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.
