Maintenance/Calibration
3.1 Battery Replacement
The PRIMA 7 uses four (4) AA cells. Mallory type MN1500 alkaline cells are preferable to the normal
carbon cells because the alkaline cells will give approximately 10,000 measurements in normal service.
The instrument may be shipped with the batteries packed separately. To install or replace batteries,
remove the single screw in the center of the back of the case to expose the battery holder. Note carefully
how the case is installed. Insert cells with negative terminals on the springs. (Note + markings on battery
holder.)
3.2 Calibration
The PRIMA 7 is calibrated at the factory, using a 137 Cs standard and should not need to be readjusted in
the field.
