you may need to combine files to be able to compare data between charge cycles.
EVERY
time a USB flash drive is inserted into the charger, the charger needs to initialize the USB drive. There
are two practical methods to force initialize the USB drive.
1. Remove the AC and DC power from the
charger and let the display completely
extinguish. Restore AC power, the card will
reboot and will automatically initialize the
USB flash drive.
2. Leave the AC supply connected and on.
Connect the battery and close the breaker.
All the LEDs on the front panel will begin
slowly flashing. Press and hold the red
STOP button on the front of the charger for
about six seconds until the red “FAULT” LED
turns on solid. Release the STOP button.
After about 10 to 30 seconds the “FAULT”
LED will begin flashing with the rest of the
LEDs.
Now the charger and the USB flash drive are ready for the next charging cycle.
UNDERSTANDING THE LOG FILE
Below is an example of an actual output log file from the A75MD data logger. The title row has been modified
to conserve space on this page. This output file “lamarche.csv” will appear on the USB flash drive. This file
can be opened using Microsoft
®
Excel or other spreadsheet software. This document serves to help the end-
user to understand the information presented with the data log, and to interpret the results
Charger Serial Number
is programmed into the software at the factory. It is written to the top of the log file
to identify which charger each log belongs to.
Charge Count
shows how many charge cycles the charger has gone through.
The charge count is
independent of the battery and is tied to a particular charger. The charge count will not reset even if a USB
flash drive is removed, it will increment even on new USB flash drives. The charge count is almost like an
odometer for the charger.
Press and hold the STOP button for about six seconds
