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
.

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.

measurements. When the readings are stab e (within +/- 0.005 VDC) the DLV40
automatically beeps, the back ight f ashes and the reading is he d on the display.
(v) Remove the voltage probes from the cell terminals.
The reading is he d on the display until the probes are removed. After approximately (1)
second the DLV40 stores the reading, adds the reading to the sum of string cell voltages and
increments to the next reading.

3.1 Over Vo tage Indication (ALL Modes)
The DLV40 provides both an audio and visual indication if the probes are connected to an
excessive input voltage (Vin < -1 . VDC or Vin > +1 . VDC)
The unit will beep continuously and display:
This warning is removed as soon as the probes are disconnected from the high voltage source.
In
“Discharge Test”
mode:
- The string capacity of the discharge strings (B through H) is imited to the number of
readings in f oat string (String A).
- Once the last discharge reading is taken, (strings B through H), the DLV40 will automatically
increment to the next string.
- The user then must wait for the required test interval before taking the next set of discharge
cell voltage readings. The required test interval is typically ~Discharge test length divided by

3.2 Recording Over a Previous Measurement (ALL Modes)
To record over a previous measurement:
(i) Use the UP or DOWN buttons to scroll to the required reading location.
(ii) The currently stored reading is shown for approximately (2) seconds then the DLV40
reverts to measurement mode.
(iii) Connect the probes to the appropriate cell and take measurement.

4.0 Power Saving Features
4.1 Auto-Off
After approximately (3) minutes of non-operation, the unit will beep and display an auto-off warning
for 10 seconds. Pressing any button during the 10 seconds will cance the auto-off feature.
4.2 Low Battery Indication
A low battery is indicated by ay a “Low Battery!” prompt.The user can push “ENTER” to disregard but
is recommended that the battery is replaced before the next scheduled use.
4.3 Checking Battery Vo tage
To check the battery voltage at any time:
(i) If not in Main Menu, press the “MENU” button twice to enter the Main Menu:
(ii) Use the “UP” or “DOWN” buttons to select Discharge Test Mode:
Auto-off (10)
Note:
If a “Discharge Test” has been started, the DLV40 will continue to measure the time elapsed
since the discharge test was started.
In ALL modes, when turned ON the DLV40 will automatically start in the previous mode and
“point” to the next reading location.
