Add another useful feature to the Models 931A and 930A with the 16 MB
Internal Data Memory option (order number 931Aopt01 and 930Aopt01). The 16
megabytes of storage space can turn the Models 931A and 930A into stand alone
Trend Monitors. The characteristic flexibility of the Model 931A Power System
Analyzer and the Model 930A Three Phase Power Analyzer is incorporated into
the 16 MB Internal Data Memory options allowing for custom and user friendly
configuration.
When equipped with the Extended Memory option, the 931A and 930A can be
configured to log data at a set interval, on a valid timer trigger (Model 931A
only), when the front panel log key is pressed or via the RS-232 LOG command.
Two different types of data sets are available for storage, normal and custom.
Normal data sets include four data modes:
-
Standard data, Narrow-Band and Wide-Band parameters for Channels 1 and 2
along with Timer (Model 931A only) and Transducer (Model 931A only)
parameters (153 bytes)
-
Harmonic data, adds the harmonic information from Channels 1 and 2 to
the standard data record (945 bytes)
-
Waveform data, includes standard data, harmonic data, plus the waveform
records for Channel 1 and 2 (1,425 bytes)
-
Three-phase data, the three-phase measurement data for the selected
three-phase display mode (366 bytes)
The Custom data set allows the user to select any combination of the thirty
available individual parameters to log. Record size is dependent on the
selected parameters.
The logged data can be reviewed from the front panel of the Models 931A and
930A or downloaded via the RS-232 port to a computer. Exported data can be
easily incorporated into a spreadsheet or word processor for inclusion into
reports. The PowerCSV Application Software is a useful tool to transfer the
data stored in the internal memory to a computer. |
