1.
Set up the Receiver first.
2.
Turn on the unit. A series of messages flashes across the screen.
3.
The display stops at WAND “Y or N.” If you bar-code, press the “S” button and enter the necessary data for site, cell and
ambient temperature. If you do not bar-code, press the “T” button.
4.
The display stops at ENTER BASELINE “Y or N.” If you want to enter a baseline value, press the “S” button and enter the value
by scrolling to enter 0 to 9 plus the decimal point using the “S” and/or the “T” buttons. Use the <Enter> key to move to the
next character. It will ask for a warning level in percent change from the baseline then a fail level.
5.
The display then stops at SPLIT STRAP “Y or N.” If your test current path is split among a number of straps, press “Y.” Enter the
number of parallel paths and save (scroll through the # with the <Enter> key. Press <Enter> again to confirm). If your test
current path involves only one strap, press “T”.
6.
The display will ask if you wish to SAVE SETTINGS “Y or N”. If no, then it will return to ENTER BASELINE “Y or N”. If you are
satisfied with the entries, press the “S” key.
7.
The display tells you to connect the “CT”, then measure the RIPPLE CURRENT flowing in the battery circuit. To store the ripple
current measurement, pull the trigger.
8.
The display reads CONNECT & POWER TRANSMITTER.
9.
Connect the transmitter to line power and turn on switch, S1.
10. Connect all leads, red to the (+) bus and black to the (-) bus.
For consistent results, make the current source lead connections to the cable, lug or terminal plate that connects to
the battery terminals.
11. Press the “Current On/Off” switch. After a short delay, the Current Ready lamp lights and the LCD displays the magnitude of
current applied across the battery system.
12. The Receiver display will show the total test and ripple currents flowing in the battery circuit. Pull the trigger to save the total
test current measurement.

13. The first line of the display shows 001 and the actual current level in the battery string. If the test current is outside the test
limits, the display shows Lo / Hi. The second line shows TEST NUMBER 001, 002, etc.
14. Position the Receiver at the (+) post of the #1 cell, and the small probe at the (-) post of the #1 cell.
15. The display shows the (+) cell voltage and the impedance measurement. Pull the trigger to store the data.
16. For a moment the display will show the status of the cell compared to the baseline value, if entered.
17. The second line of the display shows STRAP. Move the Receiver to the (+) post of the next cell. The second display line shows
the strap impedance. Pull the trigger. The beeper sounds and the readings are stored.
18. The display advances to cell number (n+1). Repeat steps 14 through 17 until all cells are measured. After every fourth cell, the
amount of memory remaining in the Receiver is displayed.
19. After all the cells are measured, “short” the probe ends and pull the trigger. This creates a false strap measurement, which
completes the last line of data. If this is not done, the impedance, V DC, and strap resistance for the last cell will be lost.
20. Arrow key Up to review data, or arrow key Down to end the test sequence. When the display shows an action message, stop
and follow the instructions.
21. At this point, you may either close the test or print the active test to review the stored data. If the test is closed, no further
testing/retesting can be performed on that test.
22. Disconnect “CT” and probe, and turn off transmitter. Disconnect current source injection leads.
23. To print the data on the BITE 2P transmitter printer, connect the data transfer cable to “J3- RS232” port on the Receiver and
connect to “J3 – printer” port on the transmitter. The Receiver will prompt you for actions. All tests may be printed or only
selected test(s) may be printed.
24. To transfer data to the laptop computer, connect the data transfer cable to the INPUT port on the computer and the “J3 RS232” port on the Receiver.

25. The computer must be set to “download data from the Receiver." PowerDB must be loaded on the computer before you perform
this task. See the PowerDB instruction manual.
26. To complete the transfer, press “S” for EBITE/PC on the Receiver, then press “T” for PC. PLEASE WAIT appears in the display.
When transfer is completed, the display changes to POWER DOWN or EXPORT DATA.
