To exit theprogram, click on the Exit button on the tool bar.T O S TART A R ECORDINGTo begin a new recording, slide theaccess door closed. The LED indicatorwill begin to flash for 10 seconds.During this period the recording canbe canceled without losing the datapreviously recorded. When the LEDindicator stops flashing, a newrecording has begun and any previousdata has been erased. The OM-DLACrecording function can be “locked” onby 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.T O S TOP A R ECORDINGSlide the access door open (Iflocked, remove the restrictiondevice first.) The LED indicator willstop flashing. The recorded datacan now be retrieved using thesupplied Windows™ compatiblesoftware and PC interface, or theAC Current recording can beplotted on a circular chart using theoptional 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-moved with no effect on the stored data.C ONNECTING THE OM-DLACPlug each lead from the clamp on probe firmly into the OM-DLAC.

Youcan click the plus or minusbutton to make the data loggerreading match with the referencereading that you recorded at thesame time and same place withthe OM-DLAC. Click the OKbutton and the software willmake a new data retrieval basedon your new calibration setting.The new calibration setting will be saved in the OM-DLAC and apply to all future recordings.B ATTERY R EPLACEMENTThe OM-DLAC Data Logger uses a 9-Volt Alkaline battery, which will have an average life of 1 year. The actual life of the battery will depend on a variety of factors such as the temperature the battery is used in, the sampling rate of the logger, and how often the OM-DLAC is used. Extreme temperatures will result in reduced battery life. If the battery is exhausted during a recording, the OM-DLACwill 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 record-ing to be started until the battery has been replaced. Recorded data can be re-trieved regardless of the condition of the battery.When the logger will not be used for an extended period, or when the battery is exhausted, it is strongly recommended to remove the battery to avoid damage to the logger from battery leakage. Use only Alkaline batteries in theOM-DLAC. Substitution of a different battery can result in reduced perform-ance or permanent damage to this instrument.To replace the OM-DLAC’s battery follow the steps below:1.Make sure the logger is not set in the recording position. If so, slide the dooropen. Any information recorded up to this point will not be lost and is auto-matically saved.2.Remove the rear battery cover.3.The battery and battery clip may be extended from the battery compartmentto facilitate replacement.4.Remove the battery from the logger and dispose of properly. To assureproper reset of the logger wait at least one minute before connecting new battery.5.Line up the connector of the new battery and push onto the pins of the bat-tery clip with a firm motion. Do NOT reverse the battery connection, even momentarily, as this can result in loss of data or permanent damage to the logger.6.Place the battery in the battery compartment of the OM-DLAC.7.Replace the battery cover.Once the battery has been replaced it will be necessary to reset the logger’s internal clock. Refer to the section, “Setting the Data Logger” for instructions on how to do this.OM-DLAC S PECIFICATIONS+10°F to +150°F (-12°C to +65°C) Ambient Operating TemperatureRangeStorage Temperature-40°F to +170°F (-40°C to +76°C) Time Accuracy+/- 100ppm @ 75°FCurrent Range0 to 300 Amps AC using suppliedclamp-on probeCurrent Resolution0.1 Amp ACCurrent Accuracy+/- 5%Memory Capacity16,000 Data SamplesSize 2.5˝ x 3.6˝ x 1.1˝Weight0.26 lbs.Power Source9 Volt Alkaline Battery(Not Supplied)Battery Life 1 year (Average use)11OM-DP3 D ATA P LOTTERThe OM-DP3 is an optional accessory instrument that allows the user to retrieve data and program dataloggers in the field without the need of a computer.
