• Log up to 4 state changes/second or 2 events/second
• Volt free contacts option (normally open contact only)
• Rising and falling edge triggering
• Connection via two screw terminals
• Status indication via red and green LEDs
• EasyLog software available as free download

This stand-alone data logger can record events (detecting an input and storing the time and date), record state changes (similar to an 'event' but also recording when the input reverts back to normal) and count events (count the number of events that happen during a timed interval). Over 1 million events or state changes can be recorded, or over 1 million timed intervals in count per mode (with up to 65,000 counts per interval). Events and state changes can be triggered by either a rising edge (a voltage going from low to high) or falling edge (a voltage going from high to low). It is also possible to use volt free contacts. Instead of measuring an external voltage, the data logger applies a voltage across the screw terminals and detects when the input closes (i.e. a relay or microswitch). The logger can record events at speeds of up to two times per second and state changes at speeds of up to four times per second. In counting modes the logger can operate at speeds of up to 100 counts per second. 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 available free downloadable EasyLog software. Data can then be graphed, printed and exported to other applications. The data logger is supplied complete with a lithium metal battery, which gives up to one year's logging life. The data logger also comes with a set of measurements leads terminated in crocodile clips.
