DATA LOG OPTION
OBTAINING LOG FROM UNIT
In order to review the data log files from the A75MD, you will
need to have access to a computer. This can be a laptop
brought down into the mine, or a computer that is above
ground. If you plan to bring the data above ground you will
need to bring an additional USB flash drive underground. The
data logging will continue on the replacement flash drive.
The disadvantage to this is that the log will become split
making it harder to compare charge cycles. Bringing a laptop
underground allows you to just copy the file over and put the
flash drive back into the charger.
Before beginning allow the charger to finish the current
charge cycle. After the charge cycle is complete, disconnect
the battery and wait approximately one minute for the
charger to write the last charge cycle to the USB drive. There
is no indication that the file has been written so be sure to
wait a full minute after the battery has been disconnected.
When the charger has finished the charge cycle and the
battery is disconnected you may remove the USB flash drive.
It is not necessary to remove AC power from the charger; the
USB compartment is isolated from the power system. Open the
USB access door with a #2 Philips screwdriver and remove the
USB flash drive.
If you are reading the USB drive underground, simply copy the
“LAMARCHE.CSV” file and paste it to you desktop. Do not
delete or otherwise alter the original file. After the file has
been copied to the laptop immediately plug the USB drive back
into the charger and screw the access door closed.
If you are reading the USB drive above ground,
immediately replace the USB drive with another
USB drive that has been formatted for use with
the A75MD. Some USB drives come with file
management and/or security software pre-
installed. You must format the drive to remove
these options as they make the drive
incompatible with the A75MD. Once a USB
drive has been successfully used in the A75MD,
it will not need to be formatted again.
Note: If you choose to use multiple USB drives,
the log will be spread across all of these drives;
