Setting-up
Supplying Power to the Model 9565 Series
The Model 9565 VelociCalc
®
Air Velocity Meter can be powered in
one of two ways: four size AA batteries or the AC adapter.
Installing the Batteries
Insert four AA batteries as indicated by the diagram located on
the inside of the battery compartment. The Model 9565 is
designed to operate with either alkaline or NiMH rechargeable
batteries. Battery life will be shorter if NiMH batteries are used. If
NiMH batteries are used the DIP switch will need to be changed.
Refer to the next section, DIP Switch Settings. Carbon-zinc
batteries are not recommended because of the danger of battery
acid leakage.
DIP Switch Settings
To access the DIP switch, remove the batteries from the battery
compartment. On the inside of the battery compartment, there is
a window with a single DIP switch (see figure below). The table
below shows the functions for the switch.
Make certain that power is turned off before changing
the DIP switch settings.
