decimal digits will cause asterisks (****)

display.
Battery voltage runs down
The battery will slowly self-discharge
while a logger is sitting unused over time.
While being stored, the battery should be
recharged every two months. If the
battery voltage runs down over a very
short period of time, the battery may
need to be replaced. The batter in the
MDL units carries a 90-day warranty from
the date of purchase.
Logger fails to correctly ID a plugged in
module.
The module’s ID feature may have been
damaged due to electrostatic discharge.
The module’s other features should still
work fine. Simply select the module type
from the drop down menu on the Config
Parameters screen.
Note: This remedy may result in the
“Module ID Mismatch” message
appearing on the logger’s LCD. This is
normal because the logger can not
properly ID the module due to user
override of the module ID. The module
will still work properly unless it has
suffered more extensive damage.
Retrieve Data fails
If the MDL fails to “wake up” when
Retrieve Data is attempted, perform a
two-button press and then try to Retrieve
Data.

Communication
Problems
If your PC is having difficulty communicating with your MicroDataLogger unit (MDL):
1. First go to Preferences—Options in the MDL-DataManager menu, select Comm
Port/Modem option.
2. Select the proper comm port (COMM 1, 2, 3, or 4) to which your serial cable
connects.
3. Try again to communicate with your MDL.
4. If you still cannot communicate with your MDL, check the MDL’s battery voltage by
pressing the button 4 times. If the battery voltage reads 6.2 volts or less, or the
MDL’s LCD does not respond, recharge you MDL for 6-10 hours and try to
communicate again.
5. If you still are unable to communicate with your MDL, another software application
may have taken precedence over the com port needed to use the MDL. Such
applications include, but are not limited to: Palm Pilot® software, faxing software,
automated dial up applications. Even if these applications have not been opened
by you for use, they may be running in the background of your computer as part of
your computer’s Startup Menu. By disabling these applications when using MDL-
DataManager, you should be able to regain communication with your
MicroDataLogger unit to configure it for use or to download data from it.
