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.

From the “Main Menu”, use the up/down keys to highlight the appropriate option then push the right
soft key (below the “BACK” button) to select that option.
There are 6 options from the main menu:
VDC Mode: Select to view, analyze, edit or measure DC cell voltages. The DLV50 stores up to 8
strings of 256 readings stored in strings A through H.
HYD Mode: Select to view, analyze or upload additional strings of hydrometer reading from a
DMA35 hydrometer. The DLV50 stores up to 8 strings of 256 readings stored in strings A
through H. Both specific gravity and temperature are stored for each cell.
Export ALL: Select to export all strings of data (both voltage and hydrometer) to USB Flash drive.
Delete ALL: Select to delete all data in all strings (both voltage and hydrometer).
Individual strings can be deleted by selecting the “Delete String” option of the VDC or HYD
mode sub-menu OR by connecting the unit to the Winmeter 5.0 software.
Reset Limits: Select to delete all high and low threshold alarm limits for voltage and hydrometer
readings.
Individual limits for particular strings can also be deleted by selecting the “Limits” option of the
VDC or HYD mode sub-menu OR by connecting the unit to the Winmeter 5.0 software.
Date & Time: Select to view and/or edit the DLV50 date and time setting.
The date and time setting is automatically synced with the PC date and time whenever the
