System Overview:
Battery Voltage Recorder series of instruments are specially designed for measuring battery voltage and temperature values.
IEEE standards for stationary batteries applications stipulate measuring voltages of both single batteries as well as total battery system voltages periodically. These measurements are recommended to be taken during batteries’ float operating modes and periodical battery capacity testing.
Additional feature for all three models is DC current measurement using current clamps.
For different customer’s requirements, three models of Battery Voltage Recorder series are available.
All models can transfer measured data to DV-B Win for an extensive analysis of battery’s condition and state of health.
DV-B Win Software:
Using the DV-B Win software package all results can be presented in several forms. Single battery voltages can be shown in a table, scan graph, as well as a line view.
To perform detailed comparisons and analysis of measured data, a user defined limits for battery, and string voltage as well as temperature, are displayed in the scan graph view along with measured results.
A test report of collected data can be generated and user customized for a comprehensive battery state of health assessment.
Numerical and graphical results may be exported from DV-B Win in selectable formats such as Excel spreadsheet, PDF, Word or Rich Text Format.
Additionally, importing other types of data formats (.jpeg, .png, .doc) into standardized DV-B Win report is provided as well.
DV-B Win software provides an alarm notification when detecting cells with voltage levels lower or higher than defined thresholds.
