MadgeTech RHTemp2000
Section 9: Maintenance
The RHTemp2000 does not have any user-serviceable parts except the bat-
tery 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 RHTemp2000 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 battery, locate and remove the four (4) 3/32 hex screws on
the back of the unit. Separate the halves and the battery compartment is
now visible. Remove the old 9V battery from the battery clips and replace
with a new 9V battery. MadgeTech recommends using 9V lithium battery. An
alkaline battery is acceptable, but will yield a shorter battery life.
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
