1.0 Overview
The DLV50 data logging voltmeters have been designed specifically for the battery test industry.
The DLV50 is designed to:
• Measure and automatically record DC cell voltages between 0.1 VDC and 19.999 VDC (inclusive)
• Upload and analyze hydrometer data (specific gravity & temperature) from DMA35
hydrometers
The DLV50 is capable of operating in (2) distinct measuring modes:
(i) VDC Mode: The DLV50 can measure and store up to 2048 readings of cell voltages between
0.1 VDC and 19.999 VDC (inclusive). These readings are stored in 8 separate data strings of
256 readings, denoted A through H. The date and time of the last reading in each string is
also recorded.
(ii) HYD Mode: The DLV50 can receive and and store up to 2048 readings of specific gravity and
temperature from a DMA35 digital hydrometer. These readings are stored in 8 separate
data strings of 256 readings, denoted A through H. The date and time of the last reading in
each string is also recorded.
All stored readings can be downloaded via Winmeter 5.0 software to generate detailed test reports
including statistical and graphical analysis and then stored into a custom database. This software
communicates with the DLV50 via USB and allows the User to set the time/date, change modes, delete
data string(s) and upgrade the DLV50 firmware via the PC interface. The readings can also be
transferred to a USB flash drive in .bdf (Winmeter) format.
