EL-GFX-2
BAT 3V6 ½AA
FEATURES
• Rugged and robust, IP67 construction
• -30 to +80°C and 0 to 100% RH measurement ranges
• Logging rates between 10 seconds and 12 hours
• Stores over 250,000 readings
• On screen menu and graphing to start, stop, review and restart the logger in the field
• Micro USB interface for PC based set-up and data download
• Immediate, delayed, push-button or temperature/RH triggered start mode
• User-programmable alarm thresholds
• Graphic LCD shows real-time readings, graph and current status
• User set audible alarm
• Highly visible confidence/alarm LEDs
• Supplied with user replaceable ½ AA batteries
The EL-GFX-2 standalone USB data logger measures and stores up to 251,928 temperature and humidity readings over a -30 to +80ºC
(-22 to 176°F) and 0 to 100%RH range at a resolution of 0.1ºC and 0.1%RH. 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.

* This specifies the overall error in the logged readings, for relative humidity measurements between 20 and 80%RH.
** This specifies the overall error in the calculated dew point for relative humidity measurements between 40 and 100%RH at 25°C.
*** At temperatures below -5°C the LCD will exhibit slower response times. The LCD will be disabled at temperatures under -20°C and above 70°C.
† At 25°C and 10 minute logging rate, with no alarm LEDs or sounder and minimal LCD use.
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:
• Logger name
• Measurement parameter (ºC or ºF)
• Logging Rate (customisable between 10 seconds and 12 hours)
• High and low temperature alarms
• Immediate, delayed, push-button or temperature/humidity triggered start mode
• Disable or enable LEDs and sounder with delayed activation
• Display and backlight behaviour after button press
The latest version of the control software may be downloaded free of charge from www.easylogusb.com

BATTERY REPLACEMENT
We recommend that you replace the batteries every 12 months, or prior to logging critical data.
The EL-GFX-2 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-2 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-2 from the PC.
WARNING
Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance with local regulations.
