This document describes the Steinberg Systems Data Logger, a device designed for precise and reliable measurement and recording of temperature and humidity data. It is a versatile tool suitable for various applications where environmental conditions need to be monitored and documented. The device is manufactured in accordance with strict technological guidelines, using state-of-the-art technologies and components, and adheres to international quality standards.
Function Description
The Steinberg Systems Data Logger is primarily used to measure and record temperature and humidity. It functions as a data logger, storing collected data internally for later retrieval and analysis. The device is capable of continuous monitoring over extended periods, making it suitable for long-term environmental studies, quality control, and compliance with specific regulations. The collected data can be downloaded to a computer for detailed analysis, visualization, and reporting using dedicated software. The software allows users to configure the logger settings, view real-time data, generate graphs and tables, and export data in various formats. It also supports features like alarm settings for out-of-range measurements and digital signatures for data integrity, which is particularly relevant for applications requiring compliance with regulations like FDA 21 CFR Part 11.

Usage Features
The data logger is designed for user-friendly operation with a clear display and intuitive controls.
- Display and Indicators: The device features an LCD display that shows current readings, battery status, maximum/minimum values, and other relevant information. LED indicators provide visual feedback on the device's status, such as active recording, alarms, and battery low warnings.
- Button Controls: Buttons on the device allow users to start/stop recording, view maximum/minimum values, and navigate through display modes.
- Software Configuration: The accompanying PC software, "Data Logger Graph," is essential for configuring the logger's settings. Users can set the sampling interval, define alarm thresholds, calibrate the device, and set up recording modes (e.g., continuous, start/stop).
- Data Download and Analysis: Data is downloaded via a USB connection to a computer. The software provides comprehensive tools for data analysis, including graphical representation of temperature and humidity trends, tabular data views, and statistical summaries (min, max, average, standard deviation).
- Alarm Functions: Users can set upper and lower alarm limits for both temperature and humidity. If measurements exceed these limits, the device's LEDs will flash, and an alarm icon will appear on the display.
- Digital Signature and FDA 21 CFR Part 11 Compliance: For regulated environments, the software supports digital signatures, audit trails, and user management features to comply with FDA 21 CFR Part 11 regulations, ensuring data integrity and traceability.
- Multi-Language Support: The software and manual are available in multiple languages, including German, English, Polish, Czech, French, Italian, and Spanish, making it accessible to a broad user base.
- Operating System Compatibility: The software is compatible with Windows XP/Vista/7/8 (32-bit or 64-bit) and requires Microsoft .NET Framework 4.0 or above.
Maintenance Features
The Steinberg Systems Data Logger is designed for minimal maintenance, focusing on reliability and longevity.
- Battery Replacement: The battery life varies by model. For SBS-DL-123/123L, the lithium battery is long-lasting and typically does not require frequent replacement. For SBS-DL-123D/123E, AAA batteries are user-replaceable. Regular checks of the battery status via the display or software are recommended to ensure continuous operation.
- Cleaning: The device should be cleaned with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the casing or display.
- Software Updates: Periodically check for software updates from the manufacturer's website to ensure optimal performance, access new features, and maintain compatibility with evolving operating systems.
- Storage: When not in use for extended periods, store the data logger in a cool, dry place, away from direct sunlight and extreme temperatures, to prolong its lifespan.
- Disposal: The device is an electronic product and must be disposed of according to local regulations for electronic waste. It should not be discarded with household waste. The manufacturer provides information on environmentally friendly disposal and recycling.
