4. 설정
4.1 소프트웨어 설치
Before using the data logger, you must install the EasyLog 21CFR software on your computer. This software is required for configuring the logger, downloading data, and view그래프를 그리다.
- Obtain the EasyLog 21CFR software from the manufacturer's official web사이트 또는 제공된 설치 미디어를 참조하세요.
- 화면의 지시에 따라 소프트웨어 설치를 완료하십시오.
- 컴퓨터가 소프트웨어의 최소 시스템 요구 사항을 충족하는지 확인하십시오.
4.2 초기 구성
Once the software is installed, connect the data logger to your computer via the USB port.
- Remove the protective cap from the USB connector of the data logger.
- Plug the data logger into an available USB port on your computer.
- Launch the EasyLog 21CFR software. The software should detect the connected data logger.
- Within the software, configure the desired logging parameters, including:
- Logging rate (e.g., every 10 minutes, every hour)
- Start mode (e.g., immediate, delayed start, push-button start)
- 경보 임계값(고온 및 저온 한계)
- Units of measurement (°C or °F)
- Apply the settings to the data logger. The logger is now ready for deployment.
4.3 프로브 연결
Connect the thermistor probe to the designated input port on the data logger. Ensure a secure connection for accurate readings.
5. 운영
5.1 데이터 로깅 시작
The method for starting data logging depends on the configuration set in the software:
- 즉시 시작: Logging begins as soon as the settings are applied from the software.
- 지연된 시작: Logging begins after a pre-set time delay.
- 푸시 버튼 시작: Press and hold the push-button on the data logger for approximately 3 seconds until the 'REC' indicator appears on the LCD.
5.2 Viewing Readings on LCD
Press the push-button briefly to cycle through the displayed information on the LCD:
- 현재 온도: The real-time temperature reading from the probe.
- Highest Recorded Temperature: The maximum temperature recorded during the current logging session.
- Lowest Recorded Temperature: The minimum temperature recorded during the current logging session.
- 로깅 상태: Indicators such as 'REC' (recording), 'STOP' (stopped), 'FULL' (memory full).
5.3 데이터 로깅 중지
Logging can be stopped in several ways, depending on the configuration:
- 메모리 용량 부족: Logging automatically stops when the device's memory capacity (32,000 readings) is reached.
- Push-Button Stop: If configured, press and hold the push-button for approximately 3 seconds until the 'STOP' indicator appears.
- 소프트웨어를 통해: Connect the logger to a computer and use the EasyLog 21CFR software to stop the logging session.
5.4 데이터 다운로드
기록된 데이터를 검색하려면:
- 데이터 로거를 USB 케이블로 컴퓨터에 연결하세요.
- Open the EasyLog 21CFR software.
- The software will automatically detect the logger and prompt you to download the data.
- Follow the software instructions to save the data, which can then be viewed, analyzed, and exported in various formats.
6. 유지관리
6.1 청소
데이터 로거의 외부를 부드러운 천으로 닦으십시오.amp cloth. Do not use abrasive cleaners or solvents. Ensure the USB port and probe input are free from dust and debris.
6.2 배터리 교체
The data logger contains an internal battery. If the battery indicator on the LCD or software shows low power, the battery may need replacement. Refer to the EasyLog 21CFR software documentation or contact customer support for battery replacement procedures, as this may require specialized tools or service.
6.3 교정
For applications requiring high accuracy and compliance, periodic calibration of the data logger and its probe is recommended. Consult the manufacturer's guidelines or a certified calibration service for details.
