Rechargable Temperature Data Logger with USB Interface

This standalone data logger measures and stores up to 32,510 temperature readings over a -20 to +60° (-4 to +140°F) measurement range. The polycarbonate window and stainless steel 316 assembly provide protection from corrosion, impact and water ingree to IP67 / NEMA 4X. The unit is powered by a lithium-ion recharable battery which allows logging for up to 1 month. Setup and downloading is completed by connecting the data logger to a PC's USB port using the supplied cable and running the purpose designed software under Windows 2000, XP, Vista and Windows 7. Correct functioning of the unit is indicated by flashing red and green LEDs. Downloaded data can then be graphed, printed and exported to other applications.

LED Status Indication

EL-USB-1-RCG features two LEDs that indicate the logging, battery and alarm status:

• The first LED flashes red (R) to indicate that the EL-USB-1-RCG is in an alarm condition. It will flash when the logged temperature has exceeded a Low or High alarm level.
• The second LEd flashes green (G) to indicate that the EL-USB-1-RCG is not in an alarm condition. Latching is enabled by default, which forces the logger to continue flashing the red LED after an alarm, even when the temperature has returned to normal. This feature ensures that the user is notified than an alarm level has been exceeded, without the need to download the data from the logger.

Latching can be turned off via the control software. The red LED will then only flash whilst the logger is in an alarm condition. When the temperature returns to normal, the green LED will flash.

Additional LED modes are explained below:

Battery Charging

The logger is fitted with a 280mAh capacitiy (nominal) rechareable Lithium-Ion battery. The logger must be connected to an active USB port to recharge the battery; this may take up to 5 hours, depending on the level of discharge. The battery charge status is indicated by the status LED's. The red LED indicates that chargin is ongoing; the green LED indicates that the battery has a full charge.

Like all rechargeable batteries, the fully charged capacity reduces over time. The battery operates best at temperatures of 10°C to 30°C (50°F to 86°F). Recharing should only be performed within this temperature range.

* @-20°C(-4°F), 1 second logging rate
** @-20°C(68°F), 1 minutes logging rate

EasyLog Software

The core of Lascar's data logging solution is the free software supplied with each data logger. Using a wizard format to guide the user through setup of the data logger and subsequent download of collected data, the software puts the 'easy' into EasyLog.

Features

• Collects and stores data from at least 500 data loggers
• View downloaded data with general trend and summary screens
• Allows full or quick set-up of compatible EasyLog USB data loggers
• Touch screen interface for navigation of menus
• 2.8” TFT display
• Stored data can be transferred to a PC/Mac via micro USB cable
• Use Lascar’s EasyLog USB software on a PC to graph data and export to Excel
• Integral rechargeable lithium battery provides up to 8 hours use (nominal)

The EL-DataPad allows users of Lascar’s EL-USB data loggers to configure their units and download data and view logging results on-thespot rather than removing the logger from the environment being measured and taking it to their PC. This allows continual logging with shorter breaks in data collection, less travel for the user, on-site data collection in graph, legend and summary format and the ability for users to reconfigure loggers in ‘the field’.

The logger is connected to the EL-DataPad via a standard USB port at the top of the viewer. Once connected, the user is guided through a simple touchscreen menu with options to Set-Up Logger, Stop Logger & Download and View Data. On-screen instructions follow the same structure as Lascar’s EL-USB-WIN software for PC currently provided with each data logger.

Data from up to 100 loggers can be viewed on the EL-DataPad, with data from a further 400 units stored on the unit at any one time. Data can be transferred to a PC or Mac using a micro USB cable supplied with the unit. Once uploaded, data is saved in comma separated variable (csv) format, making it suitable for import into spreadsheet packages such as Microsoft Excel or graphed on a PC using Lascar’s EL-WIN-USB software .

The EL-DataPad is compatible with the following EL-USB data loggers: EL-USB-1, EL-USB-1-LCD, EL-USB-1-PRO, EL-USB-2, EL-USB-2+, EL-USB-2-LCD, EL-USB-2-LCD+, EL-USB-TC, EL-USB-TC-LCD, EL-USB-LITE.
