EL-SIE-2

Temperature and Humidity USB Data Logger,

EasyLog Cloud Compable

Monitor the environment you live and work in with the EasyLog EL-SIE-2. Conguraon is simple, with no soware to install

on your PC or Mac – just connect the logger with a USB cable, and use your standard web browser to congure the device for

logging. You don’t even need internet access to set up and use the EL-SIE-2, it really couldn’t be easier.

The logging interval can be set between 10 seconds and 24 hours, with immediate, delayed, triggered or push-to-start logging.

Alarms are fully user congurable, with funconality including cumulave alarms, pre-alarms, a delay before alarm triggering,

and an alarm hold opon, which connues showing the alarm condion even if the reading returns to an acceptable level.

The display shows current, maximum and minimum readings, and three coloured LEDs indicate device status at a glance.

Once logging is complete, re-connect to your computer and use your browser to view, analyse and save your data. You can also

choose to upload your data to an Easy Log Cloud account, making the data accessible online for powerful graphing, analysis and

report generaon.

Usage Features

Display and LED Indicators: The EL-SIE-2 features a high-contrast LCD display that shows current, maximum, and minimum readings for both temperature and humidity. It also displays the logging status, alarm status, battery level, and channel number. Three LEDs (green, yellow, red) provide visual indications of the device's status, such as active logging, alarms, memory full, or low battery.

Configuration and Data Access: The device can be configured using the free EasyLog software on a PC or Mac. This software allows users to set logging intervals, start modes (immediate, delayed, push-to-start, triggered), and alarm thresholds. Once configured, the logger can operate independently. Data can be downloaded via USB, and the EasyLog Cloud service provides a web-based platform for viewing, analyzing, and managing data from anywhere. The cloud service offers features like data sharing, email alerts, and advanced reporting.

Logging Modes:

Immediate Start: Logging begins as soon as the device is configured and started.
Delayed Start: Logging begins after a specified time.
Push-to-Start: Logging begins when the "Push to Start" button is pressed.
Triggered Start: Logging begins when a specified temperature or humidity threshold is met.

Button Functions: The EL-SIE-2 has multiple buttons that allow for interaction with the device without a computer. These buttons enable users to:

Start and stop logging.
View current, minimum, and maximum readings.
Mute the alarm sounder.
Acknowledge audit marks.
Navigate through display screens and control other functions.

Alarm Management: The device supports programmable high and low alarms for both temperature and humidity. When an alarm threshold is exceeded, the device will display an alarm status on the LCD and illuminate the red LED. An audible alarm sounder can also be enabled to alert users to critical conditions.

Software and Cloud Integration: The EasyLog software provides a user-friendly interface for configuring the logger, viewing data in graphical format, and exporting data to various file types (e.g., CSV, PDF). The EasyLog Cloud service extends functionality by offering:

Remote Access: View live data and historical logs from any internet-connected device.
Data Sharing: Share data with other users or teams.
Email Alerts: Receive notifications when alarms are triggered or other events occur.
Reporting: Generate comprehensive reports for compliance and analysis.

Maintenance Features

Battery Replacement: The EL-SIE-2 uses two standard AAA 1.5V alkaline batteries, which are user-replaceable. The device is designed to retain logged data even when the batteries are depleted or removed, ensuring no loss of critical information during battery changes. The software provides an indication of battery life, allowing users to plan replacements proactively.

Calibration: The device is supplied with a traceable calibration certificate, which is essential for maintaining accuracy and compliance in regulated environments. Regular recalibration is recommended to ensure continued accuracy over time. Lascar Electronics offers calibration services, and information on these services can be found on their website.

Cleaning: The EL-SIE-2 is designed for durability, but it is important to keep the device clean to ensure optimal performance. The manual recommends cleaning the device with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the casing or display.

Firmware Updates: Firmware updates may be released periodically to improve functionality, address bugs, or add new features. These updates can typically be applied using the EasyLog software, ensuring the device remains up-to-date with the latest enhancements.

Environmental Considerations: While the EL-SIE-2 is robust, it is important to operate and store it within its specified environmental ranges to prevent damage and ensure accurate readings. Avoid exposing the device to extreme temperatures, high humidity outside its operating range, or direct sunlight for prolonged periods.

The EL-SIE-2 is a versatile and reliable data logger that combines ease of use with powerful features, making it an excellent choice for anyone needing to monitor temperature and humidity accurately and efficiently.
