
The Fan Filter covers the air intake to keep dust and debris out of the chassis air baffles. The
5522A fan provides a constant cooling air flow throughout the chassis. Instructions for fan filter
maintenance are in Chapter 7, Maintenance.

The CALIBRATION NORMAL/ENABLE slide switch is used to write enable and disable the
nonvolatile memory that stores calibration constants. Switching to ENABLE allows changes to be
written into memory, and switching to NORMAL protects data in memory from being overwritten. The
switch is recessed to allow it to be covered with a calibration sticker to guarantee calibration
integrity.

The SERIAL 2 TO UUT connector is used for transmitting and receiving RS-232 serial data between
the 5522A and a Unit Under Test (UUT) or a Fluke 700 Series pressure module. Chapter 6, “Remote
Commands” describes how to use the RS-232 serial interface for UUT communications. Chapter 4
described how to measure pressure.

The SERIAL 1 FROM HOST connector is used for remote control of the 5522A and for transmitting
internal-constant RS-232 serial data to a printer, monitor, or host computer. Chapter 5, “Remote
Operation” describes how to use the RS-232 serial interface for remote control.

The 10 MHz IN BNC connector is for applying an optional external clock signal to the 5522A. This
replaces the normal internal 10 MHz clock signal in the 5522A. Frequency accuracy of the 5522A is
governed by the frequency accuracy of the clock signal internal or external.
The
10 MHz OUT BNC connector passes the internal or external 10 MHz clock signal to another
5522A to synchronize one or more slave 5522As to a master 5522A.

The IEEE-488 connector is a standard parallel interface for operating the 5522A in remote control as
a Talker/Listener on the IEEE-488 bus. Refer to Chapter 5, “Remote Operation” for bus connection
and remote programming instructions.
