4-20mA Current Loop Data Logger • 4-20mA d.c. current loop measurement range • Stores over 32,000 readings • Logging rates between 1 second and 12 hours • Connection via two screw terminals • Immediate and delayed logging start • User-programmable alarm thresholds • Status indication via red and green LEDs • EasyLog software available as a free download. This stand-alone data logger measures and stores over 32,000 current loop readings over a 4-20mA d.c. range at a resolution of 0.05mA d.c. The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the available free downloadable EasyLog software. Data can then be graphed, printed and exported to other applications. The data logger is delivered complete with a lithium metal battery, which gives three year’s logging life. The data logger is also issued with a 4-20mA cap featuring a pair of screw terminals and measurement leads terminating in crocodile clips. EASYLOG SOFTWARE Lascar’s EasyLog control software is available as a free download from www.easylogusb.com. Easy to install and use, the control software is compatible with 32-bit and 64-bit versions of Windows 7, 8 and 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 • Logging rate (user selectable between 1 seconds and 12 hours) • High and low alarms • Immediate and delayed logging start Download the latest version of the software free of charge from www.lascarelectronics.com/software/easylog-usb Measurement range Replacement battery Internal resolution Accuracy (overall error) Input impedance Logging rate User selectable between 1 second & 12 hours Operating temperature range Battery Life 3 years (at 25°C and 2 second logging rate) EL-USB WALL BRACKET Mounting Bracket Measurement Leads

4-20mA Current Loop Data Logger LED STATUS INDICATION The EL-USB-4 features two LEDs: a green/red LED to indicate logging and alarm status. In normal operation the green LED will flash, but will change to red if an alarm condition has been triggered. Using EasyLog software 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. Green single flash (Every...

4-20mA Current Loop Data Logger BATTERY INFORMATION Replacement We recommend that you replace the battery annually, or prior to logging critical data. Only use 3.6V ½AA lithium metal batteries. The data logger does not lose its stored readings when the battery is discharged or replaced; however, the data logging process will stop and will not resume until the battery is replaced and the logger restarted by EasyLog software. Before replacing the battery, remove the data logger from the PC. Please note that leaving the data logger plugged into the USB port for extended periods will cause some of...
