EL-USB-1 Temperature Data Logger -35 to +80C (-31 to +176F) measurement range Stores over 16,000 readings EasyLog software available as a free download Logging rates between 10 seconds and 12 hours Immediate and delayed logging start User-programmable alarm thresholds Status indication via red/green and amber LEDs Environmental protection to IP67 This standalone data logger measures and stores more than 16,000 temperature readings over a -35 to +80C (-31 to +176F) range with a resolution of 0.5C (1F). The user can easily set up the logger and view downloaded data by plugging the data logger into a PCs 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 supplied with a lithium metal baertt y which gives three years logging life. The logger is protected against ingress from water and dust to IP67 standard when the cap is fitted. EL-WIN-USB Lascars 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 Measurement parameter (C or F) Logging rate (user selectable between 10 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 SPECIFICATIONS ACCESSORIES BAT 3V6 1/2AA Replacement Measurement range -35 to +80C (-31 to +176F) baertt y Internal resolution 0.5C (1F) EL-USB-CASE Protective metal Accuracy (overall error) +/- 0.5C typical (see graph on page 2) case Logging rate User selectable between 10 seconds & 12 hours EL-DataPad Handheld data logger programmer Operating temperature range -35 to +80C (-31 to +176F) & collector Baertt y Life 3 years (at 25C and 1 minute logging rate) Readings 16,382 INCLUDED IN THE BOX Dimensions 99 x 25 x 23mm (3.89 x 0.98 x 0.90) BAT 3V6 1/2AA Baertt y EL-USB WALL BRACKET Mounting Bracket CALIBRATION CERTIFICATES NOW AVAILABLE Lascar now offers a Traceable Calibration Certificate Service on Temperature Data Loggers.

Issue 16 02/2017 Page 1 of 2EL-USB-1 Temperature Data Logger LED STATUS INDICATION Green double flash The data logger is not currently logging, but is primed to start at a later date The EL-USB-1 features two LEDs: a green/ and time (delayed start) red LED to indicate logging and alarm Green single flash status, and an amber LED to indicate a The data logger is currently logging. No alarm possible problem. Green and Amber single flash The data logger is full and has stopped logging. No alarm In normal operation the green LED will Red single flash flash, but will change to red if an alarm The data logger is currently logging. Low alarm condition has been triggered. Using Red and Amber single flash EL-WIN-USB it is possible to set the alarm The data logger is full and has stopped logging. Low alarm to remain active even if the reading has Red double flash returned to normal, in which case the The data logger is currently logging. High alarm alarm LED will continue to flash red. Red and Amber double flash This Hold feature in the software The data logger is full and has stopped logging. High alarm ensures the user is notified that at some Amber single flash point an alarm level has been exceeded, The baertt y is running low. Data logging will continue until the baertt y voltage without needing to download the data. drops below 2.8V No LEDs flash The data logger is stopped, the baertt y is empty or there is no baertt y BATTERY INFORMATION Replacement We recommend that you replace the baertt y annually, or prior to logging critical data. Only use 3.6V AA lithium metal baeriett s. The data logger does not lose its stored readings when the baertt y is discharged or replaced however, the data logging process will stop and will not resume until the baertt y is replaced and the logger restarted by EL-WIN-USB or an EL-DataPad. Before replacing the baertt y, 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 the baertt y capacity to be lost. Passivation If left unused for extended periods of time lithium metal baeries, tt including those used in the EasyLog range of data loggers, naturally form a non-conductive internal layer preventing them from self-discharge and eectivff ely increasing their shelf life. When first installed in the data logger, this may cause a momentary drop in the baertt y voltage (the Transient Minimum Voltage) as the internal layer is broken down, resulting in the data logger resetting. Inserting the baeries tt in the data logger and leaving it connected to a PC for about 30 seconds will remove this layer. After this, remove and re-install the baeries tt to reset the data logger. Overall baertt y life will not be aectff ed. WARNING Handle lithium metal baeries ctt arefully, observe warnings on baertt y casing. Dispose of in accordance with local regulations.
