MadgeTech PR2000
Section 9: Maintenance
The PR2000 does not have any user-serviceable parts except the battery
which should be replaced periodically. The battery life is affected by battery
type, ambient temperature, sample rate, sensor selection, offloads and LCD
display usage. The PR2000 has a battery status indicator on the LCD display.
If the battery indication is low, or if the device seems to be inoperable, it is
recommended that the battery be changed.
To change the batteries, locate and remove the four(4) 9/64” hex screws
on the back of the unit. Separate the halves and the battery compartment is
now visible. Remove the old AA batteries from the battery holder and replace
with six(6) new AA alkaline batteries as indicated on the holder. When re-
placing the cover, make sure that the gasket is still seated in its groove, and
that all wires are tucked away inside the compartment.
For any other maintenance or calibration issues, MadgeTech recommends
the unit be returned to the factory for service. Before returning the device,
you must obtain an RMA from the factory. For further information, please
