EL-GFX-1

## **EL-GFX-1** Temperature Data Logger with Graphic Screen 

-   -30 to +80°C (-22 to +176°F) measurement range 

-   Stores over 250,000 readings 

- EasyLog software available as a free download 

-   Logging rates between 10 seconds and 1 hour 

- On-screen graphing and menu options to start, stop, 

- review and restart the logger in the field 

- Immediate, delayed, push button or level triggered start mode 

-   User-programmable audible alarm thresholds with highly visible confidence/alarm LEDs 

- Environmental protection to IP67 

This stand-alone data logger measures and stores over 250,000 temperature readings over a -30 to +80°C (-22 to +176°F) range at a resolution of 0.1°C (0.2°F). 

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 free EasyLog software. Data can then be graphed, printed and exported to other applications for detailed analysis. 

The data logger features a high contrast dot-matrix LCD and three buttons to navigate through an on-screen menu. This menu provides the user with access to real-time trend analysis, data summaries and the ability to start, stop and restart the data logger without the need to connect the data logger to the host-PC. Users can reset the maximum / minimum reading using the on-screen menu. This introduces an ‘event marker’ into the data which can later be viewed in the graphing software (‘Mark Events’ option) and the data file after download. 

The data logger is supplied complete with two lithium metal batteries, which can typically allow logging for up to 1 year and is protected against moisture to IP67 when the battery case is securely fitted. Can be powered from USB.

## BATTERY INFORMATION 

## **Replacement** 

We recommend that you replace the battery every year, or prior to logging critical data. Only use 3.6V ½AA lithium batteries. The data logger does not lose its stored readings when the battery is discharged or replaced; however, the data logging process will stop and will not resume until the battery is replaced. The logger may need to be restarted by EasyLog software. 

Before replacing the battery, remove the data logger from the PC. 

## **Passivation** 

If left unused for extended periods of time, lithium batteries, including those used in the EasyLog range of data loggers naturally form a non-conductive internal layer, preventing them from self-discharge and effectively increasing their shelf life. When first installed in the data logger, this may cause a momentary drop in the battery voltage (the Transient Minimum Voltage) as the internal layer is broken down, resulting in the data logger resetting. Inserting the batteries 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 batteries to reset the data logger. Overall battery life will not be affected. 

## WARNING 

Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance with local regulations.
