The EL-GFX-1 standalone USB data logger measures and stores up to 251,928 temperature readings over a -30 to +80ºC (22 to +176ºF) range and at a resolution of 0.1ºC. Using the Windows control software (available as a free-download from www.easylogusb.com), users can quickly set up the data logger and view downloaded data by connecting the device to the PC’s USB port using the supplied cable.
The data logger features a high-contrast graphic LCD and three-input buttons. This allows users to start, stop and restart the data logger using on-screen menus. This menu also provides real-time analysis of data either as a data summary (showing highest & lowest readings and alarm conditions) or as a graph that updates as new data is added. Multiple data logging sessions can be stored on the device ready for upload to a PC at a later date.
The data logger’s robust design provides IP-67 waterproof protection and the two replaceable ½AA batteries typically allow logging for up to one year.

EL-WIN-USB (CONTROL SOFTWARE)
Lascar’s Easylog USB control software is available to download from www.easylogusb.com. Easy to install and use, the control software runs under Windows XP, Vista and Windows 7. The software is used to set-up the data logger as well as download, graph and export data to Excel. Each stored logging session is saved as a separate file.
The software allows the following parameters to be configured:
|Menu Button Functions and Led Screen Indication|
|We recommend that you replace the batteries every 12 months, or prior to logging critical data.
The EL-GFX-1 does not lose its stored readings when the batteries are discharged or when the batteries are replaced; however, the data logging process will be stopped. If the batteries are changed within a 2 minute window the EL-GFX-1 will retain its settings (internal clock and logging mode). This will allow logging to be restarted without additional connection to a PC via USB.
Only use 2 x 3.6V ½AA lithium batteries. Do not mix battery types and do not mix new and old batteries. Before replacing the batteries, unplug the EL-GFX-1 from the PC.
Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance with local regulations.
