5Start adjusting the degree. If the temperature is too high during use, it willPAdjust the value appropriately. If the temperature rises too slowly or cannot reach the control temperature, it willPAdjust the 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:pressSETKey to enter parameterscThe settings are temporarily reserved within the system, please do not adjust them. The default value is10.0.

AL:pressSETKey to enter parametersALThe settings,ALIndicates the high temperature alarm value. When the temperature>set temperature+ALAt that time, the instrument triggered a high temperature alarm.

TI:pressSETKey to enter parametersTIThe settings,TIRepresents a timer, measured in minutes.0Indicates that the timed mode is turned off, otherwise when the instrument is workingTIAfter a few minutes, enter the stop state and stop the output of the load terminal.

All parameters have been set, pressSETKey, save parameters and return to normal working state.

Five 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	1Output terminal connection failure, or heating working device failure 2The connection between the control board and the power board is faulty
3	Always displaying 0.0	Thermistor short circuit or temperature exceeding the lower limit
4	Consistently displaying 99.9	Thermistor 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	PThe value is too high or the C value is too low
8	Slow temperature response	CThe value is too high, lower the C value appropriately
9	Large temperature display error	Temperature probe malfunction or incorrect probe position
10	Small temperature display error	System error, adjust SC value

six.Instruction information:

HEATLamp: The one on the left is the heating indicator light, which is on to indicate heating and off to indicate stopping heating.

TIMELamp: The timer light is in the middle, off indicates that the timer is turned off, and flashing indicates that the timer is turned on and working,

Constant light indicates that the timer is on and the time has expired, and the instrument is in a stopped output state.

ALMLamp: High temperature alarm light, on indicates high temperature exceeding limit, off indicates no high temperature exceeding limit.

Upper digital tube: temperature control display

Lower row digital display: displays timed time,OnIndicates timer off, normally open mode,OFFFlashing indicates that the timer has expired, the output is turned off, and the number represents the remaining minutes of the timer.

eighty percent..Maintenance

1. Wipe the working surface of the heating plate clean, and there should be no water droplets, dirt, scale or other foreign objects left on it.
2. Place sample bottles or other containers for testing.
3. Connect the external power supply, turn on the power switch, the indicator light will turn on, and the electric heating plate will be in working condition.
4. After the working surface cools down, press3-5.5-1Request cleaning.
