-35 to +80°C (-31 to +176°F) measurement ranges. 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 supplied software. Relative humidity, temperature and dew point (the temperature at which water
vapour present in the air begins to condense) data can then be graphed, printed and exported to other applications. The high contrast LCD
can show a variety of temperature and humidity information. At the touch of a button, the user can cycle between the current temperature
and humidity, along with the maximum and minimum stored values for temperature and humidity. The data logger is supplied complete with
a long-life lithium battery, which can typically allow logging for up to 1 year.
* This speciÀ es the overall error in the logged readings for relative humidity measurements between 20 and 80%RH. ** This speciÀ es the overall error in the calculated dew point for relative humidity measurements between 40 and 100%RH at 25°C. *** At temperatures below -20°C (-4°F) the LCD will exhibit slower response times of approximately 10 seconds. † Depending on sample rate, ambient temperature and use of LCD.

Lascar’s EasyLog USB control software is supplied free of charge with each data logger. Easy to install and use, the control software runs
under Windows 2000, XP (Home and Professional Editions) & Vista (32-bit). The software is used to set-up the data logger as well as
download, graph and export data to Excel.
The software allows the following parameters to be conÀ gured:
• Logging rate (10s, 1m, 5m, 30m, 1hr, 6hr, 12hr)
• Immediate, delayed and push-to-start logging
• Display off, on for 30 seconds after button
• Data rollover (allows unlimited logging per ods
by overwriting the oldest data when the memory

The EL-USB-2-LCD features a high contrast LCD and two bi-colour LEDs. The LCD shows logged temperature and humidity values using seven
segment numbers, along with annunciators. The LCD can also show information regarding the logging status.
The LCD shows six different recorded readings, which can be cycled through using the built-in push button. The most recent logged value,
maximum logged value and minimum logged value can be displayed separately for humidity and temperature. In addition, logging and alarm
status is shown using two high intensity LEDs.

EL-USB-2-LCD features 2 bi-colour LEDs; one LED represents temperature measurement, the other represents RH. 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 logging, and 10 seconds later you will see the status of the RH logging, and so on.
The data logger is not currently logging, but is primed to start at a later date and time (delayed start).
The data logger is currently logging. No alarm on the channel.
The data logger is currently logging. Low alarm on the channel.
The data logger is currently logging. High alarm on the channel.
The data logger is full and has stopped logging. No alarm on the channel.
The data logger is full and has stopped logging. Alarm (high, low or both).
The data logger is stopped, the battery is empty or there is no battery À tted.

We recommend that you replace the battery every 12 months, or prior to logging critical data.
The EL-USB-2-LCD does not lose its stored readings when the battery is discharged or when the battery is replaced; however, the data logging
process will be stopped and cannot be re-started until the battery has been replaced and the logged data has been downloaded to a PC.
Only use 3.6V 1/2AA lithium batteries. Check with your supplier that the battery you are ordering is ‘press À t’ and is not À tted with solder tags.
Before replacing the battery, remove the EL-USB-2 from the PC.
Leaving the EL-USB-2 plugged into the USB port for longer than necessary will cause some of the battery capacity to be lost.
Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance with local regulations.

Exposure of the internal sensor to chemical vapours such as those produced by some plastics and foamed materials may interfere with the
internal sensor and cause inaccurate readings to be logged. In a clean environment, this will slowly rectify itself; therefore ensure that the
logger is used in a ventilated area, i.e. air exchange is allowed.
Exposure to extreme conditions or chemical vapours will require the following reconditioning procedure to bring the internal sensor back to
calibration state. 80°C (176°F) at <5%RH for 36h (baking) followed by 20-30°C (70-90°F) at >74% RH for 48h (re-hydration).
High levels of pollutants may cause permanent damage to the internal sensor.
Each EL-USB data logger features the direct-to-USB connection and easy-to-use functionality that the range is known for. The range comprises 14 data loggers as detailed in the following table:
-200 to +1350ºC (-328 to +2462ºF) (K-type)
-200 to +1190ºC (-328 to +2174ºF) (J-type)

Cultural Details: Rudbeckia There are two classes of Rudbeckia, or ‘Black-eyed Susan’ – annual bedding types and and perennial border varieties, which will be dealt with separately here. We also include the Purple Coneflower, Echinacea purpurea, as a perennial type. ANNUAL VARIETIES Annual Rudbeckias make excellent bedding plants, particularly later in the year, with their
