EL-USB-5

Counter, Event and State

USB Data Logger

FEATURES

• Functions as an event logger, state change logger and event counter

• Logging rate of up to four times per second for events, two times per

• Stores up to 32,510 readings in event mode

• Stores up to 32,510 readings in state change mode

• Stores up to 32,510 timed intervals in event counter mode

• Accepts input voltages of up to 24V

• Volt free contacts option (normally open contact only)

• Rising and falling edge triggering

• LED flash on event / state change

• Connection via two screw terminals

• USB Interface for set-up and data download

• Supplied with replaceable internal lithium battery, Windows

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 flashing red and green LEDs, with an option to flash the red LED every

time an event occurs.

* 10 milliseconds can only be achieved with the LEDs disabled. If the LEDs are enabled, the time between the event counts is reduced to 50 milliseconds

... We recommend that you replace the battery every 12 months, or prior to logging critical data. The EL-USB-5 does not lose its stored readings when the battery is discharged or when the battery is replaced; however, the data logging process will be stopped and cannot be re-started until the battery has been replaced and the logged data has been downloaded to PC. ...
