ECORDING
To begin a new recording, slide the
access door closed. The LED indicator
will begin to flash for 10 seconds.
During this period the recording can
be canceled without losing the data
previously recorded. When the LED
indicator stops flashing, a new
recording has begun and any previous
data has been erased. The OM-DLAC
recording function can be “locked” on
by passing a Ty-Wrap™ or similar restriction through the logger-mounting
opening. This can be used to prevent accidental or intentional disruptions of an
AC current recording.
The LED will flash every 5 seconds to indicate operation. A bright flash of the
LED is used to indicate that the loop current has been sampled and recorded. A
dim flash is used to indicate that the OM-DLAC is operating properly and the AC
Current has not been sampled or recorded. The LED indicator will continue to
flash until the user stops the recording or the memory has reached its maximum
capacity of 16,000 samples.
NOTE:
If the battery is exhausted during a recording, the OM-DLAC will
automatically terminate the recording and save any data recorded up to that
point. The LED will stop flashing and the OM-DLAC will not allow a new re-
cording to be started until the battery has been replaced. Recorded data
can be retrieved regardless of the condition of the battery.

Slide the access door open (If
locked, remove the restriction
device first.) The LED indicator will
stop flashing. The recorded data
can now be retrieved using the
supplied Windows™ compatible
software and PC interface, or the
AC Current recording can be
plotted on a circular chart using the
optional OM-DP3 Data Plotter.
NOTE: Do not close the door until a new recording is desired!
It is important
to leave the door open until you want to start a new recording. Starting a new
recording now will erase the previous recording. To prevent accidental erasing
of recordings, the access door of the OM-DLAC can be “locked” open by pass-
ing a Ty-Wrap™ or similar restriction through the lock opening. The AC Current
recording will remain in the OM-DLAC until a new recording is started. The re-
cordings may be retrieved as many times as required or the battery can be re-
