ALIBRATION
You can calibrate the OM-DLAC data logger to make its reading match an exter-
nal reference or standard. Set the OM-DLAC sampling rate long enough to allow
the logger and reference AC Current to stabilize. Make a recording along with an
external reference in a controlled environment so that the reference AC Current
for the second sample can be measured and recorded.
The calibration routine will use
the second recording sample to
make the logger reading match
with the external reference. Click
Tools
on the menu and click
Calibrate Logger. A calibration
password window will open. Type
your password in the Current
Password section. If you want to
have a new password next time,
you can type a new password in the New Password section. Click the
OK
button
when finished. If this is the first time you are calibrating the OM-DLAC, no pass-
word is needed. You can click the
OK
button or press the
Enter
key to continue.
If you have typed a password before and you don’t want password protection for
the calibration function, you can input None as the new password and this will
clear the password protection.
After you type the correct current
password and click
OK
, a
calibration window will open. You
can click the plus or minus
button to make the data logger
reading match with the reference
reading that you recorded at the
same time and same place with
the OM-DLAC. Click the
OK
button and the software will
make a new data retrieval based
on your new calibration setting.
The new calibration setting will be saved in the OM-DLAC and apply to all future
recordings.

EPLACEMENT
The OM-DLAC Data Logger uses a 9-Volt Alkaline battery, which will have an
average life of 1 year. The actual life of the battery will depend on a variety of
factors such as the temperature the battery is used in, the sampling rate of the
logger, and how often the OM-DLAC is used. Extreme temperatures will result in
reduced battery life. If the battery is exhausted during a recording, the OM-DLAC
