1.0 Overview
The DLV40 data logging voltmeters have been designed specifically for the battery test industry. The
DLV40 is designed to measure and automatically record DC cell voltages between 0.1 VDC and 1 .
VDC (inclusive). It has a built in real time clock and calendar which allows for date and time stamping of
readings. The stored readings can then be transferred to a PC via a standard USB connection and the
companion Winmeter 5.0 Battery Analysis Software.
The DLV40 is capable of operating in (3) distinct measuring modes:
(i) “8 by 256” Mode: The DLV40 can measure and store up to 2048 readings of cell voltage.
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) “20 by 48” Mode: The DLV40 can measure and store up to 60 readings of cell voltage.
These readings are stored in 20 separate data strings of 48 readings, denoted A through T.
The date and time of the last reading in each string is also recorded.
(iii) “Discharge Test” Mode: The DLV40 can measure and store up to 2048 readings of cell
voltage. These readings are stored in 8 separate data strings of 256 readings, denoted A
through H.
Readings in String A are reserved for the initial (f oat) voltage of the cell and are NOT time
stamped.
Readings in Strings “B” through “H” are reserved for cell voltages during the discharge (or
charge) test with each reading being time stamped to the nearest second from the start of
the discharge test. The date and time of the last reading 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 DLV40 via USB and allows the User to set the time/date, change modes, delete
data string(s) and upgrade the DLV40 firmware via PC interface.
All
DLV40 modes operate
independent
y
. Erasing the memory in one mode does
NOT
affect readings in the remaining (2) modes
.

2.0 Menu System
The DLV40 uses a simple two tier menu system. The “Main Menu” and (3) sub-menus, one for each
measurement mode (“8 by 256”, “20 by 48” and “Discharge Test”).
2.1 Main Menu
“MENU” Button:
When the DLV40 is in one of the measurement modes, push the MENU button once to enter the
appropriate sub-menu, push the MENU button a second time to enter the Main Menu.
When the DLV40 is in the Main Menu, push once to cancel the current selection.
“ENTER” Button:
Push the ENTER button to accept the current selection.
“UP” and “DOWN” Buttons:
In Main or sub-menu modes push to change the current selection.
In any of the (3) measurement modes push once to increment/decrement the cell pointer, push and
ho d to scroll through the readings.

3.0 Taking a Ce Vo tage Measurement (ALL Modes)
Cell voltage measurements are taken in a similar fashion to a traditional voltmeter.
(i) Turn the DLV40 ON.
(ii) Select the required measurement mode (“20x48”, “8x256” or “Discharge”).
(Please refer to section X.X for Mode selection for more information)
(iii) Select required string.
For “20x48” or “8x256” mode:
- If old data is present, de ete string(s) data as required.
For “Discharge Test” mode:
If an old Discharge Test data is present, de ete the existing Discharge Test data.
The DLV40 is designed to measure absolute DC cell voltages between 0.1 VDC and 1 . VDC.
Attempts to measure higher DC voltages will result in an “OVERVOLTAGE!!!” warning.
