Datasheet
This standalone 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).
Up to 32,510 events or state changes can be recorded and up to 32,510 timed intervals in event counter mode (with 65,536 events in each
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).
Fast logging rates allow event capturing at speeds of up to two times per second and state changes at speeds of up to four times per second.
Event counting can operate at speeds of up to 100 times per second (when the LEDs are turned off). The user can easily set up the logger,
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, Vista & 7. Data can then be graphed, printed and exported to other applications.
The data logger is supplied complete with software, measurement leads terminated with crocodile clips and a long-life lithium battery which
allows logging for up to 1 year. Functionality of the unit is indicated by ashing red and green LEDs, with an option to ash the red LED every
time an event occurs.
