Battery Voltage Recorder BVR22 is a handheld device intended for measuring string voltage, single cell voltage, inter-cell connection voltage, ambient temperature, and cell temperature. Additionally, it enables simultaneous measurement of string voltage and DC current and helps the user to determine the capacity of the battery.

BVR22 can be used for measuring voltage and temperature parameters while battery is either connected or disconnected from the network. BVR22 measures and records voltage and temperature data in its internal memory, with an ability of storing measurements for up to 200 different strings. Measured parameters are displayed on the 2.8 inch color display.

Due to its ability to cover a wide voltage measurement range of up to 600 V DC, large battery banks as well as single batteries can be tested and supervised with this device. Download of collected data to an external computer is available via USB and Bluetooth communication. Detailed analysis and trending of battery banks and single batteries’ state of health is enabled by using DV-B Win software application set.

The DV-B Win software is included in the price, and all its updates are free of charge. Using the DV-B Win software a test can be performed and monitored from a PC, and the results can be saved directly to a PC. Communication between the BLU and a PC is achieved through a USB cable. Using the DV-B Win, the results can be arranged and printed for a report in selectable formats as XLS, PDF, Word, or RTF. Also, a possibility of importing other types of data formats (jpg, png, doc) into standardized DV-B Win report is provided, as well as exporting the numerical and graphical results from the DV-B Win into a customizable report. Additionally, the software provides a possibility of setting extra parameters (cell voltage, string voltage, capacity and time) for alarming and terminating the test.
