  OM-DLAV DATA LOGGER INSTRUCTIONS

The OMEGA OM-DLAV Data Logger is a self-contained precision instrument for

recording AC voltage. The OM-DLAV can store up to 16,000 measurements for

each recording. The recordings can be read using the supplied PC interface or

the optional OM-DP3 Data Plotter.

The Windows™ compatible software allows the user to set the OM-DLAV for a
recording session, read the recorded data in text or graphical format, and to
store the recorded data for future reference or analysis. Applications include
monitoring of compressor and fan run cycles, new installation tests, trouble
shooting intermittent problems, monitoring line voltage, etc. Refer to the follow-
ing instructions for explanations of how to record and how to retrieve AC voltage
recordings.

The OM-DLAV recording interval or, sampling rate, is the time between each

voltage measurement that is saved in the logger’s memory. This interval is set

from the PC interface program (supplied) or from the optional OM-DP3 Data

Plotter. This interval can be set from 5 seconds to 60 minutes. A user message

of up to 20 characters can also be stored in the OM-DLAV. This message can be
