EL-USB-2 Temperature, Humidity and Dew Point Data Logger -35 to +80C (-31 to +176F) and 0 to 100%RH measurement range Stores over 16,000 readings for both temperature and humidity EasyLog software available as a free download Logging rates between 10 seconds and 12 hours Immediate and delayed logging start User-programmable alarm thresholds for both temperature and humidity Status indication via red/green LEDs Environmental protection to IP67 This standalone data logger measures and stores over 16,000 temperature and humidity readings from -35 to +80C (-31 to +176F) and 0 to 100%RH range at a resolution of 0.5C (1F) and 0.5%RH. 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, including calculated dew point, can then be graphed, printed and exported to other applications for detailed analysis. The data logger is supplied with a lithium metal baertt y, giving up to three years logging life. The logger is protected against ingress from water and dust to IP67 standard when the cap is fitted.

Issue 14 08/2016 N.R Page 1 of 4EL-USB-2 Temperature, Humidity and Dew Point Data Logger 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 & 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.easylogusb.com LED STATUS INDICATION The EL-USB-2 features two green/red LEDs, one to represent temperature measurement and the other to represent humidity measurement. Each is clearly marked on the logger. To save power, the status indication alternates between the two channels every 10 seconds. First you will see the status of the temperature channel and 10 seconds later you will see the status of the RH channel and so on. 10 seconds later RH% C (F) RH% C (F) In normal operation the green LED will flash, but will change to red if an alarm condition has been triggered. 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. Green double flash The data logger is not currently logging, but is primed to start at a later date and time (delayed start) Green single flash The data logger is currently logging. No alarm on the channel Red single flash The data logger is currently logging. Low alarm on the channel Red double flash The data logger is currently logging. High alarm on the channel Green triple flash The data logger is full and has stopped logging. No alarm on the channel Red triple flash The data logger is full and has stopped logging. Alarm (high, low or both) on the channel No LEDs flash The data logger is stopped, the baertt y is empty or there is no baertt y Dual Red flash (every 60 seconds) The data logger baertt y is running low as its voltage has dropped below 2.9V www.lascarelectronics.com Issue 14 08/2016 N.R Page 2 of 4
