Thermocouple Data Logger with LCD and USB Interface

This standalone data logger measures and stores up to 32,510 temperature readings from either a J, K or T type thermocouple . A thermocouple is attached via the thermocouple socket at the base of the unit. The user can easily set up the thermocouple type, logging rate, start-time, logging mode, and download the stored data by plugging the data logger into a PC’s USB port and running the purpose designed software under Windows 2000, XP or Vista. Data can then be graphed, printed and exported to other applications. The data logger is supplied complete with a long-life lithium battery, which will last for approximately 6 months.

Your Thermocouple

The probe supplied with your EL-USB-TC-LCD is a K-type thermocouple designed to measure temperatures from 0 to 400ºC (32 to 752ºF). The EL-USB-TC is designed to work with J, K and T-type thermocouples with a standard mini thermocouple connector; this makes your data logger compatible with a wide range of available thermocouples. Your application will determine which probe is most suitable based on temperature range, accuracy, form and price. For information on a wide variety of alternative thermocouples, please contact the following companies:

Display and Status Functions

The EL-USB-TC-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 annunicators. 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 seperately for humidity and temperature. In addition, logging and alarm status is shown using two high intensity LEDs.

LED Flashing Modes

EL-USB-TC-LCD features two LEDs, that indicate the logging, battery and alarm status:

• The first LED flashes red to indicate that the EL-USB-TC is in an alarm condition. It will flash when the logged temperature has exceeded a Low or High alarm level.
• The second LED flashes green to indicate that the EL-USB-TC is not in an alarm condition.

Hold is enabled by default, which forces the logger to continue flashing the red LED after an alarm, even when the temperature has returned to normal. This feature ensures that the user is noticed that an alarm level has been exceeded, without the need to download the data from the logger.

Hold can be turned off via the control software. The red LED will then only flash whilst the logger is in an alarm condition. When the temperature returns to normal, the green LED will flash.

Additional LED modes are explained below:

* Operating temperature applies to the data logger module only. Please consult the probe manufacturer for operating temperature of thermocouple.
** Quoted accuracy is for the data logger only and excludes the thermocouple probe. Thermocouple error should also be taken into consideration.
*** Depending on sample rate, ambient temperature and use of LCD.

EasyLog Software

The core of Lascar's data logging solution is the free software supplied with each data logger. Using a wizard format to guide the user through setup of the data logger and subsequent download of collected data, the software puts the 'easy' into EasyLog.

Features

• Collects and stores data from at least 500 data loggers
• View downloaded data with general trend and summary screens
• Allows full or quick set-up of compatible EasyLog USB data loggers
• Touch screen interface for navigation of menus
• 2.8” TFT display
• Stored data can be transferred to a PC/Mac via micro USB cable
• Use Lascar’s EasyLog USB software on a PC to graph data and export to Excel
• Integral rechargeable lithium battery provides up to 8 hours use (nominal)

The EL-DataPad allows users of Lascar’s EL-USB data loggers to configure their units and download data and view logging results on-thespot rather than removing the logger from the environment being measured and taking it to their PC. This allows continual logging with shorter breaks in data collection, less travel for the user, on-site data collection in graph, legend and summary format and the ability for users to reconfigure loggers in ‘the field’.

The logger is connected to the EL-DataPad via a standard USB port at the top of the viewer. Once connected, the user is guided through a simple touchscreen menu with options to Set-Up Logger, Stop Logger & Download and View Data. On-screen instructions follow the same structure as Lascar’s EL-USB-WIN software for PC currently provided with each data logger.

Data from up to 100 loggers can be viewed on the EL-DataPad, with data from a further 400 units stored on the unit at any one time. Data can be transferred to a PC or Mac using a micro USB cable supplied with the unit. Once uploaded, data is saved in comma separated variable (csv) format, making it suitable for import into spreadsheet packages such as Microsoft Excel or graphed on a PC using Lascar’s EL-WIN-USB software .

The EL-DataPad is compatible with the following EL-USB data loggers: EL-USB-1, EL-USB-1-LCD, EL-USB-1-PRO, EL-USB-2, EL-USB-2+, EL-USB-2-LCD, EL-USB-2-LCD+, EL-USB-TC, EL-USB-TC-LCD, EL-USB-LITE.
