The OM-EL-USB-5 standalone data
logger can record events (detecting
an input and storing the time and
date of occurrence), 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 in a time period, without
any individual event time or date
information). Up to 32,510 events
or 32,510 state changes can
be recorded.

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 (dry) contacts. In this
case instead of measuring an
external voltage, the data logger
applies a voltage across the screw
terminals and detects when the
input closes (e.g., 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 data logger is supplied
complete with Windows 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. The red LED can be set up to
flash every time an event occurs.

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 included Windows control
software. Easy to install and use,
the control software runs under
Windows®2000, XP, Vista and
7 (32-bit and 64-bit).

The software is used to set-up the
data logger as well as download,
graph and export data to Excel.
The software allows the following
parameters to be configured: logger
name, recording mode (events,
state changes or count events),
triggering on rising of falling edges,
voltage or volt free (dry) contact
triggering, input voltage range, flash
red LED on event/state change,
time period for event counting
(i.e. count the number of events
every 10 s). The maximum number
of events per time period is limited
to 65,000.
