EM61MK2 Data Logging System (DAS70/61MK2)
This function allows operator to delete previously recorded reading(s). The reading (station)
to be deleted is displayed on the screen. The data will only be deleted when the key
D
is
pressed. The program will then display the next previous station, and allow it to be deleted
in a similar fashion. If there is no further data available, the program will provide related
information.

N
(Nulling)
To perform null of the instrument press the key
N
. During data collection a confirmation
message will be displayed (there is no such message if Nulling is performed in Monitoring/
Nulling menu).
After above message is confirmed the program collects 25 readings and calculates the
instrument 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-MK2 readings are needed, exit the EM61MK2A program and run it again. The
EM61-MK2 instrument does not have to be turned OFF.
I
(Internal QC Coil Calibration)
The Internal QC coil calibration is described in detail in the EM61-MK2 Operating
Instructions.
To start the calibration using Internal QC coil press key
I
. This action begins by performing
the automatic nulling which in this case is only in effect for the duration of the calibration
process. It will not affect EM61-MK2 readings. After the nulling is completed (less than 5
seconds) the Internal QC coil Calibration screen is displayed.
