ALIBRATION
You can calibrate the OM-DLAV data logger to make its reading match an exter-
nal reference or standard. Set the OM-DLAV sampling rate long enough to allow
the logger and reference AC voltage to stabilize. Make a recording along with an
external reference in a controlled environment so that the reference AC voltage
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-DLAV, 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 pass-
word 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 re-
corded at the same time and same
place with the OM-DLAV. 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-DLAV and apply to all future recordings.
