3、 Usage:
1. First, pour clean water into the pot At any time, water must be submerged in the heating tube and cannot be burned dry
2. Insert the power plug into the three eye power socket to ensure safety;
3. Turn on the power switch, the digital display light will turn on, press the preset button, adjust the temperature knob to the desired temperature, and then press the preset button to the actual measurement position. At this point, the digital display temperature will be the actual temperature. When the preset temperature is reached, the constant temperature light will turn on, indicating constant temperature
4. Keeping the water clean can extend its lifespan.
4、 Attention:
1. To ensure your personal safety, please use a three-phase safety socket and ensure proper grounding when using it.
2. The instrument should be kept clean during use. If not in use for a long time, the power should be cut off and the switch should be turned off to avoid accidents.
3. Stainless steel container without water added, please do not turn on the temperature control switch to avoid damage to the electric heating tube and thermostat
4. Please read the instructions carefully before using this instrument to avoid unnecessary trouble.
5、 1 holethermostat water bathAttachment (Instrument Usage):
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 and 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 following parameter setting method is the same), and press the up or down button to adjust the value. (-9.9~9.9)
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 0.5, 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 - (10/P value). If set to 50 degrees, a P value of 10 indicates control starts at 49 degrees, and a P value of 4 indicates adjustment starts at 47.5 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.

6、 Common faults and troubleshooting:
Serial Number | fault conditions | 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 0.0 | Thermistor short circuit or temperature exceeding lower limit |
4 | Consistently displaying 99.9 | Thermistor open circuit, not connected properly, or temperature exceeding upper limit |
5 | Large temperature overshoot | 1. The P value is too large, 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. Heating device power too low or temperature probe 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 |
