This standalone data logger measures and stores more than 32,000 temperature readings over a -20 to +60°C (-4 to +140°F) range with a resolution of 0.1°C (0.2°F). 

The polycarbonate window and stainless steel 316 assembly provides protection from corrosion, impact and water ingress to IP67/NEMA 4X. 

The user can easily set up the logger and view downloaded data by connecting the data logger to a PC’s USB port and using the free EasyLog software. Data can then be graphed, printed and exported to other applications for detailed analysis. 

The data logger is powered by a Lithium-Ion battery which can typically allow for logging for up to 1 month.

## LED STATUS INDICATION 

EL-USB-1-RCG features two LEDs: 

- The first LED flashes **red** 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** to indicate that the EL-USB-1-RCG is not in an alarm condition. 

Using EL-WIN-USB it is possible to set the alarm to remain active even if the reading has returned to normal, in which case the alarm LED will continue to flash red. This ‘Hold’ feature in the software ensures the user is notified that at some point an alarm level has been exceeded, without needing to download the data. 

Hold is enabled by default, and 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.

Easy to install and use, the control software  is compatible with 32-bit and 64-bit versions of Windows 7, 8 & 10. The software is used to set up the logger, download, graph and annotate data or export in Excel, PDF and jpeg formats. 

The software allows the following parameters to be configured: ▪  Logger name ▪  Measurement parameter (°C or °F) ▪  Logging rate (user selectable between 1 second and 12 hours) ▪  High and low alarms ▪  Immediate and delayed logging start **Download the latest version of the software free of charge from www.easylogusb.com** 

## BATTERY INFORMATION 

The EL-USB-1-RCG is fitted with a 280mAh capacity (nominal) rechargeable 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 LEDs. The red LED indicates that charging is ongoing; the green LED indicates that the battery is fully charged. The fully charged capacity of the rechargeable battery will reduce over time. The battery operates best at temperatures of +10 to +30°C (+50 to +86°F). Recharging should only be performed within this temperature range.
