  OM-DLAC DATA LOGGER INSTRUCTIONS

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

recording AC Current using a clamp on probe. The OM-DLAC 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-DLAC 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, etc. Refer to the following instructions for expla-
nations of how to record and how to retrieve AC Current recordings.

The OM-DLAC recording interval or sampling rate is the time between each cur-
rent 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-DLAC. This message can be used to

poses. Use the example below to set a OM-DLAC logger.
