Nulling
This option is available only from pop up menu in Stand By mode (accessible from
Menu
button).
During data collection (in Stand By mode) a confirmation message will be displayed (there
is no such message if Nulling is performed in Monitoring mode) before actual operation
is applied.
After above message is confirmed the program collects 50 readings and calculates the in-
strument offset.
The calculated offset is applied to all the readings that follow this operation. If needed, this
procedure can be repeated several times until satisfactory results are obtained. However,
there is no associated “Undo” function. If original values (without calculated offsets) of
the EM61-LX2 readings are needed, exit the EM61LX2 program and run it again. The
EM61-LX2 instrument does not have to be turned OFF.
