Lascar EL-SIE-2+ - User Manual

EL-SIE-2+
High Accuracy Temperature and Humidity
USB Data Logger, EasyLog Cloud Compable
Monitor the environment you live and work in with the EasyLog EL-SIE-2+. Conguraon is simple, with no soware to install
on your PC or Mac – just connect the logger with a USB cable, and use your standard web browser to congure the device for
logging. You don’t even need internet access to set up and use the EL-SIE-2+, it really couldn’t be easier.
The logging interval can be set between 10 seconds and 24 hours, with immediate, delayed, triggered or push-to-start logging.
Alarms are fully user congurable, with funconality including cumulave alarms, pre-alarms, a delay before alarm triggering,
and an alarm hold opon, which connues showing the alarm condion even if the reading returns to an acceptable level.
The display shows current, maximum and minimum readings, and three coloured LEDs indicate device status at a glance.
Once logging is complete, re-connect to your computer and use your browser to view, analyse and save your data. You can also
choose to upload your data to an Easy Log Cloud account, making the data accessible online for powerful graphing, analysis and
report generaon.
Typical baery life is over 1 year using standard AAA alkaline baeries, and a wall mounng bracket is supplied with the device.
