1.0 Overview
All
DLV40 modes operate
independent
ly
. Erasing the memory in one mode does
NOT
affect readings in the remaining (2) modes
.
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 19.999 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 960 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 (float) 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.

DLV40 Rev: 000.005
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

The DLV40 is designed to measure absolute DC cell voltages between 0.1 VDC and 19.999 VDC. Attempts to measure higher DC voltages will result in an “OVERVOLTAGE!!!” warning.
Cell voltage measurements are taken in a similar fashion to a traditional voltmeter.

In
“Discharge Test”
mode:
- The string capacity of the discharge strings (B through H) is limited to the number of readings in float 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 (7)
For “20x48” or “8x256” modes, please refer to
Section 6.0 to for the Float Test Procedure(s).
For “Discharge Test” mode, please refer to
Section 5.0 to for the Discharge Test Procedure.
3.1 Over Voltage Indication (ALL Modes)
The DLV40 provides both an audio and visual indication if the probes are connected to an excessive input voltage (Vin < -19.999 VDC or Vin > +19.999 VDC) The unit will beep continuously and display:
This warning is removed as soon as the probes are disconnected from the high voltage source.

4.0 Power Saving Features
Note:
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 cancel the auto-off feature.
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.
4.2 Low Battery Indication
Auto-off (10)
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 Voltage
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:
