Temperature Graph

Note: The specifications mentioned above have been tested in a 25 ºC environment.

Working Conditions

1. Ambient temperature: 5 – 32 ºC (if the set temperature ≦ 10 ºC, ambient ≦ 28 ºC).
2. Humidity: ≦ 80 % RH.
3. Air Pressure: 80 – 106 Kpa.
4. Ensure that the incubator remains stable (avoid shaking movements) and is not exposed to corrosive air.
5. Avoid exposure to light and maintain a controlled temperature environment.
6. Maintain a clear distance from dust, install the equipment horizontally, and ensure there is adequate space between the equipment and the wall.

Safety Information

1. Upon receiving the equipment, to prevent compressor damage due to extended transportation, please allow the machine to stand still for one day before use. Ensure equipment safety by installing external protection and supplying power as required.
2. Avoid testing flammable, combustible, poisonous, or corrosive materials.
3. Install the equipment horizontally.
4. Disassembly and repair of the equipment should only be carried out by trained personnel.
5. If adding additional equipment to the chamber with a power consumption exceeding 2A, connect the power externally; do not use the equipment’s internal power.
6. When the chamber temperature is ≧ 50 ºC, refrain from setting low-temperature settings to ensure the compressor’s long-term usability.
7. Prior to operating the equipment, all users must read this manual.

Operation Cautions

1. There is a test hole at the top of the incubator. If you need to add additional equipment inside the chamber, please use this hole.
2. If there is no need for U.V. light, turn off the U.V. lamp to avoid affecting the temperature.
3. Before activating the cooling function, dry the chamber for 1 hour at 50 ºC.
4. The chamber utilizes a vertical air circulation system. Do not overload the shelves with materials; the test material should occupy less than 1/3 of each shelf.
5. When the test environment exceeds 35 ºC or the set temperature is above 50 ºC, refrain from setting the low-temperature option.
6. Clean the chamber and the machine’s surface with pure water. When the machine is not in use, please disconnect the power supply, ensuring both the interior and exterior are clean and dry.

Controller Operation Instructions

1. Controller Specifications

   • Temperature setting range: 0.0 – 60.0 ºC
   • Timer setting range: 0 – 99 minutes 59 seconds
   • Display error: < 0.5 %
   • Sensor: PT100

2. Panel Instructions

3. Temperature-Time Operation
   Example: setting the temperature to 30 ºC. Once reached, stop the instrument 5 hours later (T = 30 ºC; timer = 5 hours).

4. Click the set button to enter the temperature setting mode and set the temperature to 30 ºC using the up and down keys.

5. Click the set button to enter the timer setting mode, change the hours from “0” to “5” using the up and down keys. Once you need to set the minutes, follow the same steps.
   When the timer is set to “0”, it means there is no timing function, and the incubator runs continuously.
   When the timer is not set to “0”, once the inner chamber temperature reaches the set temperature, the timer will start. When the time expires, the machine will stop. When it stops, the light will turn on, and the buzzer will sound for 30 seconds. Press the down key for 4 seconds, and the system will start working again. When the buzzer sounds, press any key to stop the sound.

6. Illumination: click the illumination button to turn it on and click it again to turn it off.

7. Inner Chamber Specification Setting
   Press the set button for more than 3 seconds, and the screen will display “LC.” Change the number to “3” using the up and down keys, then click the set button again to access the parameters. By clicking the set button, you can navigate through the parameters in the following table and modify each specification. Press the set button for 3 seconds to exit the settings; the specifications will be saved automatically. If no button is pressed for 30 seconds, it will exit the settings automatically without saving the specifications.

Note:

1. To ensure precise results, you can adjust P (within the range of 10.0 – 20.0), but generally, it should not require any changes. Please use the factory specifications.
2. If there is a display error, typically, you should adjust Pb and not PK.
