The OM-DVCV is a self-contained, precision instrument for recording AC current and AC voltage.
The OM-DVCV can record voltage up to 600 Vac and current up to 300 Aac. The OM-DVCV records true RMS AC current and AC voltage. It measures RMS signals up to the 21st harmonic at 60 Hz. The OM-DVCV can store up to 21,672 points when recording both voltage and current. It can store up to 43,344 samples when recording only voltage or only current.
The OM-DVCV features a display that allows the user to see measured current, voltage and power (in Watts). In addition, the unit graphs the current and voltage that has been logged during the current logging session. A summary screen shows information about the logging session, such as the logging rate, the number of samples recorded, the length of the recording and the amount of time left for recording.
Easy-to-use Windows software is included with the OM-DVCV. The software is a full-featured program that allows you to set-up all data logger functions including sampling rate, logging duration, start mode, logging mode, and high and low alarm values. Once data has been logged, the program then allows you to download data from the logger, plot the data and export the data to an ASCII text or Excel® file format for further analysis.

Functional and easy to useThis is a compact unit that can be placed inside most industrial enclosures and out of site for data logging purposes. We collected data over a seven day period and was very satisfied with the results. The set is very intuitive and the data can be exported to a .XLS file and manipulated into several types of reports.

Great Value!I have used this for logging equipment loads for 24hrs a day for a full week now. It is simple to set up and activate. It is a really nice unit for the relatively inexpensive cost. The output of data is easy to import into Excel for manipulation and plotting. the unit's internal plotting is a decent instant visual if you are mainly observing trends. I would buy this again.

Great valueWe are measuring the site load of an existing off-grid installation, and the unit has been ideal. Very easy to use out of the box. The only issue is that the it takes a little fiddling to get the USB driver to work, but that is minor.

Nice UnitNice little unit to measure both current & voltage. I used this device to monitor the cycle time of an air compressor motor. I was able to set it to sample the voltage every 30 seconds over a two week period. The only negatives are the size of the included alligator clips which were too large for my application. Also, you need to visit the Omega website to download the correct software. It is available for various computer operating systems which were not included in the package.

Almost perfeclittle loggerThis logger has the features and software that is easy to use and the loggers are a easy to set up. One thing it needs is more memory for longer duration. I'm logging emergency branch circuits that need 2-10 second intervals for 30 days for engineering purposes. This unit does not have the capacity for that many points of data. Now I am having to swap loggers ever 48 hours for data and open the electrical cabinet every two days. This increases my risk of arc flash exposure etc...It would be nice if the spec sheet online listed the data point memory so I could determine if the logger was suitable for my application.
