Description

The EL-USB-3 data loggers are a 0-30V data logger with an internal memory for up to 32,510 readings. The data logger includes a pair of screw terminals to connect the DC voltage signal to the logger. A set of measurement leads terminated in crocodile clips are supplied with the kit to allow for a quick easy connection method. The terminals are fitted into the protective cap, which covers the USB port for configuration and downloading the collected data. The internal battery is a replaceable long-life Lithium battery, which can provide up to 3 years operation (25°C @ 2 second logging).

This standalone data logger can be used with DC voltages in the range of 0-30V. The EL-USB-3 also features two LEDs: a green/red LED to indicate logging and alarm status. In normal operation the green LED will flash, but will change to red if an alarm condition has been triggered and can be set to remain on until cleared by the user. This feature is useful to highlight the presence of an alarm condition in the logged data.

EasyLog USB Software

The EasyLog USB control software is available as a free download from here. The software is easy to install and use, plus is compatible with 32-bit and 64-bit versions of Windows 7, 8 and 10. The software is used to set up the logger, alarms, download, graph and annotate data or export in Excel, PDF and jpeg formats. It is also 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.

The software allows the following parameters to be configured:

• Logger name
• Logging rate (user selectable between 1 seconds and 12 hours)
• High and low alarms
• Immediate and delayed logging start
